This high performance 3-stage lightning protector provides superior protection of differential or balanced digital or analog lines from transients and surges. The units will protect two pairs of differential data or analog signal\/control lines. \u003cbr\u003e\u003cbr\u003e The first stage is comprised of a differential gas discharge tube. Stage two is a pair of current limiting series resistors and the final stage is a low capacitance diode array. The use of three terminal differential gas discharge tubes provides superior common and differential mode protection against conducted transients versus the use of lower cost two terminal tubes. The second stage series resistance limits the power dissipation of the fast diode clamp array in the third stage. This allows time for the slower but higher power gas tubes to flash over. The diode array clamps the leading edge of fast transients to safe levels until the high power gas tubes turn on. This eliminates the damaging leading edge spike that single stage gas tube protectors let leak through. The diode array's low capacitance assures that the suppressor will not degrade the high-speed signals. The 3-stage design can handle higher-level transients than a protector that uses only diodes. \u003cbr\u003e\u003cbr\u003e For more complete surge protection of data lines, the use of two units is recommended, one at each end of the line.\u003cbr\u003e\u003cbr\u003e \u003cb\u003eOutdoor Use\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e The compact weather resistant housing features a lockable hinged cover and mounting holes are provided on the rear of the enclosure for mounting.

Data lines are opto-isolated from the computer and from each other to assure communication even when large common mode voltages and noise are imposed. By means of jumper placement on the card, each port can be setup for either RS-485 or RS-422 operation. RS-422 operation uses differential balanced line drivers for long range and high noise immunity. RS-485 operation improves on that by providing multi-drop capability for as many as 32 devices. RS-485 communication requires that one device on the network provide a bias voltage to ensure a known inchƒ¦“zero inch state when all transmitters are off. Also, receiver inputs at each end of the network should be terminated to avoid inchƒ¦“ringing inch. Both ports on the 104-ICOM-2S support those needs, bias is provided as a standard, and termination by means of jumper selection.\u003c\/p\u003e\n\u003cp\u003eThe card supports half-duplex and full-duplex communications in 2- and 4-wire cable connections. Half duplex allows traffic to travel in both directions, but only one way at a time. In full-duplex operation, data travels both ways at the same time. Most RS-485 communications use the half-duplex mode because only a single pair of wires needs to be used and installation costs are dramatically reduced. In RS-485 operation the driver must be enabled and disabled as needed to allow all cards to share a two wire or four wire cable. Auto-RTS control circuits on the 104-ICOM-2S enable the driver when data is to be transmitted. When transmission is complete, the driver is automatically disabled. The receiver at that port is disabled during transmission time and then enabled at the completion of data transmission.\u003c\/p\u003e\n\u003cp\u003eType 16550 UART inchs are used.

For low profile systems please use  LPCI-COM-1S for the card to be shipped with a low profile bracket.\u003c\/p\u003e\u003cp\u003eThe card supports RS-422 and RS-485 balanced-mode transmission\/reception. Each card has capability to add bias voltage. (RS-485 communication requires that one transmitter in the network must supply a bias voltage to ensure a known 'zero' state when all transmitters are OFF). Also, receiver inputs at each end of the network should be terminated to eliminate ringing. The card supports these options by means of jumpers on the card.\u003c\/p\u003e\u003cp\u003eType 16550 UARTs are used as the asynchronous communication elements.

Higher baud rates, up to 460,800 baud, are achieved by changing a jumper on the card. The driver\/receivers used, type 75176, are capable of driving extremely long communication lines at high baud rates. They can drive up to ±60 mA on balanced lines and receive inputs as low as 200 mV differential signal superimposed on common mode noise of +12V to -7V.

However, they are available without that cable as models LPCI-COM422\/8S1 and LPCI-COM485\/8S1 for OEMs that fabricate their own cable harnesses.\u003c\/p\u003e\n\u003cp\u003eType 16C550 UARTS are used as the asynchronous communication elements. These include a 16-byte transmit\/receive FIFO buffer to protect against lost data in multitasking systems while maintaining 100% compatibility with the original IBM serial port. ACCES also offers16850 UART functionality as an option to lower the CPU loading and allow for error-free data communications even at high simultaneous data rates.\u003c\/p\u003e\n\u003cp\u003eCrystal oscillators located on the cards permit precise baud rate capability up to 115,200. Higher baud rates, up to 921,600 baud, are achieved by changing a jumper on the card. The driver\/receivers used, type SN75176B, are capable of driving long communication lines at high baud rates. They can drive up to ±60 mA on balanced lines and receive inputs as low as 200 mV differential signal superimposed on common mode noise of +12 to -7V. In case of communication conflict, the driver\/receivers feature thermal shutdown.\u003c\/p\u003e\n\u003cp\u003eSince these are PCI-Bus cards, the operating system determines the resources assigned to the card. As a result, you cannot set or change the card's base address. You can only determine what the system has assigned. The PCI Bus supports 64K of I\/O bus address space so your cardžs address may be located anywhere in the 0000 to FFFF range.\u003c\/p\u003e\n\u003cp\u003eAUTO TRANSCEIVER CONTROL\u003c\/p\u003e\n\u003cp\u003eIn RS-485 communications, the driver must be enabled and disabled as needed, allowing all cards to share a two wire cable. The LPCI-COM485\/8 card controls the driver automatically. With automatic control, the driver is enabled when data is ready to be transmitted. The driver remains enabled for one additional character's transmission time after data transfer is complete and then is disabled. The receiver is also normally enabled, then disabled during RS-485 transmissions, and then re-enabled after transmission is completed (plus one character transmission time). The LPCI-COM485\/8 automatically adjusts it's timing to the baud rate of the data. (NOTE: Thanks to the automatic control feature, the card is ideal for use in WIN9x\/NT\/2K\/XP applications)\u003c\/p\u003e\n\u003cp\u003eUTILITY SOFTWARE\u003c\/p\u003e\n\u003cp\u003eA complete driver support package is provided including an easy to use Windows terminal program for testing out your COM ports. This helps simplify verification of proper operation. The card installs as standard Windows COM ports in all Windows operating systems including the ability to re-direct the starting COM port number at COM3 in Windows NT 4.0. The card is supported by most operating systems and includes a free DOS, Linux and XP -\u0026gt; 10, both 32 \u0026amp; 64 bit compatible software package.

Data lines are opto-isolated from the computer and from each other to assure communication even when large common mode voltages and noise are imposed.\u003c\/p\u003e\n\u003cp\u003eBy means of jumper placement on the card, each port can be set up for either RS-485 or RS-422 operation. RS-422 operation uses differential balanced line drivers for long range and high noise immunity. RS-485 operation improves on that by providing multi-drop capability for as many as 32 devices. RS-485 communication requires that one device on the network provide a bias voltage to ensure a known \"zero\" state when all transmitters are off. Also, receiver inputs at each end of the network should be terminated to avoid \"ringing\". Both ports on PCI-ICM-2S support those needs by means of jumpers on the cards.\u003c\/p\u003e\n\u003cp\u003eThe card supports half-duplex and full-duplex communications in 2- and 4-wire cable connections. Half duplex allows traffic to travel in both directions, but only one way at a time. In full-duplex operation, data travels both ways at the same time. Most RS-485 communications use the half-duplex mode because only a single pair of wires needs to be used and installation costs are dramatically reduced. In RS-485 operation the driver must be enabled and disabled as needed to allow all cards to share a two wire or four wire cable. Control circuits on PCI-ICM-2S enable the driver when data are to be transmitted. When transmission is complete, the driver remains enabled for the transmission time of one additional character and then is automatically disabled.

Model ICOM-1S is a single-port, de-populated version of this card. The opto-isolators assure reliable communication when large common mode noise is superimposed on the transmit\/receive lines. Opto-isolators are also provided on the RTS and CTS handshaking control lines. Further, an on-board DC-DC converter provides isolated +5 VDC to power the transceiver and RTS and CTS circuits. Transorbs are optionally available to absorb potentially damaging voltage spikes created by equipment or lightning.\u003c\/p\u003e\n\u003cp\u003eThe card supports all of the most popular asynchronous communication protocols. RS-422 mode differential drivers extend the distance and speed. RS-485 mode uses tri-state drivers to produce a multi-drop network of up to 32 cards on a single twisted pair. RS-485 multidrop communications requires the transmitter drivers to be enabled and disabled as needed to allow the ports to share the common communication lines. These cards have two methods to control the drivers: automatic (AUTO) and Request to Send (RTS) control. Under automatic control, the port is normally in the receive mode and the driver is enabled only when data is ready to be transmitted. The driver is then enabled and remains enabled throughout the transmission plus the transmission time of one character after data transfer is complete. Then it is disabled. The cards automatically adjusts their timing to the baud rate of the data. When operating with Windows programs, this AUTO mode is mandatory. With RTS control, your application software must enable\/disable the driver.\u003c\/p\u003e\n\u003cp\u003eThe card is 100 percent compatible with MS-DOS with support for the standard COM1 through COM4 serial port address. However, you are not limited only to those addresses. Continuous address selection is available anywhere in the I\/O address range of 000 to 3FF (hex). Interrupt levels from IRQ2 to IRQ14 (Except for IRQ 8, 9, and 13 which are always reserved by the IBM hardware) are supported. A crystal controlled oscillator is located on the card. This oscillator permits selection from standard baud rates from 50 to 115,200 baud. The opto-isolators limit operation to 38,400 baud but higher speed isolators are optionally available. For operation above 115K baud a non-isolated card, such as the COM-2S, which has the capability of even higher speeds should be considered.\u003c\/p\u003e\n\u003cp\u003eThe transceiver used, a type 75176, is capable of driving extremely long communication lines at high baud rates. It is capable of driving up to 60 mA on balanced lines and receiving inputs as low as 200 mV differential signal. Also, in case of communication conflict, the transceivers feature thermal shutdown.\u003c\/p\u003e\n\u003cp\u003eIn addition to differential Transmit and Receive lines, single-ended, buffered RTS and CTS lines are provided at the I\/O connector. Normally, CTS must be pulled up to +5 VDC for the card to operate but you can position a jumper so that the cardwill auto-detect the transition between transmit and receive operations. These cards support full duplex, half duplex and simplex operations selected by jumpers.\u003c\/p\u003e\n\u003cp\u003eA transmission line should be terminated at the receiving end in its characteristic impedance. You can install a jumper (LD) which applies a 136 ohm load across the input for RS-422 mode and across the transmit\/receive input\/output for RS-485 operation. When noise is a potential problem on long lines, the terminating resistor should be divided and its center point grounded to help reduce noise voltage pickup.

If a computer fails it can cause catastrophic damage. There are two methods to reduce risk of computer failure; (a) redundancy and (b) a watchdog circuit. Neither method offers 100% assurance but both of these methods reduce risk or consequences of failure. Redundancy, a duplication of computer circuitry, is very expensive. On the other hand, ACCES' Watchdog card offers excellent protection from temporary malfunctions at very low cost.\u003c\/p\u003e\n\u003cp\u003eThe watchdog timer provides means for automatic computer reset in case of processor failure, faulty programs, electrical noise, and some component failures. The circuit works as follows: A countdown timer is periodically loaded by the application program. The application program must communicate with the watchdog circuit at prescribed intervals. If this communication (\"prompt\") is missed, the Watchdog counter is not updated, reaches zero, and provides an output that can be used to reset the computer. If the failure was temporary, proper operation is resumed. If, however, the failure is persistent, the Watchdog will continuously reset the computer. The more frequently the computer is prompted (and shorter Watchdog time selected), the less time a faulty computer has to cause damage.\u003c\/p\u003e\n\u003cp\u003eImplementation of this watchdog procedure can be accomplished by your application program, by AUTOEXEC.BAT, or by other appropriate software.\u003c\/p\u003e\n\u003cp\u003eA type 8254 counter\/timer chip is used in the Watchdog circuit.

The 8254 counter\/timer chip contains three 16-bit counters and the clock source is a crystal oscillator on the card that is independent of the computer clock. Counter\/Timers 1 and 2 are used by the Watchdog circuit. If timeout periods of 25 milliseconds or greater are desired, then counter\/timer 2 is the only one used and placement of a jumper applies 225 Hz pulses to that counter. If timeout periods of less than 25 milliseconds are desired, then you can place a jumper that connects the output of counter\/timer 1 to counter\/timer 2 and a DIP switch permits selection of crystal-controlled clock frequencies of 3.6 KHz or greater. The watchdog time-out is programmable from 5msec to 291 seconds. Counter\/timer 0 is available for general purpose use. If not required for the Watchdog time-out period, counter\/timer 1 is also available.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Status Register\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAn ambient-temperature sensing circuit and a voltage monitor circuit are included on the card.
