Chapter 2: Setup Inspection Your 3PCI2 serial card was tested for proper operation before packaging. It should be in perfect mechanical and electrical condition upon receipt. CAUTION: ELECTROSTATIC SENSITIVE DEVICE Use ESD precautions for safe handling. Before removing the card from the anti-static protective packaging: • Discharge any static electricity buildup on your body by touching a large grounded metal surface or the metal chassis on equipment connected to earth ground by a 3-wire power cord.
Selection of Operating Mode The hardware address and IRQ is set by the Windows Operating System using driver information files and the Plug and Play OS. The Operating Mode is set using Jumpers, Device Manager Driver Settings and by your cable connections and software. Set the Jumpers Set JP1 and JP2 Jumpers to match your Operating Mode.
The top jumper sets DB9 connections for either 232 or 422/485. RS-232 operation requires setting only the Top jumper. The middle jumper sets the RS-422/RS-485 transmitter for RS-485 or RS-422 operation. In RS-485 mode, the transmitter is tri-stated when not sending data. In RS-422 mode, the transmitter is always enabled. The bottom jumper sets the RS-422/RS-485 receiver for half-duplex RS-485 operation or full-duplex RS-422/RS-485 operation.

Data Rate - 1X or 4X Clock Speed Each 3PCI2 port in the Device Manager has Data Rate, Clock Speed settings for normal 1X or 4X. The 4X position provides a compatibility mode for software which requires it. In the 4X position, all specified baud rate settings are multiplied 4 times. For example, if the software specifies 57.6K baud, the actual baud rate will be 230.4K baud, 115.2K becomes 460.8K baud. Each port can be set separately.
FIFO Settings The default FIFO settings should minimize overhead and work well for most users. The FIFO Interrupt Trigger levels setting determines how often the host processor services the serial port to send or receive data. The Transmitter Trigger level sets how low the output buffer gets before it triggers a request for more data from program memory. The Receiver Trigger level sets how much data is in the input buffer before it triggers a request to read the data from the buffer to program memory.
The optimum setting for each depends on the nature of your data, how it fits within the buffer, how fast your computer operates, etc. Receiver FIFO applies when Handshaking is used for Hardware or Software control. For Connections, refer to Chapter 5, RS-232 or Chapter 6, RS-422 or RS-485.

Chapter 5: RS-232 Connections/Operation The DB-9 male connectors on the card are configured as standard RS-232 (DTE) serial ports. Table 3 shows the signal names and pin numbers.
There are two types of RS-232 ports, DTE (Computer) and DCE (Modem). Connected directly together using a modem cable wired pin to pin, the inputs match the outputs of the other. When two of the same type (DTE to DTE or DCE to DCE) are interconnected, a crossover (null modem) cable is needed to route the outputs of one to the inputs of the other. This type of cable is needed to interconnect two computers with RS-232.
Chapter 6: RS-422/RS-485 Connections/Operation These modes support 2 channels - transmit and receive. The pinouts of the DB-9 male connector are given in Table 4. Table 4: RS-422/485 Pinouts Name Description Direction DB9M Pin Receive Data A Input RD(A) − TD(B) + Transmit Data B Output Transmit Data A Output TD(A) − GND Signal Ground -----RD(B) + Receive Data B Input Connect only to specified pins for proper operation. 1 2 3 5 9 2-Wire RS-485 Connections Fig. 6.
4-Wire RS-422 or RS-485 Connections Figure 6.2 Note: With RS-422 Devices, connect only one device to computer. Connect the TD(B) pin #2 on the computer to RD(B) on the device. Connect the TD(A) pin #3 on the computer to RD(A) on the device. Connect the RD(B) pin #9 on the computer to TD(B) on the device. Connect the RD(A) pin #1 on the computer to TD(A) on the device. Connect the Signal Ground pin #5 to Signal Ground on the device.
Figure 6.3 RS-422 & RS-485 Differential Signals In RS-422 and RS-485 modes each signal is differential. When one line is high (4.4V) the other is low (0V), they alternate voltage with data. The receiver is differential so that common mode noise picked up on the twisted pair of wires is cancelled. Receiver sensitivity is rated at 200mV. A separate signal ground/common connection provides a common mode reference for the transmitter and receiver.
This limitation is due to the fact that the transmitter is active all the time, and the line pair is set so that the TD(B) line is high during Mark state, and the TD(A) line is set low. If another transmitter output is connected to the same wire pair, and attempts to send data by setting the line pair to Space state, the first transmitter is still trying to hold the opposite state and neither can communicate.
The RS-485 mode is set using 3 jumpers per port, and by selecting the RS-485 Mode for DTR Operation on that com port. RS-485 Network Biasing In an RS-485 network, the transmitter tri-states to a high impedance state. Unlike RS-422 where the transmitter holds the TD(B) line high and the TD(A) line low (Mark state) when not transmitting data. To establish and maintain the Mark state for all RS-485 receivers, Biasing is required.
Chapter 7: Troubleshooting If you have any trouble starting your system after installing the card, the card may not be properly seated in the slot. Remove and reinsert it or try a different slot. Check that BIOS is set for PnP OS. If you are unable to communicate with the card using your software and hardware devices: 1. Check your pinouts In RS-422 or RS-485 mode the "A" lines should match your "A" or "−" lines. "B" lines should match your "B" or "+" lines. Note: RS-422/485 pinouts are non-standard. 2.
3. Run Setup.exe to install COMTest on your program menu under B&B Electronics. 4. Check your Card Jumpers, and Driver Settings. See Chapter 2. 5. Make sure you have DTR Operation set to the correct mode. Normal for RS-232, RS-485 Mode for RS-485. RS-422 mode works in either setting provided that the mode jumpers are set correctly. 6. A loopback connection for RS-232 connects the Transmit output to the Receive input (pins #2 & #3 on the DB9 connector). Use connections below to check all. Fig. 7.
Fig. 7.3 RS-485 Connections for 2-Wire Mode 8. To check 2-wire RS-485, you must either enable the receiver by moving the receive jumper to RX ENABLE mode (Table 1), or use one port to transmit to another by cross connecting (Fig. 7.3) and loading COMTest twice, one copy for each port. Characters typed in one copy of COMTest will appear in the receive window of the other.
