Chapter 1: GENERAL INFORMATION

Introduction

The B&B Electronics 3PCIOSD1x single port isolated serial interface card is designed for IBM compatibles with a PCI Bus. The PCI design is Plug and Play compatible which allows the driver and Operating System to select the IRQ and addresses used by the card.

The 3PCIOSD1x cards offer exceptional setup flexibility with a mix of selectable operating modes. If you are writing your own applications, be sure the communications routine used supports Windows communication drivers and a wide range of COM ports.

Description

The isolated single port can be configured for RS-232,RS-422,orRS-485data protocols. TheRS-485mode automatic Send Data Control feature transparently handles the enable and disable functions of theRS-485transceiver.

Chapter 2: SETUP

Inspection

Your 3PCIOSD1x serial card was tested for proper operation before shipment. It should be in perfect mechanical and electrical condition upon receipt.

The card is normally pre-configuredforRS-232operation.

The data clock speed is set by one jumper to x1 (normal) operation or to x4 operation.

The operating mode of the card is set using 8 jumpers: 4 jumpers select RS-232operation orRS-422/485operation, one jumper sets RTS forRS-232&RS-485modes or Send Data forRS-485mode, 2 jumpers selectRS-422orRS-485operating modes for Receive and Transmit, and the last jumper selects 120 ohm termination for theRS-422orRS-485Receive.

Refer to Jumper Mode Tablein Appendix C.

CAUTION: ELECTROSTATIC SENSITIVE DEVICE

Use ESD precautions for safe handling.

Before removing the card from the anti-staticprotective 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-wirepower cord.

Avoid touching the gold connectors or other parts on the card except as necessary to set the configuration jumpers. After setting the jumpers, ground yourself to the computer chassis before and while inserting the card.

Remove AC power from the computer and unplug the power cord before inserting the card.

Retain the ESD bag for handling the card. Save the packaging for storage or shipping.

RS-422Mode

To configure the port for RS-422mode, 7 jumpers must be set/checked. The following settings configure the port asRS-422:

1.Set the four jumpers of JP2 (A-D)to the "422/485" (right) position.

2.Set the top jumper "TX" of JP4 to the “422” (left) position.

3.Set the second jumper "RX" of JP4 to the “422” (left) position.

4.The JP1 Control (SD/RTS) jumper is unused in the RS-422mode and may be in either position.

5.The bottom jumper "Termination" of JP4 switches the 120Ω receiver termination resistor IN or OUT. Typically this resistor is not used. In some cases using high baud rates and very long cables, termination is needed. See B&B’s free RS-422/485 Application Note, Termination section, page 16, for more information (available on our websites). Figure 3 shows the jumper configuration to set the port forRS-422mode with *1 clock enabled.

With 2-wireRS-485mode operation, your connection cable must jumper TD(A) to RD(A) and TD(B) to RD(B). Connect from TD(A) and TD(B) to the Data A(−) and Data B(+) wires of yourRS-485network.

Note that the EIA RS-422Specification labels data lines with an "A" and "B" designator. SomeRS-422equipment uses a "−" and "+" designator. In almost all cases, the "A" line is the equivalent of the "−" line and the "B" line is the equivalent of the "+" line.More information on RS-422 communications can be found in B&B’s free RS-422/485 Application Note (available on our websites).

RS-485Mode

To configure the port for RS-485mode, 8 jumpers must be set/checked. The following settings configure the port asRS-485:

1.Set four jumpers of JP2 (A-D)to the "422/485" (right) position.

2.Set the top jumper "TX" of JP4 to the “485” (right) position.

3.For 2-wireoperation, set the second jumper "RX" of JP4 to the "485" (right) position (half duplex). For4-wireoperation, set it to the "422" position (full duplex, Receive enabled)

4.Set the JP1 Control jumper to select the type of RS-485transmit driver control, automatic Send Data (SD) or RTS . Select SD control unless you are sure that your software requires RTS control.

RS-485Pinouts

The pinouts in RS-485mode are the same as those listed inTable 2: RS-422/485 Pinouts on the previous page.

Explanation of RS-485Operation

In RS-485mode, the transmit driver must be enabled to transmit, and set to a high impedance(tri-state)mode at the end of transmission. In two wire (half duplex) mode, the receiver is disabled during transmit, and enabled when not transmitting.

The 3PCIOSD1x card provides two methods of enabling/disabling the transmit driver, automatic Send Data (SD) control and Request To Send (RTS) control. With automatic SD control, the driver is enabled when data is sent. The driver remains enabled for the transmission time and ten data bits after data transfer is complete. The SD circuit automatically adjusts its timing to the baud rate of the data. With RTS control, software must assert the RTS line to enable the driver and de-assertto disable the driver. To select SD control for the port, place JP1 jumper in the “Send Data” (left) position. Place this jumper in the “RTS(232)” (right) position for RTS control.

The receiver can also be enabled and disabled, a useful feature in two-wirecommunications to prevent the transmitted data from "echoing back" on its own receiver. The second jumper "RX" of JP4 determines the receiver mode. When the jumpers are placed in the “485” position, the "echo" is turned off. This is achieved by disabling the receiver when the transmit driver is enabled. Placing this jumper in the “422” position will hold thereceiver enabled at all times.More information on RS-422 communications can be found in B&B’s free RS-422/485 Application Note (available on our websites).

RS-422andRS-485Termination

A 120Ω termination resistor has been provided for the RS-422/485receiver. Note that termination should only be used in systems with both high baud rates (>19200) and over several thousand feet of cable. If a value other than 120 Ω is desired, space for a throughhole resistor has been provided on the board adjacent to the surface mount termination resistor. Thisthrough-holetermination resistor is labeled as RTAB while the surface mount termination resistor is labeled as RTAA.See B&B’s free RS-422/485 Application Note, Termination section, page 16, for more information (available on our websites).

RS-485Network Biasing

Biasing is required on an RS-485network to hold the network in the marking state between transmissions. The 3PCIOSD1xRS-485receiver is biased with a 4.7 KΩpull-upresistor (R28A) on the Receive Data B line and a 4.7 KΩpull-downresistor (R29A) on the Receive Data A line. These values are usually adequate for networks without termination and small numbers of nodes. For more complex networks, the user must calculate the required value and replace these resistors. Space forthrough-holeresistors has been provided over the top of the surface mount components placed at the factory. Thethrough-holeresistor for thepull-upis marked as R28B and thepull-downis marked as R29B.

4 X Baud Rate Option

Baud rates higher than 115,200 are possible with the 3PCIOSD1x card in RS-232,422, or 485 mode. Jumper JP3 controls the clock frequency supplied to the UART. By moving this jumper to the “*4” (left) position, the clock frequency is increased from 1.8432 to 7.3728 MHz. This multiplies all UART baud rates by 4 times. For example, if the software is set for 57.6K baud, the actual baud rate will be increased by a factor of four to 230.4K baud. In many systems, these higher baud rates can improve throughput significantly. However, remember that baud rates and actual throughput are only proportional if the system can keep up with the communications, otherwise increasing the baud rate effectively only increases the idle time between characters.

Installing the Card

1.Ground yourself by touching the metal chassis of the computer to discharge any static electricity.

2.Turn the power to your computer off and unplug the power cord.

3.Remove the cover of the computer.

4.Locate a free PCI expansion slot.

5.Remove the expansion slot cover. Save the screw for installation of the 3PCIOSD1x card.

6.Install the card into the unused slot. Be certain that the card is inserted completely (fully seated) in the slot.

7.Secure the card with the mounting screw from step 5.

8.Replace the cover, plug in the power cord, and power up the system.
