Chapter 1: Introduction and General Information

The B&B Electronics’ 3PXCC4A series serial interface cards are designed for the IBM PC, XT, AT and compatibles. Ports are configured as a standard DTE device, and connections are made on RJ45 style connectors.

The 3PXCC4A cards offer exceptional setup flexibility. The 3PXCC4A series has the ability to use any I/O address and any hardware interrupt. You can install as many serial ports as will physically fit in a machine. To use one of the “non-standard”addresses or interrupts, the serial software used must also offer that flexibility. If you are writing your own application, be sure the communications routines used support any address and IRQ. B&B Electronics’ SimpCom Communications Drivers support these features.

Features

Each port independently configurable for any hex address 0 to hex 3F8 including COM1 – COM4

Each port independently configurable for any interrupt: 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15

Shared IRQ capability with Interrpt Status Register

Each port independently configurable for RS-232/RS-422orRS-485

Jumper selectable interrupts: 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15

Enhanced 16 bit Address Decoding

Baud rates up to 460.8K baud in RS-422/RS-485Mode, 115.2K baud inRS-232Mode

16550A UARTs on all ports

RS-232mode supports lines: TD, RD, RTS, CTS, DSR, DCD, and DTR

RS-422/RS-485mode supports lines: TD and RD

RTS control of RS-485driver enable

Can be wired for half or full duplex RS-485communications

Chapter 2: Quick Installation Guide

The following steps will help you install the Model 3PXCC4A Serial Card. Please follow (step-by-step)the following numbered instructions and refer to any corresponding chapters for more details.

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. After setting the jumper, 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.

1.Make sure you have an available ISA slot for installing your B&B Electronics Serial Card. You may have to remove the cover of your PC.

2.Determine what addresses and IRQ’s are free to use on your PC by checking your operating system for unused addresses and IRQ’s. Each port uses eight I/O address spaces starting at the base address that you select. Each port I/O address and interrupt request (IRQ) must be set as well. See “Checking Device Manager for Available Address/IRQ’s” in Chapter 3 for your operating system. Refer to Chapter 4 (Table 3) for frequently unused I/O addresses and IRQ’s. Write down the address and IRQ you select to use. Do not physically install the ISA card at this point.

3.Add New Hardware – This consists of adding a port or ports to your operating system. See “Adding Serial Ports” in Chapter 3 for specific instructions for your operating system.

4.Assign Address and IRQ – The address and IRQ are set in the operating system that you are using. This is the final step of adding new hardware. See Chapter 4 for more details.

5.Set up the address (with dipswitches) and IRQ (jumpers) on the serial card to reflect unused addresses and IRQ’s that you want to use. The address dipswitch setting consists of configuring seven dipswitches that reflect a particular hex address. The IRQ is set via a little black jumper. See Chapter 4 for an explanation of address and IRQ settings as well as details on configuring the card itself.

6.Set serial card hardware jumpers for the communication parameters that you desire. See Chapter 5 for an explanation of serial parameters and details on how to configure them.

7.Shut down the PC before installing the serial card.

8.Install ISA serial card into an available ISA slot in the PC.

9.Physical Hook-upand Troubleshooting – pinout, cable data, and troubleshooting information. See Chapter 6 for more details.

Scroll through the list, check 03F8H, 02F8H, 03E8H, 02E8H. If one of these is available, use it. If not, check alternates.

Find a free address in the list. Most desktop PC’s have a COM1 and possibly a COM2 already on their system which will be seen in the list. You might have to start at COM3 or COM4 to begin addressing the ISA card. If these addresses are used you may have to resort to the Frequently Unused Port Addresses (found in Chapter 4, Table 3) of this manual. Write these open addresses and IRQ’s down for later reference.
