Chapter 1: Introduction and General Information

The B&B Electronics’ 232CC series RS-232 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 9-pin D-style connectors.

The 232CC cards offer exceptional setup flexibility. The 232CC
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

Switch selectable addresses, from 0 to hex 3F8, including

COM1 – COM4

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

Enhanced 16 bit address decoding

Baud rates up to 230.4K baud with 2X clock option enabled

16550A UARTs on all ports

Supports all standard RS-232 lines: TD, RD, RTS, CTS, DSR, DCD,
DTR, and RI

Specifications

I/O connection: 9-pin male, D-sub connectors

Baud rates: 230,400 baud max with 2x clock jumper enabled

Character length: 5, 6, 7, or 8 bits

Parity: Even, odd or none

Chapter 2: Quick Installation Guide

The following steps will help you install the Model 232CCXX Serial
Card. Please follow (step-by-step) the 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-static protective packaging:

• Discharge any static electricity build-up 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.

• 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-up and Troubleshooting – pinout, cable data, and

troubleshooting information. See Chapter 6 for more details.

Left-click on Interrupt Request.

Find a free IRQ in the displayed list. Any number that is seen on
the left hand side of this screen is an IRQ that is currently being
used. The object is to find a number of IRQ(s) that are not listed
and set your port(s) using those IRQ’s.

Left-click on Input/Output (I/O).

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.
