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-422 or RS-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-485 Mode, 115.2K
baud in RS-232 Mode
16550A UARTs on all ports
RS-232 mode supports lines: TD, RD, RTS, CTS, DSR, DCD, and
DTR
RS-422/RS-485 mode supports lines: TD and RD
RTS control of RS-485 driver enable
Can be wired for half or full duplex RS-485 communications

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.
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.
• 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.
CAUTION: Electrostatic Sensitive Device.
Use ESD precautions for safe handling.

B&B Electronics Ltd – Westlink Comm. Pk – Oranmore, Galway, Ireland – Ph +353 91-792444 – Fax +353 91-792445
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.

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.
