Introduction
Overview
The PANACOM PMS8232 provides the PC with eight RS-232 asynchronous ports. The PMS8232 allows
for connection to any device utilizing the RS-232 electrical interface, such as modems, data-entry
terminals, and plotters.
What’s Included
The PMS8232 is shipped with the following items. If any of these items is missing or damaged, contact the
supplier.
•PMS8232 Serial I/O Adapter
•DB-68 to eight DB-9 ‘Spider Cable’
•Serial Utility Software
•User Manual

Card Setup
Clock Modes
The PMS8232 employs a unique clocking option that allows the end user to select from divide by 4 and
divide by 1 clocking modes. This mode is selected at J2,J3.
To select the Baud rates commonly associated with COM: ports (i.e. 2400, 4800, 9600, 19.2, … 115.2K
Bps) place the jumper in the divide by 4 mode (silk-screen DIV4).
Figure 1 - Clocking Mode ‘Divide By 4’
To select the maximum data rate (921.6K bps) place the jumper in the divide by 1 (silk-screen DIV1)
position.

Baud Rates and Divisors for the ‘Div1’ mode
The following table shows some common data rates and the rates you should choose to match them if using
the adapter in the ‘Div1’ mode.
For this Data Rate Choose this Data Rate
9600 bps 150 bps
19.2K bps 300 bps
38.4K bps 600 bps
57.6 K bps 1200 bps
115.2 K bps 2400 bps
230.4K bps 4800 bps
460.8K bps 9600 bps
921.6K bps 115.2K bps
If your communications package allows the use of Baud rate divisors, choose the appropriate divisor from
the following table:
For this Data Rate Choose this Divisor
9600 bps 96
19.2K bps 48
38.4K bps 24
57.6K bps 12
115.2K bps 8
230.4K bps 4
460.8K bps 2
921.6K bps 1
Address and IRQ selection
The PMS8232 is automatically assigned I/O addresses and IRQs by your motherboard BIOS. Only the I/O
address may be modified by the user.
Adding or removing other hardware may change the assignment of I/O addresses and IRQs.
Installation

Installation
Operating System Installation
Windows 95/98/NT
Run Setup on Disk 2 of the Serial Utilities Software.
Windows 3.1x
Refer to the Win3x.hlp file in the \Win31 directory on Disk 1 of the Serial Utilities Software.
DOS
Refer to the Readme.txt file found in the \DOS directory on Disk 1 of the Serial Utilities Software.
Other Operating Systems
Refer to the appropriate directory on Disk 1 of the Serial Utilities Software.
System Installation
The PMS8232 can be installed in any of the PCI expansion slots and contains a single jumper strap that
must be set for proper operation. Please see the Card Setup section of the manual for information on this
jumper.
1. Turn off PC power. Disconnect the power cord.
2. Remove the PC case cover.
3. Locate an available PCI slot and remove the blank metal slot cover.
4. Gently insert the PMS8232 into the slot. Make sure that the adapter is seated properly.
5. Replace the screw.
6. Replace the cover.
7. Connect the power cord.
Installation is complete.
Technical Description

Technical Description
The PMS8232 utilizes the 16C554 UART. This chip features programmable baud rate, data format,
interrupt control and a 16-byte input and output FIFO, and is functionally 4 16C550 UARTs. The 16C654
UART is also available on this card, which has a 64-byte FIFO as opposed to the 16-byte FIFO available
in the 16C554 and the 16C854 which has a 128-byte FIFO.
