Introduction
Introduction
Overview
The Sealevel COMM+232.PCI is a two channel PCI Bus serial I/O adapter for
the PC and compatibles. It provides two RS-232 serial ports supporting data
rates up to 460.8K bps.
The COMM+232.PCI works seamlessly with the standard operating system
serial driver. UART upgrades are available providing 32. 64 and 128 byte
FIFOs.
What’s Included
The COMM+232.PCI is shipped with the following items. If any of these items
are missing or damaged, contact the supplier.
• COMM+232.PCI Serial I/O Adapter
• Sealevel Software
Factory Default Settings
The COMM+232.PCI factory default settings are as follows:

Address and IRQ selection
The COMM+232.PCI 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.
Clock Modes
The COMM+232.PCI employs a unique clocking option that allows the end
user to select from divide by 4 and divide by 1 clocking modes. These modes are
selected at Headers E1 and E2.
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) position.

Baud Rates and Divisors for the ‘DIV1’ mode
The following table shows some common data rates and the rates you should
choose if using the adapter in the ‘DIV1’ mode.
For this Data Rate Choose this Data Rate
1200 bps 300 bps
2400 bps 600 bps
4800 bps 1200 bps
9600 bps 2400 bps
19.2K bps 4800 bps
57.6 K bps 14.4K bps
115.2 K bps 28.8K bps
230.4K bps 57.6 K bps
460.8K bps 115.2 K 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
1200 bps 384
2400 bps 192
4800 bps 96
9600 bps 48
