Introduction
Overview
The COMM+16.PCIe provides sixteen RS-232 asynchronous serial ports capable of data rates to 460.8K
bps. Each RS-232 port implements all modem control signals for maximum compatibility with a wide range
of peripherals. The board is PCI Express X1 compliant and can be used in any x1, x2, x4, x8, or x16 PCI
Express slot. The board utilizes 16C854 UARTs to provide 128-byte Tx/Rx FIFOs for maximum reliability in
data intensive applications. Standard operating temperature range is 0°C to 70°C and extended
temperature range (-40°C to +85°C) versions are available.
The board ships with two 36" ‘spider’ cables that terminate to a total of sixteen DB
-25M connectors (Item#
7161e) or sixteen DB-9M connectors (Item# 7161e-DB9). Additional ordering options allow the choice of
UARTs for custom baud rates and 9-bit protocols.
The COMM+16.PCIe is designed to be used with a variety of operating systems including Microsoft
Windows and Linux. Sealevel’s SeaCOM software uses t
he standard Windows WIN32 API and eliminates
proprietary DLL files. This allows Sealevel SeaCOM software to maintain 100% compatibility with Microsoft
Windows applications. SeaCOM software also includes sample code and utilities to simplify application
development.
