1.2 Board Overview
1.2.1 Board-Specific Information
The CP346 is a 4-channel serial I/O device supporting the RS232, RS422 and RS485 industry
standards. Three board variants are currently available, a non-isolated standard version, a
non-isolated variant provided with rear I/O connectivity, and an isolated variant. The external
interfacing of the board is accomplished using a 37-pin row D-Sub connector.
• 32-bit CompactPCI board, 33 MHz
• Up to 115.2 kBaud asynchronous transmission
• Isolated or non-isolated board variants
• 4 independent serial channels
• One 37-pin, dual row, D-Sub connector
• RS232, RS422, and RS485 standards
• Each channel individually configurable per hardware/software
• Bus termination resistors (RS422/RS485) hardware selectable
• Control LED’s on the front panel
• Rear I/O-capable board variant
• Windows® 2000, Windows® XP, Windows® XP Embedded, Linux® and VxWorks®
drivers
1.2.2 Board Variants
Three different variants of the CP346 main board are available:
• Non-isolated standard version
• Non-isolated version providing rear I/O connectivity
• Galvanically isolated version
All board variants have in common four individually programmable RS232, RS422 or RS485
channels. However, the external interfacing is realized via different physical schemes. The var-
ious board variants are equipped with one of the following connectors:
• Front panel connector
• Rear I/O connector
The front panels of the board variants are different in terms of their external interfacing.
A complete list of the physical board interfaces of all board variants is given in the following ta-

1.2.3 Rear I/O Modules
The CP346 board allows for the installation of a rear I/O module. On the CP346 rear I/O capa-
ble board variant, the TTL serial signals are routed to the J2 rear I/O connector.
