Board Location in the System

Board location within a system must be considered carefully. Depending on the number of
CP345 boards, their locations in a given system and the operating system being used, appli-
cation programs may have difficulty to identify boards properly. In particular, when configura-
tion changes such as board replacement, movement to another slot etc. are made after the
initial system implementation. Therefore, any changes made to a system should be carefully
considered before making the change, and proper operation be verified before the system is
put into operation again.
Note...
When configuring a system it is recommended that all boards to be
used first be installed in the system prior to installing any drivers or
other board related software. Failure to do so may result in the non-
identification of a given board or boards.

Cabling

3.1.2.1 Four-Channel Frontpanel Adapter

In order to provide separate serial I/O channelling, a four-channel frontpanel adapter
(CP-ADAP-CP345-DSUB50) can be connected to the 50-pin frontend connector of the optoi-
solated variant of the CP345 mainboard (CP345-OPT) or the optoisolated rear I/O module
(CP-RIO-345-OPT) of the rear-I/O capable board (CP345-RIO). This adapter terminates on
the user side with four male 9-pin D-Sub connectors which include the signals of channels 0 to
3. The adapter cables have a length of approx. 15 cm.
The pinouts of the adapter's 50-pin and 9-pin DSub connectors are shown in the Functional
Description chapter of this manual.
