A complete list of the physical board interfaces of all board variants is given in the fol-
lowing table:
T/M = Transition module
1.2.3 Transition Module
The transition module CP345-TR1 which connects to the optoisolated board variant
mainboard provides the optoisolation, serial I/O transceivers and external interfacing
connector of this board variant. Its own transition module interface connector CON2
(male) is mounted to the mainboard transition module interface connector CON3
(female) and is fixed using two stand-off bolts thus building a single unit.
The size of the transition module (53mm x 91mm) is such to allow the placement of four
modules on a possible 6U serial I/O controller board.
1.2.4 Rear-I/O Modules
The non-optoisolated board variant allows for the installation of a rear-I/O module. If a
rear-I/O module is used, the frontend signals are mirrored to a J2 rear-I/O connector.
Two variants of the CP345 rear-I/O module can be installed:
• Non-optoisolated
• Optoisolated
The two variants of the rear-I/O module differ in terms of their interface connectors (see
table above).
1.2.5 Frontpanel Adapters
The non-optoisolated standard variant of the CP345 serial I/O board is provided with a
serial I/O connector block (four RJ45 connectors). Each of the RJ45 jacks is dedicated
to a single serial I/O channel. In order to comply with standard PC interface technology,
a single-channel RJ45-to-D-Sub frontpanel adapter (CP-ADAP-RJ45-D5009/PC) can
be connected to the frontend interface of each channel. This adapter terminates on the
user side with a 9-pin male D-Sub connector which includes the signals of the relating
channel.
