C.1
Board description
On the CP321 it is possible to utilize a transition module which provides optoisolated RS232
functionality for the SER0-Interface. All signals for utilizing hardware handshake protocol are
available in optoisolated form.
Supported Signals
The following signals are provided by the CP320-TR2:
• TxD - Transmit Data
• RxD - Receive Data
• RTS - Request to Send (used on PC based systems for hardware handshaking)
• CTS - (used on PC and Kontron systems for hardware handshaking)
• DTR - (used on Kontron systems for hardware handshaking)
The board itself is available in the E2 temperature range.
Users who require a CP321 with an opto-isolated serial interface are supplied with a custom-
ized CP321 on which the standard RJ45 connector is omitted (SER) and also with this module
which comes with a substitute RJ45 connector routed through optoisolation circuitry on the
module.
The module has been designed so that it does not increase the board width, which remains
unchanged at 4HP with the module in place. View of Underside of the CP320-TR2 Module.
