Supports RS-232 and RS-485/422, including four-wire full-duplex and two-wire half-duplex operation.
Product Overview
IC695CMM002 expands the serial communication capacity of a PACSystems RX3i controller with two independent, isolated ports. Each RJ45 port is configured in PAC Machine Edition for its electrical mode, framing and application protocol.
The two ports can serve different supported protocols except where the DNP3 operating rules require both ports on the module to remain within DNP3 master or slave service.
Performance
Offers serial rates from 1200 to 115200 bps with configurable parity, data bits and stop bits.
Supports Modbus master/slave, CCM slave, DNP3 master/slave and Serial I/O functions by firmware level.
Allows up to six serial communication modules in the main RX3i CPU backplane.

System Integration
- Export every port’s electrical mode, protocol, baud, parity, data bits, stop bits, station address and timeout.
- Photograph the RJ45 pinout adapters and label each shield, termination and multidrop branch.
- Verify firmware against protocol needs, particularly DNP3, CCM and any hardware-flow-control behavior.
- Include both 3.3 V and 5 V demands in the RX3i backplane power calculation.
- After replacement, test request and response traffic, timeout handling, diagnostics and recovery for both ports independently.
Applications
- Modbus RTU master or slave links to drives, meters and process instruments.
- DNP3 serial communication where the complete module protocol restriction is acceptable.
- ASCII or Serial I/O exchange with printers, scanners and proprietary devices.
FAQ
Why can one healthy port on IC695CMM002 work while the other does not?
Each port has independent electrical and framing settings; cable pinout, termination, address or protocol mismatch can affect only one channel.
What firmware information is needed for IC695CMM002?
Provide the complete module label and firmware because CCM, DNP3 and hardware-flow-control behavior varies by release.
Can IC695CMM002 run DNP3 on one port and Modbus on the other?
The documented DNP3 rule requires the other ports on the module to be configured only for DNP3 master or slave when any port uses DNP3.
What should be recorded before replacing IC695CMM002?
Save both port configurations, adapter pinouts, shield and termination locations, peer addresses, timeouts and representative message traces.
How should intermittent IC695CMM002 RS-485 faults be isolated?
Check polarity, bias, termination at the two physical ends, shield reference, duplicate addresses, turnaround timing and baud/framing consistency.
