2-4 × Serial ports in a single module.
Configurable for RS232/422/485 modes.
The COM4 module features 2 to 4 serial ports (depending on modes configured), each with fully configurable serial port options.
Choose your port modes:
RS232/422/485
Configure each port to operate in your required serial port mode. Up to 4 ports of RS232 without flow control.
Need more serial ports?
Just get another module.
The beauty of the modular controllers is their flexibility. Need more of a specific port? Get another module and plug it in.
Fully configurable.
Baud rates, flow control, etc.
Each port can be fully configured with a wide range of baud rates, flow control options, stop/start bits, parity, and so on.
Overview
The COM4 module features 2-4 user configurable serial ports, and comes with spring terminals for quick and easy, yet secure connections to control external serial devices. Plug it into a modular controller to add serial port control to your system.
Notifications
The COM4 can be setup to send notifications of incoming data per port. Notifications can be sent as a broadcast to all CFLink devices, to specific CFLink IDs or both.
Passthrough Modes
Any device on the CFLink network, including the COM4 module, can be configured to passthrough their incoming and outgoing data to the LAN Bridge, for direct Ethernet access (TCP or UDP).
Serial Port Modes
The number of available serial ports depends on the modes they are configured in. For instance, 4 separate ports can be defined for RS232 without flow control. But only 2 ports can be configured if both set to RS485.
