Why choose AMX CE-COM2 Control Extender - 2 RS232 Ports
- ✓ Two independent RS232 channels with mixed terminal types (5-pin and 10-pin)
- ✓ Supports RS232/422/485 protocols for broad legacy device compatibility
- ✓ Baud rates from 300 to 115.2K with hardware flow control (XON/XOFF, CTS/RTS)
- ✓ Native HControl auto-discovery streamlines AMX processor integration
Why choose AMX CE-IO4 Control Extender - 4 IO Ports
- ✓ Four configurable ports handle analog inputs (0–10 VDC), digital inputs, and digital outputs in one unit
- ✓ Digital outputs source or sink 100mA, enabling direct relay and sensor control
- ✓ Includes 12 VDC power output for external devices, reducing adapter needs
- ✓ Extremely low power draw (1.9W) fits easily within standard PoE budgets
Frequently asked questions
Which unit should I choose if I have older serial-controlled equipment?
The CE-COM2 is purpose-built for legacy RS232 integration with two independent serial channels, RS232/422/485 support, and configurable baud rates. The CE-IO4 handles analog and digital signals but is not designed for serial device control.
Can either unit control relays or sensors directly?
The CE-IO4 excels at this with digital outputs capable of sourcing/sinking 100mA plus integrated 12 VDC power output for external devices. The CE-COM2 is limited to serial communication and requires the connected device to handle relay or sensor logic.
How do these differ in physical footprint and installation?
Both are compact with small cable footprints. The CE-COM2 uses screw terminal connections (5-pin and 10-pin 3.5mm), while the CE-IO4 uses a six-pin terminal block, so check your rack space and available connectors.
Do both support PoE power, and what about power requirements?
Both support Gigabit Ethernet with PoE power delivery, eliminating separate power supplies. The CE-IO4 draws only 1.9W, while CE-COM2 power consumption is not specified but should remain well within standard PoE budgets for a serial bridge.
