COM Ports (COM1 & COM2)
POC-100 provides two COM ports on the back panel for communicating with external
devices. COM1 and COM2 are located on the back panel via 9-pin D-Sub male connectors.
They are implemented using industrial-grade ITE8783 Super IO chip (-40 to 85°C) and
provide up to 115200 bps baud rate.
COM1 is a software-selectable RS-232/422/485 port and COM2 supports RS-232 only. The
operation mode of COM1 can be set in BIOS setup utility (refer to section 4.1 for detail).
The following table describes the pin definition of COM ports.
