Ethernet OEM Module Crestron eServer™
COM IN
This 9-pin connector (DB9F) is used as a pass-through for device control. This
bidirectional serial port is used for RS-232 communication. It can also be used for
configuring the device with IP address, mask, etc.
NOTE: This port is also known as the Console (Main) port in some setup menus
discussed in "port" on page 15.
NOTE: The pinout of each 9-pin port is non-standard (refer to table after this note).
This may result in a conflict with some equipment and therefore do not use all nine
pins. Only the required pins for each communication type should be connected.
