6. Serial / LAN Command Control
Up to 20 external devices can be connected to an MFR Main Unit (including MFR-GPI serial ports)
through LAN or serial interface.
6-1. Serial Interface
Crosspoint switchover and tally output can be controlled via the SERIAL ports on the MFR Series
main unit or MFR GPI.
6-2. LAN Interface
The MFR Series main unit is able to connect to a third-party automatic control system via the RJ-45
port (PC-LAN port). The TCP/IP communication protocol is supported. The control PC will be the
Client, and the MFR Series main unit will be the Server.

Command protocol
Crosspoint Remote Control protocol
* When a redundant CPU is configured, a client should connect to both LAN ports (PC-LAN CPU1 and
PC-LAN CPU2) and send commands to the ports respectively. When the system functions normally, the
secondary port (PC-LAN CPU2) do not respond to commands. But if an error occurs in the CPU1
system, the secondary port will take over the primary port and respond to commands.
