7. 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.
7-1. Serial Interface
Crosspoint switchover and tally output can be controlled via the SERIAL ports on the MFR
Series main unit or MFR GPI.
7-2. 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.

Crosspoint Remote Control using ASCII code.
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 repond to commands.
