The interface expansion unit lineup includes 3 types to suit your specific application. The number of units that can be connected is a maximum of 128, including the remote control units.
- MFR-GPI: GPI Unit

Provides an interface for GPI control. This 1 RU sized unit is equipped with user-assignable GPI/O (128 channels) and 4 serial ports (9-pin D-sub male). It can be used for setting Input/Output and supports system configuration.
- MFR-TALM: Tally Manager

MFR-TALM is a device for performing central management of tally and material names of the MFR main unit and peripheral devices (such as video switchers and multi viewers). MFR-TALM performs the tally calculation, which were originally performed by the MFR main unit, so that the tally linking can be speeded up.
- MFR-RULINK: MFR Remote Relay Unit

The MFR-RULINK connects MFR main units to MFR remote control units that are located in distant locations. Operations such as Cross point switching or Lock can be performed with MFR-RULINK using MFR remote control units from a distant location. (MFR-3100EX/5100EX/5000/8000 supported)
Supports Combinations of Multiple Remote control units
Multiple remote control units can be combined to make them function as a large scale control panel.
- Combination example:

For 128 x 128 full control + system settings:
MFR-40RU x 4 + MFR-39RUA x 1
System linkage with other products for flexible system operation
MFR series can be linked with other products including FOR-A video switcher HVS series or multi viewer MV series via LAN or serial port.
- MFR routing switcher crosspoints can be controlled from HVS video switchers.
- Integrated management of source names by MFR, which automatically send source names to HVS and MV multi viewers.
- HVS and MFR exchange tally information with each other.
- Source names and tally linkage between MFR and MV are controlled by TSL protocol. Support varies by model and function. For details, contact your FOR-A dealer.
