MultiDyne FMX-125 - Manual (Page 7)

Instruction Manual, FMX-125 SPECIFICATIONS 7
5. Screw terminals for contact closure control inputs. Apply TTL logic 1 to close relay.
6. Screw terminals for the 8 dry contact closures. The contact closures are to a common
return, which is floating.
FMX-125 SETTINGS
The front panel of the FMX-125 has level adjustments for the 2 audio channels. These are for
receiver audio output level. Adjust to personal taste.
There are dip switches to set the data protocol for each of the 12 data channels. Set the
switch for each channel to either RS422/485 or RS232. Be sure the termination jumper
selections on the breakout board are consistent with the switch settings on the FMX-125
connected to it. Normally, for a given channel, you would select both ends of the link to have
the same protocol, but this is not necessary if you want to use the link to convert from one
protocol to another.
MOUNTING, POWER and INSTALLATION REQUIREMENTS
The fiber optic system dissipates a significant amount of heat due to the high-speed
circuitry and optics. The units should have adequate ventilation. The units are powered by a
desktop universal-input supply.
