Dual Display

For a dual display configuration a 4-Pin Y-cable (FRC P/N XE-XXDLY4-C1A) 

is connected to the signal interface module 4-Pin connector. Two display extension 

cables (FRC P/N XE-FD7DISP2-C10A) and two display modules can be connected.

The 6-Pin connector from 

the display module is wired 

to the signal interface 

module 4-Pin connector. 

The two buzzer wires are 

pig-tailed off.

2—Power is supplied to the 

display unit from the signal 

interface module.
