TO SET THE VIDEO MODE AND TERMINATION
The videophone can operate with either composite video signal (coax cable) or balanced video signal (two wires). Switches 1 & 2 of
DSW2 are used to set video mode while switches 3 & 4 are for video termination.
VIDEO MODE DSW2
Switches 1,2 Mode
Coax
Balanced
75 OHM VIDEO TERMINATION DSW2
Switches 3,4 Termination
Enabled
Disabled
Switches 3 and 4 adjust the video signal impedance. when using more than one videomonitor in parallel (without a video
splitter) put both switches in the OFF position on all but the last videomonitor (end of line).
VIDEOMONITOR/INTERCOM ADDRESS, VIDEO MODE AND TERMINATION SETUP DSW1
Each intercom is addressed in binary (PHONE ID) using the 8 way dipswitches located on the rear of the unit. Each switch corresponds to one bit which can have a value 0 (OFF) or 1 (ON). Each bit corresponds to a decimal weight depending on the position:
Switch 1 = decimal 1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=128. I.E. to set the address 37, put switches 1, 3 and 6 on (1+4+32=37).
