2 WAY DIP-SWITCH (SW2)
The two way dip-switch adjusts the impedance of the video signal. The default setting is “ON” for both
switches (75 Ohm): when there are more videophones in parallel connection (without video distributor)
both switches must be “ON” only on the last videophone (looking at the connection order) while for all
other videophones both switches must be set to “OFF”.
