Termination Switch
The MS-500 has two different termination options. Normally this switch is set as “ON”. In PL intercom
system has only one termination point. If there is more than one base station in the system, the
termination point should be at main control station. Set the main control station’s termination switch as
“ON”, and other station’s termination switches as “OFF”.
When this switch is turned to ON position, one 220 ohm termination resistor will be connected to
intercom line. If the intercom system is not terminated, the level of intercom line will be too high, and
the system stability will be influenced. However, only one termination point is allowed within same
intercom line. If multiple termination points are used incorrectly, the driving load will be aggravated, and
the level of intercom line will be too low.
This switch is set to ON position by factory default. Before using, you should set it to ON or OFF position
according to the actual connection of intercom line.
Notice:
One system only allows one termination point, multi point is not allowed. Otherwise, the system will
be overloaded.
