DESCRIPTION  
The MS500 Series provides an inexpensive and reliable method of switching 4 to 18 inputs  
to a single monitor output using interlocked manual pushbuttons. Included in this series is  
the MS540 switcher with two monitor outputs and the capacity to switch up to 40 inputs with  
a 14 pushbutton panel.  
The MS500 Series Switchers are designed for either looping or terminating operation,  
depending on the model.

2. Refer to Figures 1 - 6 and select the desired configuration for your installation. Make  
all equipment connections as illustrated in the drawings. Refer to Table A for the type  
of coaxial cable to use.  
3. Plug in the power cord. The switcher will begin operating.

TERMINATING SWITCHERS  
When using non-looping switchers, the monitor should be terminated unless the looping  
output, if available, on the monitor is used. (Refer to Figures 1 and 2.)

LOOPING SWITCHERS  
Use coaxial cable to connect the input and looping video cables to the appropriate input  
connectors. Connect the monitor(s) to the monitor output. (Refer to Figures 3 and 4.)  
IMPORTANT: Looping  
switchers do not have inter-  
nal termination. Inputs must  
be terminated at 75 ohms by  
other equipment in the  
system.

SWITCHERS WITH AMPLIFIED OUTPUT  
The MS540DT and MS540LDT switchers provide both an amplified output (Monitor 1) and  
a non-amplified output (Monitor 2). Most installations require the use of Monitor 2 output for  
proper operations.  
NOTE: Use Monitor 2 non-amplified output only when interfacing with the  
MPT9000CZ/MPT9000PZ or KBD9000/KBD9000-X Coaxitron controls.  
OPERATION  
To operate the MS500 Series Switcher, plug in the power cord and press a camera button  
to view video from the corresponding camera.  
MAINTENANCE  
Regularly scheduled maintenance is not required. However, maintenance may be required  
in the following situations:  
1. For switcher contacts that are not conducting properly, clean with a non-conducting  
electrical contact spray cleaner especially made for that purpose. Remove cover for  
access to the contacts and spray cleaner carefully into contacts from the rear.  
2. To replace burned out bulbs in illuminated models, remove the switch cover from the  
front of the unit and push the bulb upwards, then lift out. Replace with Pelco #LAP327.  
IMPORTANT: Units plugged into electrical outlets should be unplugged  
before spraying contacts.
