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.

INSTALLATION

NOTE:

For the maximum
recommended cable dis­tances refer to the installa­tion manuals supplied with
equipment (camera, lens
and monitor) to be used with
the switcher.

TERMINATING SWITCHERS

1. Place the unit on a flat surface, or install it in an equipment rack using the appropriate
rack-mount kit.

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.

Table A. Video Coaxial Cable Requirements

Cable Type* Maximum Distance

RG59/U 750 ft (229 m)

RG6/U 1,000 ft (305 m)

RG11/U 1,500 ft (457 m)

* Minimum cable requirements:

75 ohms impedance
All-copper center conductor
All-copper braided shield with 95% braid coverage

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

IMPORTANT:

Looping
switchers do not have inter­nal termination. Inputs must
be terminated at 75 ohms by
other equipment in the
system.

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.)

NOTE:

Configuration does
not permit two-way commu­nication. Microphones or

Using appropriate cable with compatible connectors, connect audio signal sources to RCA
jack (refer to Figure 5).

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:

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.

Use Monitor 2 non-amplified output only when interfacing with the

IMPORTANT:

Units plugged into electrical outlets should be unplugged

before spraying contacts.
