Installing the Station Transponder Units on Site
108 025-9581M
• An oscilloscope (and/or a Radio Service Monitor) is used for level setting, for RF-
based interfaces, a Radio Service Monitor has the added benefit of sensing
deviation
• A PC or laptop with a terminal program and a serial port, Windows XP includes
HyperTerminal, the terminal program is required to configure user-programmable
parameters and a serial port is required to complete the data connection, a
programming cable, Zetron part number 709-7208, completes this item
• A second person is required for audio level alignment at the Station Transponder
Unit, one person works at the dispatch console and the other in the remote Station
Transponder Unit, having two people is the most efficient method of setting the RX
and TX levels
Opening the Case
During installation the Station Transponder Units must be opened to enable access to the
mounting holes in the rear of the chassis, and later, to enable power connections, PA audio
and other miscellaneous connections, and level settings to be made.

Opening the Model 6203
1. If it is not already mounted on a wall, lay the unit on its back on a convenient work
surface.
2. Loosen the two retaining screws located at the top of the faceplate. These are
captive screws, so they do not need to be removed to open the unit.
3. Grasp the outer cover at the top of the faceplate and fold the unit open around the
hinge at the bottom of the unit. If the unit is already mounted on a wall, be careful
prevent the front panel from just falling open and striking the wall below the unit.
4. When you have completed the task for which you opened the unit, close the front
cover and tighten the two screws at the top of the faceplate.
Mounting the Case
The Model 6203 is designed primarily for wall mounting in a vertical position. There are
four standard screw-mounting slots in the back corners of the case for securing it to a wall.
Standard conduit knockouts are provided in the bottom and back for the connection of
permanent power, control and communication wiring. Alternatively, a stand can be built
for vertical desk mounting, or the unit can be mounted horizontally.
