Important Notes
New Units
The Model 4010 Communication Console you have received is fully functional and
calibrated to a factory standard of 0 dBm for both RX and TX levels. The line terminations
are set at low impedance (600
Ω
). You will need to reset RX and TX levels for the radio
types and wiring configuration at each site.
It is important to set the impedance of the audio lines to high when connecting the channel
card audio lines in parallel with another 4010 system or remote unit. One device remains
at low impedance (600 ohm) and the remainder are set to high. See
on page 26 for setting the termination jumpers.
Program/Run Switch
The Model 4010 is programmed by sending a configuration file to it from a PC over a
temporary serial connection. The configuration data is stored in write-protected memory,
so writing must first be enabled by the program/run switch located on the bottom of the
unit. Do not move this switch unless programming or checking the options in the 4010. On
a desktop Model 4010, this switch is located on the bottom of the unit. The "normal" or
"run" switch position is to the right (towards the Unselect speaker). Detailed programming
instructions are provided in
Physical Installation
Console Location
When preparing to place the control panels, consider the amount of tabletop space
required not only for the console, but also for a writing surface for the operator. Also,
consider where accessory items such as microphones, foot switches, and headset jack-
boxes may be placed. Another consideration is how close the placement will be to a power
outlet. A solid earth ground must be provided.
Console Access
The channel connectors of the Model 4010 Console and option wiring are accessed from
the rear of the unit. Routing of the channel wires to the common connector block must be
considered. The rear of the unit also has the channel status lights, which need to be
monitored during system verification and troubleshooting. To gain access to insert channel
cards or to make channel or console adjustments, the top of the desktop console is opened
in a clamshell fashion that requires about 17 inches of vertical space. A service loop on the
