Remote Control [7.5]
Planning [7.5.1]
As a general guide for basic system design planning purposes, the following may help you in your
equipment requirement and selection process. Review Figure 1 for a summary of the pros and cons of
each system.
REMOTE
BENEFITS
DOWNSIDE
Local Extension Control:
•
Less expensive controllers
•
Distance limited (<1K ft)
•
Hard to add controllers
•
Requires special expensive cable
between each controller and radio.
•
NO remote frequency selection
•
Requires tools and technical skill to
connect wires to a terminal board.
Tone Remote Control:
•
Not distance limited
•
More expensive controllers
•
Easy to add controllers
•
Requires a tone remote adapter
•
Uses low cost phone wire to
connect between adapter and
radios.
•
Allows remote frequency selection
•
No tools required to install units.
Figure 1 - Comparison between Remote Control Systems
NOTE: As the engineering work for the Local Extension Controllers has not been completed, it is recommended
that the tone remote is selected if at all possible as the remote interface option. If a Local Extension Controller is
desired for cost reasons, the engineering work will be completed at that time but please be aware that the radio
will take longer to get out the door.
Installation [7.5.2]
The M2115B and M211B-XX have two different styles of connectors for remote interfaces: The M2115B provides the
connections necessary at the rear panel 12-pin power plug using a custom connector for connecting/disconnecting from
the remote interface, while the M2115B-XX series radios have a 25-pin connector on the back of the radio that the tone
remote interface connects to directly. This plugs for each radio contains all the connections needed for connecting
various types of remote controllers to allow remote users to operate the M2115B base station radio.
Each basic remote control type requires a different adapter cable to connect between the radio and the controllers. There
are four basic styles of controllers available for connecting to the M2115B, they are:
1. Telephone style handset
2. Desktop style with a pedestal style desktop microphone
3. Hands free voice operated transmit (vox) box
4. Dispatch style controller with a gooseneck microphone
