RCom Installation Guide & User Instructions
Installation
Cabling
The basic requirement is to connect all the belt packs in parallel. Standard
microphone cable can be used between the belt packs, with pin 1 connected
to ground. The male and female connectors on the belt packs are simply
paralleled, enabling the units to be easily 'daisy chained' together.
Cable size
Standard microphone cable of 20/0.1, 7/0.2 or similar construction is
adequate for most installations of up to 10 belt packs and about 100m total
in length. For installation larger than this, heavy duty cable is
recommended. For installations of greater than 20 belt packs, special
considerations need to be made (please contact is for details).
Power supply
A single power supply is required, and only one must be used. The
recommended supply voltage is 12V DC, but anything up to 25V can be
used. The supply current is approximately 60mA per belt pack with both
LEDs illuminated.
The GreenHalse 12V 1200mA power supply is recommended for use
with the RCom, and can supply up to 20 units.
Headsets
Most headset types can be used with the system, and it is possible to switch
on a 2V bias voltage for use with electret microphones.
