This jack is set at the factory to provide bias voltage for electret mics, though a setting for a dynamic mic may also be 
selected,.  
NOTE: Due to their design, use of multiple mobile phone type headsets in a system could adversely affect 
nulling, crosstalk, and overall system performance. 
External Setup Connector
 
This 3.5mm connector is located on the side of the beltpack, just below the Setup button.  It sends and receives RS-
232 data for advanced programming with a PC running V-Pack
TM
 software.  The VPC-1 cable or equivalent is 
required for connection from the PC to this jack.  The VPC-1 is a DB-9 female to the tip-ring-sleeve 3.5mm plug.   
Contact your dealer or the Clear-Com factory for info about obtaining a cable.

5. Setup 
Your RS-600 Series beltpack can be changed from the factory default settings in one of two ways: with a PC or on the 
beltpack itself. Different Setups can be stored in the beltpack’s on-board memory.  Setup from a PC is better if you 
need access to the full range of available feature options or if you are setting up multiple beltpacks.  On-board Setup 
is convenient if you need to make a quick change to one or a number of beltpacks and/or a PC computer is not 
conveniently available. 
For PC Setup, you must first install the V-Pack
TM
 software on your PC.  Once installed, connect the beltpack to the 
computer’s serial port.  The beltpack end requires a 3.5mm (1/8”) plug.  The other end is a DB-9 female. The cable 
must be capable of carrying RS-232 data. Clear-Com offers this cable as the VPC-1. Note that the beltpack needs to 
be plugged into an active intercom line (for termination) and receiving 12-32V DC power.  This can be from the 
intercom system or a stand alone power supply or main station. Connect the beltpack to the PC. 
Open the program and make your selections.  If using a custom configuration for multiple beltpacks, use Beltpack 
Cloning to upload the selections to multiple beltpacks (one at a time). 
For more detailed instructions on use of the software, see the V-Pack
TM
 manual. Both the software and manual can 
be downloaded free from the Clear-Com Web site.  A factory CD-ROM is also available for purchase through your 
dealer or direct from Clear-Com. 
Onboard Setup
 
For onboard Setup, the beltpack can remain plugged into the system.  Onboard Setup allows you to select one of four 
Modes for the beltpack and to alter a number of specific parameters or Options. Mode 1 is the default for the 
beltpack. 
All four modes have similar settings from the factory, though some slight variations are included.  These can be edited 
and saved.  The beltpack will store these configurations in non-volatile memory until they are changed or the beltpack 
is reset to factory default.
