The distance of the RB02 Radio Base Station and RPT1 Repeaters from the NCE command station will have a direct impact on wireless performance!  

If the RB02 is 30 feet or farther from the command station then the cab bus cables being used require a power injection to deal with cable loss. In addition any single run of cable between the RB02 and a repeater over 30 to 40 feet will also need additional power.

The overall goal is this:  A minimum of 8v DC as measured on the UTP Panel and cab bus cables between pins 2 and 5  / Black and Yellow.

Any combination of mismatched versions of our wireless products will cause issues. example  one cab with version 1.4  of the wireless and another with version 1.5.

The actual version does not matter as much as everything being on the SAME version. 

All cabs must be on SAME radio version no matter what that version is. Mixing versions will result in problems. The current version is 1.5b

Wireless CAB versions and release dates:

v1.3 2005

v1.4 2005
