Figure 12: Wire Line System Configuration Menu
The reason this mode must be used on “star” network wire line systems is because Model
6s cannot hear other Model 6s when they transmit, only the Model 26. In all other
communications modes the Model 6s may transmit unsolicited. When using these other
modes, they listen to see if the line is clear to prevent transmit collisions.
VOX Communication Mode
This communications mode is designed for use with a conventional radio interface where
the Model 26 uses its own circuitry to detect channel availability. If the Model 26 detects
noise above a threshold, set by the VOX potentiometer, then it thinks the channel is busy
and will not transmit. If this mode is selected, the COR Input Pull-up jumper must be in
the “B” position (10 kΩ pull-up), the VOX Control jumper must be in the “A” position
(enable) and the COR input should not be connected to any active signal (refer to
Hardware Jumper Settings on page 19).
