14 Series 979 ATV Transducer
All user access is through the 15-pin D-sub connector. See the RS-485
Command Set section for more information.
The POWER LED indicates when power is applied to the 979 ATV Transducer.
The FILAMENT ON LED indicates when power is applied to the transducer
filament. The FILAMENT ON light can also be used in conjunction with the
Test RS485 – TST command (described in the RS485 Command Set
section) to visually identify which sensor is set to a particular address. This is
useful when several transducers are connected to the same system.
The figure below shows the front view of the 979 ATV Transducer.
