EM 122

RX transducer cable from Preamplifier to TRU

This one to one cable is used from the EM 122 Preamplifier to the Transceiver Unit.
Each cable is terminated at the cabinet's rear through a 50–pins “D-sub” connector.
The cables are supplied by manufacturer.

Apply a label to the cable marked with module type (RX) and the cable registration
number (both ends).
