NOTE:
All of the diagrams in this chapter show the solder side of each connector.
ZFR100 cables
NOTE:
The following 3-pin micro-LEMO connectors mate with the microphone connector:
FGB.00.303.CLAD.22 – has a latch with a pull release. (HIGHLY recommended for RFI prevention)
FVB.00.303.NLA
– has a latch with a twist release.
CAUTION:
When wiring a microphone for the TRX900 ( /AA), the microphone shield/ground must be
connected to the LEMO shell as well as the correct pin on the microphone connector itself.
This connection stops RF energy from entering the body pack through the shield of the microphone cable. If this
happens, the user can experience RF dropouts at any distance from the receiver. Routing the microphone
cable away from the TRX900 antenna is a temporary fix if this effect is noticed.
Use of the push-in type LEMO connector, rather than the screw in type, is advised as it is easier to make the
ground connection to the connector shell.
