ZAXNET MENU 

 

ZaxNet Mode 

 

 

 

 

 

This menu sets the mode of the ZaxNet transceiver. 

 

OFF

 - The ZaxNet transceiver is disabled. The TRX745 will not receive ZaxNet commands or time code and it 

will not send any ZaxNet audio. Please note if ZaxNet mode is set to OFF only the group and unit code menu 

will be accessible. 

 

RX 

- The ZaxNet transceiver will receive ZaxNet commands and time code. This screen will display what 

ZaxNet data is being received by the TRX745. Including total received information packets, ZaxNet TC 

received and remote control commands received. This information is used for debugging purposes. 

 

TX 

- The ZaxNet transceiver will send ZaxNet confidence audio and time code. Please note that in ZHD48 

mode the TRX745 will not be able to go into transmit mode. 

 

ZaxNet Receive Frequency Set 

This menu will only appear if the TRX745 is set to receive (RX) mode

 

 

 

 

 

The ZaxNet receive frequency is the frequency that the TRX745 will get its wireless time code and remote 

control commands on. This frequency will need to match the frequency of the corresponding ZaxNet 

transmitter. The ZaxNet transmitter can be a QRX with QIFB, Nomad, TRX900CL or IFB100/200. The TRX745 can 

also receive ZaxNet time code from another TRX transmitter or a ZFR recorder that is transmitting ZaxNet on 

this frequency. Please keep in mind that the range will be limited when receiving ZaxNet from a TRX or ZFR. 

When the TRX745 is receiving a valid ZaxNet signal the signal strength will be shown as well as signal strength 

meter that runs vertically on the far right side of the screen. 

 

ZaxNet Transmit Frequency Set 

This menu will only appear if the TRX745 is set to transmit (TX) mode

 

 

 

 

 

The ZaxNet transmit frequency is the frequency that the ZaxNet transmitter on the TRX745 will broadcast time 

code and confidence audio on. Please note the ZaxNet transmitted audio is for quality control purposes and the 

expected range will be less than 20 feet. 

 

 

ZAXNET MODE: TX 

 

RX FREQ : 2.403 RX 

SIGNAL : 28 

ZAXNET TX FREQ: 

  2.473
