• When ZaxNet is set to receive (RX) this connector will output the ZaxNet received audio.
4. Time Code In/ Out - 3.5mm TRS (available with the QIFB option).
This connector will input or output time code depending on how the cable is wired. Please see the wiring
diagram section of this manual.
5. Serial Loop -The USB style connectors on the back of the QRX allow multiple QRXs to share a single
common QIFB option. For example one master QRX with a QIFB option board can be connected to 3 QRXs
with no option boards. The QRXs without option boards will behave as if they have an IFB option board
and will send remote control commands over the serial link to the master QRX.
Please note the USB connectors are NOT generic USB connectors that can be used as a connection to any
computer. These are used to exchange RS-422/RS-485 commands and a special cable is required to do this
please see the wiring diagram section of this manual for more information.

REMOTE POWERMODE
0: POWER = ON
The remote power mode menu allows for the RF power setting of the transmitters to be adjusted.
The transmitters have three selectable power settings:
• NORMAL - The transmitters are at full power.
• WAKE - If a transmitter is set to REMOTE STANDBY it will power up to a non-transmitting low power mode
that will use approximately 25% of the power of normal operations. A wake command will bring that
transmitter to full power.
To use wake mode set the transmitters BOOT UP MODE to REMOTE STANDBY. Then when the transmitter
powers up, it will remain in standby mode until it receives the wake command to bring it to full power. Once
the transmitter is awoken the only way for it to go back into standby mode is by power cycling the
transmitter.
• LOW 2 - Low 2 disables the RF power amplifier, RF board and microphone pre-amp on the transmitter. In
LOW 2 mode the transmitter will save approximately 50% of the power of normal operations. A transmitter
can be put into or taken out of LOW 2 as often as desired when selected in this menu.

IFB Mode Set
IFB MODE: TX
This menu sets the state of the ZaxNet transceiver.
• RX - The QIFB will receive ZaxNet IFB audio and time code.
• TX - The QIFB will send ZaxNet commands, IFB audio and time code.
Please note that any time this parameter is changed the QRX will need to be power cycled to initialize the IFB
board. Also note that when IFB mode is set to transmit (TX) a 2.4GHz antenna needs to be attached to prevent
unwanted RF from potentially interfering with the UHF reception.
Group ID Set
GROUP ID=1
The group ID sets the QIFB to a ZaxNet group. This allows the QRX235 to control a specific group of transmitters
without affecting others. So for example a QIFB set to Group 1 will control all transmitters set to group 1 and a
QIFB set to group 2 the QIFB will control all transmitters set to group 2. Most users will leave the group set to 1
on all products. Group codes can be set from 1 to 99.
IFB Voting Enable
This menu is only available when the IFB MODE is set to receive (RX)
NORMAL (OFF)
2 TXERS (ON)
IFB voting allows the QIFB to choose and switch to the stronger signal from two different ZaxNet IFB transmitters.
So for example on a large set a second IFB transmitter can be placed at a different location and the ZaxNet
receiver in the QRX235 will choose the strongest signal. Please note that the QIFB IFB voting feature sets the
second receive frequency as the current frequency +2. So for example if using IFB voting and the first frequency is
set to 2404 the second transmitter frequency should be set to 2406.
Updating the IFB Software
This menu is only available when the IFB MODE is set to Receive (RX).

Time code jam mute sets the length of time that the time code output is muted whenever a time code jump is
detected. So if there is a change in time code the time code out of the QRX235 will be muted for the time set in
this menu. This simulates removing the time code completely from a device and plugging it back in so that the
receiving device recognizes that there is new time code. This was added to help the RED camera jam its time code
properly. In the case of a Red camera this would normally be set this to 1000MS.

Audio Output Connectors
There are two TA-5M connectors on the back panel. How they are used varies based on the output configuration
in the extended menu.
Single Analog Channel out of one TA5
Two Analog Channels out of one TA5
AES Digital out of TA5
The TA-5 connectors can also be used to output AES digital audio. Each TA5 will output a stereo pair on pins
1, 2 and 3 with pin 1 being ground.
When receiving audio from a mono transmitter the QRX will output the same audio on both pairs of the
TA5. When receiving audio from a stereo transmitter the QRX can output both signals on a single TA5.
IMPORTANT: While sending digital audio, it is necessary that the unit on the other end (recorder, mixer, etc.)
have digital inputs with sample rate convertors, as there is no way to synchronize the output data with the
recorder’s digital input.
