The top example is what you should normally see. The bottom example is what you see if you have selected the
ALL choice for Unit Code. Since it’s a really BAD idea to command all transmitters to start using the same
frequency, this warning basically reminds you to choose a specific transmitter.
While you are changing the frequency on the display, the command is not sent to the selected TRX9xx transmitter
until you stop on a specific frequency for longer then 1.5 sec. This prevents the TRX9xx unit from transmitting on
all channels between the old and new frequencies. The transmit counter, bottom line right three digits, will
increment and an asterisk (*) will blink, for each message sent (several will be sent each time you press the
INC
or
DEC
button). If you are at the extreme edge of your range, you may need to take additional actions to get the
change to take place (i.e. re-orient your antenna, have talent move closer, etc.).
Remote Power Setting Change page
REMOTE POWERMODE
0: POWER=ON
Page purpose:
This page modifies the power setting to be used by each remote transmitter.
Parameters:
6: POWER=LOW2
– Disables the RF Power Amplifier, RF Board and Mic Pre-amp. In most cases, you want
to use
Low2
if you are using the remote power setting. When using the
Low2
setting, the TRX900 ( /AA) draws half the current as the full power setting, saving
battery life.
5: POWER=LOW1
– Disables the RF Power Amplifier in remote units.
4: POWER=ON
– Filler to prevent accidentally turning Off the remote unit’s power.
3: POWER=ON
– Filler to prevent accidentally turning Off the remote unit’s power.
2: POWER=ON
– Filler to prevent accidentally turning Off the remote unit’s power.
1: POWER=ON
– Filler to prevent accidentally turning Off the remote unit’s power.
0: POWER=ON
– Turns the remote unit’s power fully ‘ON’.
NOTE:
If the TRX9xx is not in range of the IFB or is on the fringe of coverage, the power setting command may
have to be repeated.

The IFB100’s timecode generator is in Free-Run mode unless it is connected to a timecode source.
If an external timecode source is connected, the IFB100’s internal timecode generator stays in sync with it. If a
TRX9xx/ZFR100 is in Autoload mode, starting and stopping recording is controlled by the external source.
IFB Frequency page
IFB FREQ 2.403
Page purpose:
This page sets the IFB transmitter’s center frequency.
Parameters:
[value range:
2.403
to
2.475
GHz, step:

The IFB100 should be adjusted with a
minimum
2 MHz separation between channels. However, 8 MHz
separation between channels is necessary when using the Zaxcom Voting System (ZVS).
If the ZVS is enabled, you need to allocate four adjacent channels, 2 MHz apart, for the IFB100s. For example, the
ZVS would use 2.403 GHz, 2.405 GHz, 2.407 GHz and 2.409 GHz. This makes 2.411 GHz the next channel
available for another ZVS group.
Using 2 MHz spacing, the IFB100 can simultaneously support 36 IFB channels.
