The Installation of the device(s) depends on the type of aircraft and its equipment.
REU6100-X-(3XX).
Address Coding
• Set the address coding for the devices (REU6100 but not for variant REU6100-X-(3XX) by
connecting the pins L, M, A, B (ground or left open).
• This function is not used for REU6100 but necessary for ACU installation.
Therfore the ACU address coding is shown here in addition:
• Set the address coding for the devices (ACU) in the cable-plug connector to the ACU.
• Each ACU must have a different address:
2.7 Aircraft Wiring
Electrical Bonding and Grounding
The REU6100 has a threaded grounding bolt at the housing. Use this point as grounding contact.
It is therefore only possible to give general guidelines in this section.
• Use only cable fit for aviation (self-extinguishing).
• AW G 20 for power supply and AWG 24 for other cables.
• The interface lines are each to be laid as 2-core twisted and shielded
(AWG 24) cables.
• Each single cable harness of a device connector must have separate
shielding.
• Rubber sleeves are to be fitted over the soldering points on the device
connector.
• A fuse or circuit breaker should be fitted in the power supply of the
REU6100 (see "Technical Data" page 23).
• RF cable should not be included in the cable harnesses.
• Examine the wiring carefully before turn on the devices, make sure that
(UB+) and (GND) are not mixed up.
• The one-to-one replace of a device REU6100-X-(3XX) with a device not
REU6100-X-(3XX) and vice versa is not possible.
• The pin assignment of connector P5 is different with the variant
• Make sure that the device is correctly connected to aircraft ground
(structure).
• Make sure that the resistance between the component which ensure
equipment bonding and any point of this item of equipment do not exceed
2.5 mΩ.

Double Transmit and Multi Transmit (Simulcast) Mode
The REU6100 can operate in double transmit or multi transmit (simulcast) mode.
• In double transmit mode the REU6100 can transmit on two predefined radios at the same
time.
• In multi transmit mode the operator can select on which radios he wants to transmit at the
same time from his ACU610X.
• The radios for transmit operation at the same time are predefined by the configuration
setup.
• The operator can still listen to radios which are not configured for multi transmit operation.
Guard Radio PTT Function
The REU6100 has a guard radio PTT function for 2 guard radios.
• The transmission of the guard radio is started by guard radio PTT (discrete inputs alert
tone 1 and Selective Call input).
• Two guard radio PTTs can be configured to TX-channel 1...8 and to 2 of 6 ACU610X or
headset operators.
• Only one guard radio PTT (discrete input) can be configured to one ACU610X - or one
headset operator.
• If a guard radio PTT (discrete input) is started, the related radio status LED blinks.
• The guard radio PTT has a higher priority than any other PTT for this radio.
o If two operators are configured for the same guard radio, the priority is given to the
user who starts his guard radio PTT first.

The REU6100 can operate in relay mode alternative to dual TX- and multi TX-mode.
• Only one user can be selected as a relay operator.
• In the relay mode the number of independent operators and related control devices (ACU)
decreases around 2. For example, for:
REU6100-2-(XXX) from max.4 to max. 2 independent operators.
• REU6100-3-(XXX) from max.6 to max. 4 independent operators.
• The selection of two transceivers out of the eight available TX-channels is possible
o The selection can be done by activation the monitoring (knob release) of the
r
elevant TX-radios.
o The selection of the TX-channels for relay operation can be configured in th
onfiguration setup.
c
• For relay mode operation the transceiver must have a discrete output
(low active) for call identification.
• The headset in/output of number HS5 and HS6 must be connected for
internal use.
• The alert tones 1...8 are not available if relay mode is configured.
