2.6 Equipment Configuration Samples

RCU6512 with RT6512

RT6512 transceiver operated by RCU6512 controller using the RS422 interface.

Figure 8: RCU6512 with RT6512

Dual controller configuration for tandem operations is not available

with RCU6512.

2.7 Aircraft Wiring

The installation of the device(s) depends on the type of aircraft and its equipment

and therefore only general information can be given in this section.

Installation Switch (INS_SW)

It is necessary to install a switch to get access to the RT6512 installation parameters.

•

Access to RT6512 installation parameters is only possible when RT6512 /SERV_EN line

is connected to ground.

o

RT6512, connector P1/28 → turnkey (INS_SW) → GND.

•

Setting of RT6512 installation parameters are available only when installation

switch* (INS_SW) is closed.

•

Otherwise settings of RCU6512 installation parameters only will be possible.

* For details see "Figure 9: RT6512 with RCU6512 as Primary Controller", page 32).
