Instructions for rear
cabling of the
transmitter
1. Connecting audio basic X5 with 8-pin patch cable, especially audio TX
lines and PTT contact. The PTT contact can be adjusted to the
system's physical characteristics and configured as necessary via
service PC setup. With factory setting the PTT input shall be switched
to ground at PIN X5.9.
2. Ethernet – LAN: Connecting Ethernet LAN remote control X6 via
LAN to the remote control computer.
RS-485: Connecting RS-485 remote control X7 to the remote control
computer.
3. Establish a connection to ground, e.g. via the 19" rack. Ensure that the
grounding line has the required cross-section (observe VDE
regulations).
4. Connecting transmit antenna to N-connector X3.
5. Connecting main AC supply 115/230 V to X1.
The power supply unit completely covers the voltage range 115 V and
230 V without separate switchover. You do not need to manually select
and preset the voltage.
6. Connecting DC battery supply 28 V to X2.
The radio can operate from either an AC or DC supply. If both voltages
are connected, the radio will automatically switch to the DC battery
input if the AC supply fails.
Note: The RS-485 interface is only available if the external motor tuned
Telsa filter is not configured (see chapter
3.7).
Note: See chapter
6.2 for additional information on interface description.
