10/100baseT data interface
Connection is though the Ethernet RJ45
connector on the electronics compartment.
Interface is IP4 with fixed address which can
be configured.
The Ethernet interface is not activated by software
versions covered in this instruction manual.

Serial connector – DB25
The 25-pin serial connector on the
electronics compartment is female. The
radio cable should have a male connector to
match. Table 8 lists the interface signals
available on each pin of the connector.
3 Vdc or 9 Vdc configurable signals
Voltage range 3 Vdc or 9 Vdc configurable,
only one voltage, called the signal supply is
configured for all these signals.
These signals supply an alternative data
interface to RS232 to operate with radio/
modems which have logic level types of
serial interface.
The signal supply itself is also available on
pin 22.
Maximum output current for all lines is
10 mA.
