2.4.2 DATA Connections

The connection for the Ethernet interface that carries the signals in and out of the radio is a RJ45

10BaseT connection.

2.4.3 Auxiliary Data Connections

There are 5 auxiliary data connections for Tsunami as shown in Figure 2-3.

This connector is used to link two Tsunami radios at a repeater site for Orderwire

operation. This would allow orderwire "telephone" calls to and from any point in the

Tsunami network.

The Tsunami orderwire circuit can also be connected to other existing

orderwire networks. See Section 3.14.1 for details.

ALARM

This connector is used for monitoring alarms electrically. The alarm connections are

essentially the same as described for the front panel, however instead of LED

operation, alarm status is provided electrically by means of TTL and Form C relay

connections. The TTL and Form C relays can be connected to other transmission

equipment for monitoring alarm status locally or remotely.

DIAG-

NOSTICS

This is a serial interface port (RS-232 or RS-422, ≤9600 baud) to the Tsunami radio.

This port provides maintenance information about the Tsunami radio(s) to a

connected computer or terminal. This port is typically used for maintenance and

troubleshooting.

AUX

DATA

This is a serial interface port (RS-232 or RS-422, ≤9600 baud) which allows the user

to connect auxiliary serial data from one point in the radio network to another. This

facility can also be used for bridging the DIAGNOSTICS port for remote alarm and

status monitoring or for connecting other equipment's serial alarm information. It can

alternatively be used for separate data connection for serial devices.
