2.3 Physical Description

The following sections describe the physical features of EVENT 5800 digital radios.

2.3.1 Back Panel

The following illustration shows the general format of a EVENT 5800 back panel.

Figure 2-3. Transceiver Back Panel

This illustration shows the back panel of a transceiver unit that can be configured as a

transmitter or receiver. The following illustration shows the back panel of a receiver-only

unit.

Figure 2-4. Receiver-Only Back Panel

Note that the back panel of a EVENT 5800 unit will be slightly different depending on the

number and type of hardware modules installed. Some modules are standard and

included in all units. Optional modules may be ordered and installed to support specific

functional requirements.

2.3.2 Hardware Modules

The lower section of the EVENT 5800 chassis is comprised of hardware modules. The

number and type of modules depends on the type and required functionality. A maximum

of eight of modules can be installed in the chassis. A minimum of five modules are

required in a basic EVENT 5800 configured for 1+0 operation. They are:

 Power Supply Module

 Controller Module

 Modem & I/F Telemetry Module

 Master I/O Module

 Mini I/O Module
