The EX7100 is compatible with the industry standard 19" rack system and occupies 3U

 

(VHF) or 4U (UHF) of vertical space. 

> 

Attach the handles to the EX7100 front panel using the handle kit supplied. 

> 

Attach the front panel to the radio terminal using the six screws supplied. 

> 

Mount the terminal to the rack using the four front panel mounting points. Due to the 
weight of the EX7100 terminal (approx. 15 kg), it is highly recommended that the 
terminal be supported with the use of angled side rails. These rails are commonly 
found in 19” racking systems (but are not included with EX7100 terminals). 

>  Ensure that the terminal’s chassis ground is connected to the equipment rack’s 

ground via the chassis earth screw terminal. (Refer to Section 2.8) 

Cable configuration is dependent on the variant of the terminal being installed, i.e. Data, 
Exchange, or Subscriber. (Refer to section 1.2) 

However, there are some generic connections required, regardless of variant type: 

> 

The RF connection, 

> 

The power supply connection, 

> 

The earth connection. 

VHF system: The VHF EX7100 uses an internal duplexer Connect the antenna’s coaxial 
cable to the N-type socket marked ‘ANT’. 

UHF system: The UHF EX7100 uses an externally mounted duplexer. Connect the 
antenna’s coaxial cable to the N-type antenna socket on the lid of the terminal. If the 
duplexer leads have been disconnected from RF connectors on the rear panel, it is 
important they are reconnected correctly. 

 

The connector marked thus:               is connected to the Transmitter. (RF out). 

 

The connector marked thus:               is connected to the Receiver. (RF in).
