RF Connector Sealing 

Ensure  that  the  RF  connections  to  the  TTA  are  appropriately  sealed  with  self 
amalgamating tape to prevent ingress of moisture. 

RMC FRONT PANEL 

Ethernet Interface (LAN) 

Connect to the front panel Ethernet port (LAN) using the supplied cable either locally 
using a PC or remotely via a TCP/IP network. To begin a session, start your web 
browser and type the factory default IP address - http://192.168.1.200 - into the 
address field. A successful connection is indicated by the display of the log in 
screen. Log in as a level 2 user with the default User Name, “admin” and Password, 
“admin”. The Ethernet interface is fully compatible with both standard and crossover 
Ethernet cables. 

If the IP address has been changed from the factory default setting and is not 
known, the unit will need to be reset to factory default settings using the rear panel 
reset button. If the web browser is unable to open a session it may be necessary to 
set the IP address of your computer to an address in the same range as the RMC, 
e.g. 192.168.1.180 

POWER LED 

The green LED is on when external power is present. If the LED is off then either the 
DC voltage supply is disconnected or the wrong value, or the polarity is incorrect. 

RMC FAULT LED 

The red LED will light under the following circumstances. 

• 

The internal power rails are outside the normal operating range. 

• 

The internal amplifier currents are outside the normal operating range. 

• 

The  voltage  and/or  current  feed  to  the  TTA  is  outside  the normal  operating 
range. 

• 

The RMC internal temperature is outside the normal operating range. 

GAIN LEDs 

The  yellow  LEDs  indicate  which  gain  mode  is  active.  If  the  yellow  switch  LED  is 
blinking  then  a  value  outside  the  available  values  has  been  set  on  the  rear  panel 
Gain Attenuation or Configuration switches. 

LAN Gain Mode 

Using the Ethernet interface the system gains can be set-up and monitored 
either locally with a PC or remotely

 

via a TCP/IP network. 

SWITCH Gain Mode 

Four  rear  panel  rotary  switches  are  provided  for  local  set-up  of  the  receive 
system  configuration  and  gain.  They  should  be  adjusted  as  described  in 

SYSTEM SET-UP

Resetting the RMC to Switch Gain Mode 

If  the  RMC  is  in  LAN  Gain  mode  but  the  user  does  not  have  access  to  a 
computer, the unit can be forced into Switch Gain mode by setting the two 
rotary  Input  Gain  Attenuator  switches  to  “99”  and  cycling  the  power.  This 
does not affect any other settings.
