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 either 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.
