Section
1 System Overview
This section provides an overview of the MRC CodeRunner 4 Central Receiver. For a
system block diagram of the receiver, see
The CodeRunner 4 Central Receiver is capable of receiving in both analog or digital mode.
In the analog mode, the receiver outputs an NTSC signal with 4 audio channels, baseband,
and filtered video. In digital mode, the receiver outputs a digital data stream using either an
internal or external modem.
The incoming RF signal is down-converted to 70 MHz, filtered, and amplified. The output
from the IF Amplifier is split into two paths:
•A +5 dBm signal is routed to an analog demodulator, if one is installed.
•A second –10 dBm signal is routed to the power distribution board on the RF shelf.
Here the IF is switched to a direct rear panel connection. The switch is controlled
from the front panel display and keypad.
Power is brought to the receiver via a rear panel receptacle mounted on the plug-in power
supply. The power is routed through the rear panel backplane to the front panel display and
to the power distribution board on the RF tray,
All receiver functions are controlled from the front panel display and keypad. The receiver
can be controlled remotely and switched between analog or digital mode from either the
local or remote location.
The front panel displays common system faults with four LED indicators for power,
squelch, summary alarm, and remote/local status. Summary alarm messages appear as
scrolling text on the front panel LCD, A list of summary alarms and troubleshooting guide
can be found in

2.1Unpacking and Handling
Each unit is shipped assembled, wired, and factory tested. Each unit is packaged in
appropriate shipping containers. Care should be taken when removing equipment from the
container to prevent damage to the unit. Check that all parts and accessories are removed
from the container and packing material before they are discarded. Verify that the
equipment items shipped agree with those listed on the sales order.
Note:DO NOT discard the container or any packing material until the
mechanical inspection has been satisfactorily completed. This
material must be available in the event that a damage claim needs to
be filed with the shipping carrier.

Section
5 Remote Operation
The receiver can be set to operate in local or remote mode using the front panel keypad and
LCD display. For the receiver to operate from a remote location, a connection must be made
between the receiver and the master antenna controller or control device. This section
describes how to assemble the control cable and interpret the various control states.
5.1Local and Remote Operation
The receiver is set to local or remote mode using the front panel keypad and LCD. See
Section 3, Operating Controls on page 3-1.
When the receiver is set to local mode, the following conditions occur:
•All receiver functions are controlled using the front panel keypad, and remote
device commands have no effect.
•If a remote device is connected to the receiver, front panel controls override any
commands from the remote device. However, the remote device status outputs
remain functional.
When the receiver is set to remote mode, the following conditions occur:
•All receiver functions are controlled by the remote device using the interface cable.
•Commands from the remote device control all functions of the receiver and override
the front panel controls. If the remote device line connection should become open,
the receiver remains under local mode even though the device is set to remote.
•The remote setting does not force the REMOTE mode, but rather allows the remote
device to determine whether the receiver will be in the local or remote mode.
•If no remote device is connected to the receiver, the receiver will remain in local
mode, even if the front panel controls are to set to remote.

Remote Operation
Command Inputs to the Remote Connector
5.2Command Inputs to the Remote Connector
The remote device connects to the rear of the receiver using the remote interface connector
(J7) as shown in
J7 is shown in Table 5-1.
Pin functions are grouped into two categories: Control functions and Status Outputs.
Commands are sent by the remote device using the following logic states:
•The logic 1 is +5 V nominal (3.5 to 5.5 V).
•The logic 0 is 0 V nominal (-0.5 to +0.8 V) or open. Inputs have 10 K ohm pulldown resistors to ground. +5 Vdc is available at the remote interface.
A logic level of “1” is equal to +5 V, which is supplied on Pin 10 of the Remote Interface
Cable.
For remote commands to be functional, the following conditions must occur:
•The front panel control must be set to the remote mode.
•The remote mode command at J7 pin 8 must be set to 1.
•All commands must be sustained for the duration of the desired mode.

Command Inputs to the Remote Connector
A +5 Vdc (+/- 0.25 V) is made available on J7 pin 10 for loop-back as a command function
and for operating low power circuitry in the remote interface equipment. This output is
current limited and should not exceed 4 mA of load.
5.2.2.1Ground
Signal (and chassis) ground is made available on J7 pin 1 for loop-back as a command
function and as the return for the +5 V bias supply.
5.2.3Status Outputs – Remote Connector J7
Status outputs are functional in both LOCAL and REMOTE modes.
5.2.3.1Receiver Signal Strength Indication - Analog
A buffered S meter output is made available on J7 pin 13.
•No signal strength (no RF input) = 0 V.
•Maximum signal strength (-35 dBm RF input) = +1V. Output impedance is 1 K
ohm.
5.2.3.2Remote Mode Status
Active Low - J7 Pin 9
•Ground = Receiver is in the REMOTE control mode
•Open circuit = Receiver is in the LOCAL control mode.
•Open circuit = Receiver is operating correctly with an adequate received signal.
•Contact closure = Receiver has squelched video output due to inadequate received
signal.
A contact closure (i.e., alarm) also occurs when the Receiver is turned OFF.

6 Media Switch
6.1Overview
The optional Media Switch lets operators switch between analog and digital modes where
both applications are used. The switch provides for separate video and audio or for
baseband composite.
The Front Panel Keypad and Display controls the operating mode as shown in Figure 3-10,
Video Demodulator Screen on page 3-9. The same “IF CNTRL” signal used to change
modes in the receiver is routed to the media switch using an optional cable allowing
simultaneous switching between both the analog and digital sources.
Figure 6-1shows a block diagram of the CR4 Receiver and Media Switch when used with
the Alteia Receiver for switching both video and audio.
