The CI-RC-4M-G2 Multiple Link Controller provides control capability for up to four receiver / transmitter pairs in an
MT-4E repeater radio system. The CI-RC-4M-G2 controller provides the following features:
• interconnection (LVDS Serial Data routing, COR-PTT routing, Audio routing) of up to four receiver and four
transmitter modules in any confi guration (repeater, repeater with links, crossband systems, etc.).
• four-way analog audio bridge allowing analog to digital and digital to analog conversions with up to four pairs of
radios (with adjustable audio levels).
• multiple CTCSS tones and NAC codes may be selected to operate each connection between receivers and
transmitters (up to seven CTCSS/NAC for each link).
• DTMF control of receiver to transmitter links.
• setting of receiver priorities.
• transmitter channel switching based on received CTCSS or NAC.
• auxiliary E&M connection.
• acknowledge tones for each transmitter on DTMF disable / enable.
• custom jumperable Repeat Disable line for controlling analog bridging (links) and E&M connections.
• current draw of 8 mA to 72 mA dependant on system confi guration (17 mA to 27 mA without audio bridging).
• 2 independent general purpose outputs that can be controlled by NAC, CTCSS or DTMF
(open collector 750 mA / 30 Vdc max).
The MT-4E receiver and transmitter modules all plug into the CI-RC-4M-G2 repeater controller via cables that plug
into the RJ45 jacks on the front panel of all the modules. The CI-RC-4M-G2 comes with eight diff erent cable lengths
to plug into the eight receiver and transmitter modules. If the system only uses some of the cables, the other cables
can be kept for future system expansion or as spare cables. The CI-RC-4M-G2 is 19” rack mountable in 1 RU of
rack space.

Installation:
In addition to the RJ45 interconnect cables on the front panel, the +9.5 Vdc power and ground must be connected
on the back panel. Figure 1 shows a diagram of the back panel of the CI-RC-4M-G2.
Figure 1:CI-RC-4M-G2 Back Panel
A female DB25 connector on the back of the subrack (J12) can be used for connectioning to the CI-RC-4M-G2
using a standard straight-through male-to-male DB25 cable. The A-PNL-AUX96-3 auxiliary connector can also be
used to connect to the CI-RC-4M-G2, as shown in Figure 2. The information in brackets is the function that uses
that particular connection. For example, if you are using CTCSS tones, the Rx Disc O/P must be connected. The
diagram only shows connections for Receiver and Transmitter A.

Multiple Link Controller Programming:
The CI-RC-4M-G2 multiple link controller is software programmable using the MLCS (Multiple Link Controller
Software). The MLCS allows fl exible programming options for the radio system. A type A to 5 pin mini-type B USB
cable is used to connect the USB port of the computer to the USB port on the front panel of the controller. The
System Settings and Receiver / Transmitter Links windows are shown in Figure 3.
Figure 3: Sysytem Settings and Receiver / Transmitter Links
The Receiver / Transmitter Links window allows for a wide variety of complex repeater confi gurations using a link
confi guration grid. The grid uses color coding to indicate diff erent connection settings.

Each link on the grid can be programmed separately for a diff erent confi guration. Three diff erent link confi gurations
are shown in Figure 4: COR Controlled Link, DTMF Controlled Link and a Conditional Link (with both CTCSS and
NAC conditions, as well as Channel Selection capability).
Figure 4: Link Configurations
Figure 5 shows the CTCSS selection window (CTCSS tones need to selected globally for the CI-RC-4M-G2),
Channel Selection window and General Purpose Output window.

Analog Audio Bridging Circuit:
The CI-RC-4M-G2 controller is equipped with a 4 way analog audio bridge. This audio bridge allows the user to
interconnect RF modules using an analog audio interface similar to the AC-3E and BC-4E products. It allows the
user to interconnect up to four RF modules modules as well as an auxiliary audio input and output.
On the multi-link controller there is an audio adjustment pot for each audio path available. The block diagram on the
next page (see Figure 6) shows the audio routing and audio pot adjustments.
To enable a specifi c audio path, the appropriate audio jumper must be removed. For the specifi c audio jumper
required for enabling the appropriate audio path, refer to the jumper table below:
JU53 RXA to TXA Audio Disable JU63 RXC to TXA Audio Disable

The IP-223 keys up the UHF Base Station
Transmitter in Digital Mode.
The UHF Transmitter can transmit
three different NACs to the UHF Receiver
at the High Site.
The UHF Receiver (RXB) Receives
one of three separate NACs
and changes the channel of the
VHF Transmitter (TXA) to Air Guard,
Flight Following or Air Detect.
P25 DIGITAL LINK
Three VHF Receivers receive
on Flight Following (RXA),
Air Guard (RXC),
or Air Detect (RXD)
and Transmit the Received signal
on the UHF Transmitter (TXB).
ANALOG LINK
The UHF Transmitter (TXB) Transmits
the received VHF signals back to the
UHF Base Station Receiver.
The Air Guard Receiver (RXC)
has High Priority.
The Multiple Link Controller can be programmed to change channels based on CTCSS (for an analog link) or NAC (for a digital link).
The UHF Receiver (RXB) needs to connected via
LVDS serial data for the NAC detect and
also through the audio routing circuitry in
order to allow the P25 Digital to Analog conversion.
The UHF Receiver (RXB) de-vocodes the P25 Digital
signal and outputs audio that is routed to the
audio input of the VHF Transmitter (TXA).
VHF TXA Ch. 1 = 168.650 MHz / CTCSS 110.9 Hz = Flight Following VHF TXA Ch. 2 = 168.625 MHz / CTCSS 110.9 Hz = Air Guard VHF TXA Ch. 3 = 168.750 MHz / CTCSS TBD = Air Detect

Multiple Link Controller Conditional Linking and Channel Change Programming:
The Multiple Link Controller can be confi gured to operate as a Conditional Link. If the Conditional Link is selected
the path from Rx to Tx will only be active if the received signal contains one of the programmed CTCSS tones or
NACs. Up to 7 CTCSS tones or NACs may be programmed into a Conditional Link.
The Multiple Link Controller can also be programmed to allow for Channel Selection of the transmitter, based on
the received CTCSS tone or NAC. To activate the Channel Selection for a link, the link needs to be programmed
as follows:
• Open the Rx / Tx Link confi guration window for the link required.
• Select the Conditional Link check box.
• Select the Enable Channel Selection check box.
• CTCSS tones / NACs are not required to be programmed into the Rx / Tx Link confi guration window. Programming
CTCSS tones / NACs in the Rx/ TX Link confi guration window limits Channel Selection to ONLY these 1 to 7 codes.
Leaving these selections as “none” will pass ALL CTCSS tones / NACs to the Channel Selection tab.
• A grey dot with the C (for Channel Selection enabled) will show on the grid (the dot will be blue if CTCSS tones /
NACs were programmed into the Conditional Link).
• The CTCSS tones / NACs used to change the channels should be programmed in the Channel Selection tab.
Note that the Multiple Link Controller will ONLY allow up to 15 Channels changed based on CTCSS tones, as it
can only allow up to 15 CTCSS tones programmed globally for the entire controller. An unlimited number of NACs
can be used for Channel Selection as the NACs are not required to be programmed globally
