TN652 CI-RC-4M-G2 Multiple Link Controller
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.
