9/15/2008 Incident Commanders’ Radio Interface ™ A Rapidly Deployable, Radio Interoperability Solution for Public Safety Personnel MANUFACTURED BY COMMUNICATIONS-APPLIED TECHNOLOGY CO., INC. RESTON, VA., USA CAGE CODE: 0EEY2 http://www.c-at.com If you have any questions, please contact: C-AT TECHNICAL SUPPORT at 800-229-3925 x23 (voice) 703-471-4428 (fax), or E-mail to techsupport@c-at.com...
Theory of Operation The “2P” can provide a communications bridge, or link, between two public safety agencies with otherwise incompatible radios; can quickly establish the link as a tactical situation rapidly unfolds; and requires minimal resources to enable it initially, or to maintain its operation over many hours. The 2P will remain fully operational for 30+ hours powered by an external “AA”...
Pre-Operational Activities Some pre-planning is necessary to ready the ICRI for rapid deployment. The following should be accounted for before placing the ICRI on-line: 1. Determine what the power source will be for the ICRI. Verify that the internal battery is charged or that one of the external power source option are available 2.

Interoperability DOs and DON’Ts These simple “universal” rules will help to ensure that the part of communications interoperability will work properly. 1. Verify that only one interoperability bridge in the area is using the radio frequencies that you will be using. 2.
INITIAL SETUP As a minimum, the following will be required for ICRI operation: ICRI assembly Charged internal Li Ion battery or power supply with interconnect cable to ICRI Two radio interface cables or a radio interface cable and a cell phone cable (no external cable needed for land-line phone connection) ...
Pelican Case ICRI Storage This ICRI is provided with a Pelican™ transit case with custom foam cutouts for storage of the ICRI and cables. A status board for quick identification of connected radios/agencies is mounted within the case, behind the cover foam. Opening the Pelican case may require relieving the partial vacuum that forms when the case has been relocated from one altitude to another (more than 1000’).

FIGURE 4: INTER-AGENCY COMMUNICATIONS STATUS BOARD "WHITE BOARD" The Inter-Agency Communications Status board is located behind the foam on the top of the Pelican™ case. This board is to be used only with dry erase markers to indicate which agencies are connected to the ICRI and each other during an incident.
Controls and Indicators Front Panel FIGURE 5: FRONT PANEL RADIO INTERFACE JACKS (1 and 2) ° The 2 radio interface jacks on this unit are a 5-pin 180 locking-DIN type jack. Make sure the interface cable is fully seated before use. The radio’s internal speaker and hand mic functions are disabled. Use the ICRI handset to talk/listen if using the ICRI as a base station (a remote speaker jack is an ICRI option).

To use the internal power source, place the handle of the switch in the UP position (labeled “internal battery”). To use an external power source place the handle of the switch in the DOWN position (labeled “EXTERNAL BAT/CHG”). If the external power source is at least 10.5V, the internal battery will charge while the ICRI is operating AND the power switch is in the EXTERNAL BAT/CHG position The ICRI is not operating when the switch is in the middle/centerr position is OFF.
Rear Panel FIGURE 6: REAR PANEL DC INPUT JACK: This is a 2-pin locking-type jack is the input. Reverse polarity protected. Pinout: 1 - +10.5 to +20 VDC 2 - Ground ICRI Link (RJ45) Jacks: This “RJ45” jack allows the ICRI to be linked to another ICRI using C-AT cable #179.0692. When linked all connected devices are able to “talk”...
ICRI Power Select the power source to be used Internal Li Ion battery C-AT 12 volt battery pack (uses batteries) 12 volt vehicle battery Vehicle cigarette lighter 115V AC (with an external adapter) BA590 “military” battery ...
Power the ICRI with the optional C-AT battery pack (8 “AA” cells) The battery housing is comprised of two parts; the exterior case and an internal tray. NO TOOLS ARE NEEDED TO REMOVE THE TRAY AND REPLACE THE BATTERIES. FIGURE 8: BATTERY INSTALLATION (DRAWING) Hold the battery housing securely in the palm of the hand with metal battery terminal plate facing up.
Power the ICRI-2P with cigarette lighter or alligator clips cable (P/N 179.0730) NOTE: The cable assembly consists of three subassemblies: (a) the universal interconnect cable, (b) the cigarette lighter plug with locking in-line jack and (c) the alligator clips with locking in- line jack.
Portable Radio Interface NOTE: Radio interconnect cables are generally specific to a radio brand and model, although some manufacturer’s use the same connector for several radio models. Interconnect cables provided by C-AT have a seven digit part number label on the cable. A chart, crossing these numbers with the radio brands/models appear in Appendix A of this manual.

FIGURE 15: RADIO WITH ICRI CABLE ATTATCHED FIGURE 16: JACK ASSEMBLY (DRAWING) To disconnect the connector for cable storage, push inward on the locking ring with minimal force, and at the same time turn the ring counter-clockwise 1/8 (45 ) turn to release the locking mechanism. Then, holding the metal barrel of the connector, pull the connector straight out of the jack.
Operating the portable radio after cable connection After a radio is connected to the ICRI, the radio’s internal speaker and microphone is disabled. The user will be unable to hear any audio or speak from the connected radio. To verify the radio is transmitting and receiving properly, use the local handset (See Section 6. Using the Local Handset) Using a Nextel phone in Direct Connect...
Setting radios to “bridge” through the ICRI-2P Set the volume control on each connected radios to mid position between fully CLOCKWISE and fully COUNTER-CLOCKWISE. Set each radio to the desired channel. NOTE: The radios must not be on the same channel/frequency. NOTE: If the radios are in the same band (eg: VHF or UHF or 800MHz) considerable separation of the radios will be necessary to minimize “desensing”...
Land-line Telephone, Cellular Phone Interface The ICRI-2P is equipped with an RJ-22 modular jack; the jack is located on the rear of the ICRI. Though this jack a standard telephone handset station/keyset, a cellular telephone, or military STU/STE telephone can be connect to ICRI to quickly establish a “patch” with radios also connect to the ICRI.
Connecting a cellular telephone to the ICRI-2P When connecting to a cellular telephone using the interface cable, P/N 179.0693, insert the 2.5mm (1/16”) plug into the headset jack on the cellular telephone. Be sure it is fully pushed into the telephone’s jack;...
The Local Handset The handset provides the user with a local interface to the ICRI, without using a radio. It will allow an individual to hear and respond to all audio transmitted through the ICRI from the radios and telephone connected to the ICRI. Using the handset Connect the handset to the jack labeled “Handset.”...
ICRI TO ICRI LINK Connect the supplied “cross-over” RJ-45 cable, p/n 179.0692, between the two units. Cable drawing is located in the Appendix. Operate the ICRIs as normal. It is not necessary to power off or restart the ICRIs after connecting/disconnecting the link cable.
ICRI Unit Identifier The ICRI has a “Bridge ID” announcement that is transmitted every 10 minutes unless disabled . Each ICRI has a unique ID (for example, “FAM Gateway Eleven”). This message will not be broadcast if the ICRI is receiving input (voice) from any of the devices connected to the ICRI--- the message will not interrupt any audio activity, but will wait for activity to cease before broadcasting.

FIGURE 28: ICRI BOARD ADJUSTMENTS NOTES FOR ICRI-2P CONFIGURATION DRAWING: INPUT BLOCKING TIME JUMPERS: With jumpers "on", the ICRI will respond to a new voice signal approximately 0.25 seconds after the last transmission has ended. This is the standard configuration. With the jumper removed, this time is extended to approximately 2 seconds.
Appendix E: Some Interoperability DOs and DON’Ts These simple “universal” rules will help to ensure that the part of communications interoperability will work properly. 6. Verify that only one interoperability bridge in the area is using the radio frequencies that you will be using.
APPENDIX F: FCC Part 15.21 Information to User: Caution! Change or modification not expressly approved by the party Communications-Applied Technology could void the user’s authority to operate the equipment. 15.105(b) Information to User: NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
