3 Requirements & Capabilities Equipment is patented by Communications - Applied Technology (C-AT) and there are various configurations ranging from 2 radios w/1 talkgroup to 10 radios w/4 talkgroups we will concentrate on the 5 radio, 2 talkgroups option5 radio I/O, 1 telephone I/O, handset/headset I/O, 2 talkgroupsSmall (10” x 3” x 7”), rugged package/ circuitryPortable (3.5 lbs)Rapidly deployable (typically under 5 min.)Minimal “operator” training requiredAlternate power sources: V AC 50/60 Hertz, vehicle-supplied 12 volts DC, 8 AA Batteries
4 Requirements & Capabilities Power Options AC AdaptorCar battery8 AA
5 Requirements & Capabilities Physical Layout A – DC Input JackB – ON/OFF SwitchC – OK/ Low Voltage LEDD – OK/ Low Voltage LEDE – Radio Interface Jacks (1 thru 5)F – Telephone Interface JackG – Handset Interface JackH – Handset Volume ControlI – Voice Activated Circuit (VOX) LED IndicatorsJ – Talk Group Switches
6 Setup & Configuration ICRI with Attachments (Not to scale) 1. Ports are not radio specific (mobiles or portables)2. User instructions on top cover3. Interconnect cable technical notes on bottom cover
7 Setup & Configuration Prior to Activation Some pre-planning is necessary to ready the ICRI for use. The following should be accounted for before placing the ICRI on-line:Predetermine what the power source will be for the ICRI and verify that the cable or battery pack is availablePredetermine what brand and model of radios will be connected to the ICRI and that an “interconnect” cable for each radio is available12 or 24 volt vehicle batteryVehicle cigarette lighter115VAC (with an external adapter)BA590 “military”Commercial dry-cell battery (12V or greater)C-AT 12 volt battery pack (uses 8 “AA” batteries)
8 Setup & Configuration Prior to Activation (Continued) Advise agencies that they will need to supply a “spare” radio, for the radio interoperability, that the radio supplied must be known to operate properly and have at least one spare fully charged batterySeparate the interface radiosEnsure a clear field of viewOnly connect agencies that need to interoperateCoordinate gateway usageMemorandums of Agreement (daily operations)Communications Leader (COML) (per incident)Interfacing non-standard radios, the radio’s owning organization should provide:Interface cablesSpare batteries and/or chargersRadio configuration/channel list
9 Setup & Configuration ICRI Operation After connecting a power source to the ICRI, turn it on so that power up and input voltage can be verifiedWhen using a DC source voltage between 6.5 and 7.4 volts neither the OK nor the LOW voltage LEDs will light, but the ICRI will be functionConnect the radio interface cables to the ICRI (All five ICRI radio interface connections are electrically identical)Connect the radio interface cables to the radiosBe sure the radios are on the channels assigned to the interoperability functionTurn on the radio
10 Creating & Breaking Patches ICRI Select the talk-group the radio will be assigned to and place the switch above the associated port in the designated positionNOTE: The center position of the switch places any item connected with the associated port into a “NO CONNECTION” conduction without physically disconnecting the device from the ICRI.If used, connect the telephone and handsetNOTE: For initial setup and troubleshooting purposes, C-AT recommends the use of the local handset or headsetSelect the talk-group the telephone and/or handset will be associated with.Turn on the telephone.
