2 ICRI-2P Tactical Radio/Telephone Interoperability 2

3 Objectives Identify general information and description of the ICRI Describe the principles of operation of the ICRI Describe the maintenance procedures for the ICRI Understand how this equipment supports overall FAMS response 3

4 Theory/Principles of Operation 4

5 Theory of Operation The 2P performs two primary functions: Distributes the audio received from a two-way radio, or telephone, to a second radio also connected to the 2P. Utilizes this same incoming audio to key the other communications devices connected to the ICRI. 5

6 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 radios can be hand-held portables, vehicle or console radios, SPRINT/NEXTEL Direct Connect phones or a combination….conventional or trunked… land-line telephones, cell phones, STU, STE or satellite phones can also be connected to the ICRI. 6

7 The 2P will remain fully operational for 30+ hours powered by an external AA battery pack (8 AA alkaline batteries), 10+ hours powered by the internal, rechargeable battery, and indefinitely when powered by an AC source. The internal Lithium Ion battery will not provide a low battery warning (Green LED going off and Red LED coming on indicating 2-3 hours before battery charging/replacement is required). The AA battery pack will provide the transition. 7

14 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: a)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. b)Determine what brand and model of radios will be connected to the ICRI and that an interface cable for each radio is available. c)If radios are not maintained with the ICRI, advise participating agencies that they will need to supply a spare radio, for the radio interoperability. d)Verify that the radios are known to operate properly and have at least one fully charged battery or other reliable power source. The ICRIs internal regulated power supply is reverse polarity protected, but it is important to check polarity of DC supplies before connecting them to the ICRI. 14

15 INITIAL SETUP As a minimum, the following will be required for ICRI operation: a)ICRI assembly b)Charged internal Li Ion battery or external power supply with interconnect cable to ICRI c)Two radio interface cables and/or a radio interface cable and a cell phone cable (no external cable needed for land-line phone connection) d)Two radios and/or a phone 15

16 1)Determine power method and connect to ICRI, place the POWER switch in the ON position; the OK LED should be lit. If the Li Ion battery has been fully charged, it will provide at least 10 hours of continuous use. 2)Check the radios transmit and receive functions, battery and channel selection. Radios must not be in SCAN mode. 3)Connect one interface cable to the ICRI and one radio 4)Connect the handset. 5)Set the volume controls for the radios and handset to a position mid-way between fully CLOCKWISE and fully COUNTER-CLOCKWISE 16

17 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. POWERING THE ICRI WITH THE BATTERY PACK (8 AA cells): 17

18 TO OPEN THE BATTERY PACK: Hold the battery housing securely in the palm of the hand with metal battery terminal plate facing up. Push firmly on the center of the battery terminal plate, until the battery tray is released. Remove old batteries and discard properly. Replace the 8 "AA alkaline batteries, observing polarity markings within the tray. There is a key tab on the side of the tray and a keyway inside of case. To reinsert the tray, make sure the trays key goes in the matching slot side of the case. Insert the tray into the housing from the bottom end of the case, pushing the tray until it locks into place. 18

19 1. Hold the battery pack in the palm of your hand (Do not squeeze the sides too hard) 2. Push inward on the metal plate 3. The tray will slide out of the battery holder 4. Insert 8 AA batteries into the battery tray, then reinsert the tray into the holder

20 CONNECTING THE BATTERY PACK TO THE ADAPTER CABLE: To reinstall the assembled battery pack onto the adapter, align the slots on the top of the battery pack with the slide rails on the adapter. Slide the battery pack onto the adaptor until it locks in place and the edges of the battery pack are aligned with the edges. of the adaptor. 20

21 5. To reinstall the assembled battery pack onto the adapter, align the slots on the top of the battery pack with the slide rails on the adapter. Slide the battery pack onto the adaptor until it locks in place and the edges of the battery pack are aligned with the edges 6. Connect the plug, on either the battery adapter, to the jack on the ICRI (Align the arrows on the plug and jack) 7. Push the plug into the jack; it will lock 8.To remove the plug, hold the body of the plug (as pictured) to release the locking mechanism Do not turn the fluted end of the plug ….see step #6

22 Using an AC source to power the ICRI This power supply consists of two parts: (a) a three-prong AC power cable and (b) an AC to DC converter with an interconnect cable. Note: The AC supply must not be used where the cables or converter can become wet. Connect the power cord to the converter and to the AC source ( V, 60Hz). 22

23 Connect the other end of the assembled cable to the ICRIs rear panel jack labeled DC INPUT. Note: Care should be taken to align the arrow on the plug with the arrow on the jack before attempting to insert the plug. To remove the locking plug from the ICRI, hold the fluted part of the plugs barrel and pull straight out. Note: Do not attempt to unscrew the plug! 23

24 MULTI-FUNCTION POWER SWITCH This three position switch is used to turn the ICRI ON and OFF whether the ICRI is to be powered by the internal, rechargeable battery, or an external power supply. 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/center position is OFF. 24

25 Land Mobile Radio Interface Before connection to ICRI Verify radio operation and battery charge level Radio Settings Verify all radios/phone are in Secure mode, if required Channel selection for Inter-agency communications Select interface cable NOTE: Radio interconnect cables are generally specific to a commercial radio brand and model, although some manufacturers use the same connector for several radio models. Interconnect cables provided by C-AT have a seven digit part number label on the cable. 25

26 Land Mobile Radio Interface NOTES: Connecting each radio separately to the ICRI and using the provided handset allows you to verify the radio is functioning before connecting the next radio. A radios internal speaker will be disabled when the interconnect cable has been attached, so you must use the handset, or a second radio on the same channel to verify the communications link. Attach interface cable Set volume control to mid-position between fully CW and fully CCW Verify VOX LED lights as voice is received at the radio 26

27 27 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 o ) turn to release the locking mechanism. Then, holding the metal barrel of the connector, pull the connector straight out of the jack.

28 TELEPHONE INTERFACE This jack supports the connection of the ICRI to a land-line telephone through the telephones handset wiring (using the coiled cord between the telephones base with touchpad and the handset) or the 3.5mm jack on a cell phone (using C-AT interconnect cable P/N ). A phone connected to the ICRI will be used for dialing and other keypad functions since the speaker and microphone functions are disabled. Use the ICRIs handset to talk/listen to the remote individual, if using the ICRI as a base station. 28

29 Use the telephones handset cable by unplugging the coil cord from the bottom of the handset and connecting to ICRI. Place the telephone handset back in the cradle until an in- coming call is received or an out-going call will be made. If the telephone permits conference calls to be setup, then all parties to the conference call can bee connect to the ICRI. Telephone Interface – Land-line * * Secure (STE) or non-secure (analog or digital) 29

30 When connecting to a cellular telephone using the interface cable, P/N , insert the 3.5mm (1/8) plug into the headset jack on the cellular telephone. Be sure it is fully pushed into the telephones jack. Set cell phones speaker/earphone audio to a mid-level setting following the cell phone manufacturer's instructions. The cell phone should be in the "auto answer" mode. See phone's instruction manual for the procedure. Dial a remote telephone or wait for an incoming call from another telephone. To receive an incoming call, the phone must be set to auto answer, or an individual must be available to answer the phone by pressing SEND or equivalent. If the cell phone permits conference calls to be setup, then all parties to the conference call can bee connect to the ICRI. Telephone Interface – Cellular * *secure or non-secure 30

31 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. Make sure to properly align the pins of the plug before inserting into the jack. After the plug is fully seated on the jack, the locking ring on the plug should be turned clockwise until the ring cannot be turned further. 31

32 Adjusting the handset/headset volume The audio level to the handset speaker can be adjusted by the rotating the volume knob above the jack. Counterclockwise decreases the audio level, and clockwise increases the listening level. Set the audio level to mid position. The handset microphone is enabled when the push-to-talk bar in the center of the handset is depressed and held down while speaking 32

33 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. The Unit/Voice ID is also transmitted each time the ICRI is turned on. If needed, this function can be disabled. This ICRI has a two position switch on the rear of the ICRI. Switch position Left: BRIDGE ID ON Switch position Right: BRIDGE ID DISABLED/OFF After switching the ID message off or on, turn off the ICRI momentarily and then turn it back on---this resets internal circuitry. 33

34 ICRI-to-ICRI LINK Connect the supplied cross-over RJ-45 cable, p/n *, between two ICRIs. Operate the ICRIs as normal. It is not necessary to power off or restart the ICRIs after connecting/disconnecting the link cable. Radios connected to the ICRIs will all be bridged together, when the link cable is connected. The distance between ICRIs cable can be extended by connecting a commercially availability CAT5 cable between one end of the cross-over cable and one of the two ICRIs to be linked. 34 * A standard CAT5 cable will not work.

35 Interoperability DOs and DONTs These simple universal rules will help to ensure that the part of communications interoperability will work properly. Verify that only one interoperability bridge in the area is using the radio frequencies that you will be using. Audio and RF cables should be separated from AC power cables by 12 (use an external DC source or batteries when you cant maintain the separation). Some bridge cables contain in-line, audio amplifiers for radios* designed with low audio levels. It is best to rout those cables away from radio antennas and connectors---lots of RF and distort the audio amplifiers output to the bridge. * Harris TM - M/A COM TM P7100, P7200, P

36 When plugging in two or more radios within the same radio band (i.e. FAMS VHF radios) into a radio bridge, you must provide as much vertical separation as possible to reduce the chance for interference due to the transmitted signal from one radio reducing the receive sensitivity of the other in band radios. Use external antennas with 25 cables connected to the radios (Sti-Co TM model MGNT-FT-NITI, you will need to have the antenna tuned to the frequency of the radio). 36

37 Dont use SCAN mode for any radios connected to a radio bridge. This is particularly important when you are using the bridge as a tactical repeater, where two or more radios have similar channel programming. If both radios are capable of hearing the same signal, they will key each other up "ping- pong", interfering with the function of the bridge. 37
