2-46 Standard Configurations Microphone Hang-Up Clip

2.6 Microphone Hang-Up Clip

2.6.1 Standard or O3 Control Head Hang-Up Clip

The hang-up clip must be within reach of the operator(s) and close enough to the control head to prevent cable strain. Measure this distance before actually mounting the bracket. Since the bracket has a positive-detent action, the microphone can be mounted in any position.

Use the hang-up clip as a template to locate the mounting holes. To avoid interference when removing the microphone, install the flathead screw in the top clip hole.

Some microphone models require the grounding of the microphone clip in order for HUB operation to work correctly. Refer to the documentation that comes with your Motorola microphone model.

NOTE: For multi-control head configuration where only one of the control heads has a microphone,

the control heads without a microphone attached must have their HUB or Monitor pin (J100-22) jumpered by a wire to GND (J100-1 or J100-14) for HUB operation to work.

2.7 RFID (Option)

An APX mobile radio equipped with an RFID tag allows an alternate option for tracking the radio asset. Each RFID equipped radio has an RFID tag preprogrammed with the individual radio’s serial number (also found on the FCC label) as well as band and radio model information (see below for further info).

2.7.1 RFID Reading

To read an RFID tag using a UHF Gen 2 RFID reader (e.g. Motorola’s MC9090-G), open an appropriate RFID read application, point the RFID reader at the tag and activate the reader's RFID antenna (e.g. pull Motorola’s MC9090-G scanning trigger). RFID reader must be within 1 foot from tag in order to read.

Two variables, Read Angle and Reader Orientation, aid in the distance needed to read and write to the RFID Tag. Read distance is independent of Tag Angle, but the reader should be as close to perpendicular to the tag as possible (Read Angle).

As Read Angle increases past 60 degrees, read distance will begin to decrease; tag will become unreadable once Read Angle exceeds 90 degrees (see Figure 2-64 and Figure 2-66). RFID tag cannot be read through metal. The orientation of the reader (Reader Orientation) and the tag must be aligned to improve read and writability (see Figure 2-70).

Chapter 3 Universal Relay Controller Installation

The Universal Relay Controller (URC) is an extension of and an orderable accessory for O7 or O9 control head. URC is used to control high power switching peripherals, e.g. lightbar. URC works on all lightbars which can be controlled by power application. URC is connected to the transceiver's GCAI port.

The URC design consists of a microcontroller and uses 10 relays to control the switching device. A separate ground for isolation exists between the relay and MCU sections, which is provided by the use of iCoupler from Analog Devices. Each relay is connected to an output with 15 A fuse. The maximum load allowed on each output is 12 A. Two cables, each with the maximum of 60 A, can be used to connect to the input connector at the bus bar. Each cable is connected with a 60 A circuit breaker. One-wire EEPROM is employed to enable GCAI to recognize the URC accessory ID. CPS can be used to program the relay patterns.

When installing URC, make sure to plan the installation carefully and leave additional room in the front and rear of the box for cabling and accessory connections; and also to the sides of the radio so that you may access and install the trunnion screws.

The recommended mounting location for URC is in the car trunk, either next to the transceiver or within the area not further than 4.5 m away from the transceiver. Ensure that sufficient cooling is provided. Do not cover URC with baggage, blankets, etc.

C a u t i o n

Do not backfeed power into URC.

3.1 Universal Relay Controller Mounting

The mounting location must be accessible and visible. Select a location that permits routing the cable as directly as possible.

NOTE: For optimum URC performance, orient the mounting trunnion as shown in Figure 3-1.

Figure 3-1. Universal Relay Controller Orientation

An adjustable trunnion, which allows a number of mounting positions, is supplied for mounting the URC. The installation must not interfere with the operation of the vehicle or its accessories.

3-2 Universal Relay Controller Installation Universal Relay Controller Mounting

Install the URC as follows:

1. Use the URC trunnion as a template to mark the mounting holes; drill 5/32" holes. If mounting on a plastic surface, use a metal backing plate.

2. Attach the trunnion bracket using all four 10 – 16" x 5/8" self-tapping screws provided.

3. Temporarily install the URC (adjust for proper viewing angle) and fasten it to the trunnion with two wing screws. Test the installation to ensure that the unit is securely locked in place.

3.2.1 Power Cable

1. Remove the cap nut of power cable gland assembly, and insert the power cable through the cap nut and neoprene seal in the cable gland body. Use power cable with either AWG 6 or AWG 8 only (recommended OD range of cable is 5.5 mm to 9 mm) that is able to withstand 80 A and 50 A respectively, to ensure water sealing of the controller. User can decide to install one or two power cables based on the requirements. The power cables (A+) are not supplied.

2. The loose end of the power cable with cable strip length 7.94 mm (5/16”) is then placed on the power lug and secured down by a set screw. The cap nut is then reassembled with tightening torque 18 lb-in.

3. The other end of the power cable should be connected to circuit breaker (Motorola part number 40012006001) end which indicates "AUX" and then, to power supply on the other end which indicates "BAT", instead of connecting to power supply directly.

4. Repeat steps 1 to 3 to install the second power cable, if required.

5. If only one power cable is installed, it is recommended to cover the other side of the power cable gland with power cable gland seal with tightening torque 18 lb-in.

3.2.2 Ground Cable

1. Remove the cap nut of ground cable gland assembly, insert the ground cable through the cap nut and then reassemble the cap nut. Use ground cable with AWG 14 only (recommended OD range of cable is 2 mm to 4 mm) that is able to withstand 5 A. The ground cables (A+) are not supplied.

NOTE: The ground is used to switch the relays, and not act as a ground to the actual device being

controlled.

2. The loose end of the ground cable with cable strip length 7.94 mm (5/16”) is then connected to a two-pin terminal block. Both pins on the terminal block are inter-connected and either pin can be used. The cap nut is then reassembled with tightening torque 7 lb-in.

5. The lightbar gasket should be replaced at each reassembly of the wire.

NOTE: Use of other cable gages except as recommended in this manual may result in water

intrusion. Any reassembly of wire needs a new lightbar gasket replaced. If the current loading for one wire is higher than 12 A, the wires should be splitted before being assembled to the URC system. Wires kit (PMKN4109_) is provided to ease installation of the URC. Incorrect use of the wires kit, e.g. improper connection at external loose end wires, may impact the robustness of the URC.



Remove the wires and gasket residual inside the URC after the wire installation, before closing the top housing of the URC.

3.2.4 O7/O9 to URC Cable

The O7/O9 to URC cable (Motorola part number 3064153H02) can be assembled either before or after reassembling the top housing. Assemble the RJ45 port of the cable into the RJ45 connector on the URC and turn the locking collar instead of cable, 90 degrees to the right to ensure it is locked properly. After that, test whether the cable is locked properly or not by trying to pull out the cable.

4.2.1 Emergency Pushbutton or Footswitch Installation

Mount the switch using the hardware that comes with the kit. Connect the button/switch wires to a ground pin and the emergency pin, removing the default jumper wire in the rear accessory cable. The button/switch will short the pins when in-active. When the button/switch is pressed, its contact opens, the emergency path is un-ungrounded and pulled-high inside the radio transceiver, and detected by the processor. If an emergency accessory is used at either (or both) J2 connector and J626 connector, all jumper wires, shorting emergency to ground, must be removed so button/switch press can be detected.

In additional to removing the default jumper wires in accessory cables, you must also remove a jumper part on the printed circuit board of the TIB, in order for the button/switch to be detected. On the TIB PCB (both mid power and high power use the same TIB) a zero-ohm jumper is placed by default so that the radio does not go into emergency when no cable is attached at either J2 or J626 in remote mount configuration. This jumper part, JU344, must be removed if either or both J2 and J626 will have any type of emergency cable and button/switch attached. Otherwise, the processor will never see emergency become un-grounded.

4.2.8 USB Data Cables

It is recommended that the USB 1.5 meter data cable HKN6163_ is used for both dash mount configurations (at J2 connector) and for remote mount configurations (at J100 connector). This is because the HKN6163_ has the emergency jumper present, which is necessary for correct dash mount configurations. For interfacing at the MMP port, use Cable HKN6184_ which is a USB device cable.

The USB 4 meter (15 feet) data cable enable HKN6172_ is recommended for remote mount configurations only (at J100).

If the customer intends to use the HKN6172_ for dash mount configurations (at J2), the cable’s  26-pin connector must be opened and an emergency jumper-wire placed across pins 14 and 15. Refer to Figure 4-1.

4.2.9 RS232 Cables

The following are RS232 cables. Although not compatible with CPS radio reading or programming, they can be used for interfacing with RS232 accessories or RS232 computer programs. HKN6122_ is an RS232 serial COM port computer interface cable from J600 connector. HKN6160_ is a 6 feet dash RS232 cable from J2 connector. HKN6161_ is a 20 feet dash RS232 cable from J2 connector.

The VIP output pins are on the back of the control head (J100 and J400), or the rear accessory port (J2), as shown in Figure 2-10, Figure 4-12 and Figure 4-13, respectively. Use these connections to wire control relays. One end of the relay should connect to switched B+ voltage, while the other side connects to a software controlled ON/OFF switch inside the control head. The relay can be normally on or normally off depending on the configuration of the VIP outputs. There are three VIP output connections, as follows:

The function of these VIP outputs can be field programmed in the control head. Typical applications for VIP outputs are external horn/lights alarm and horn ring transfer relay control. For further information on VIP outputs, see the control head programming manual.

VIP OUT 1 and VIP OUT 2 can be accessed from either J100 or J400 connectors. This is to allow a previously wired VIP OUT at J2 to move easily to J100. However, when any cable is inserted into J400, J100 VIP OUTs are disabled.

When installing relays to the VIP OUT lines, a diode is necessary to prevent damage to the transistor or MOSFET, due to “back EMF” when the field collapses on the relay coil. Some vendor relays already come with this diode built-in, and other relays require the customer to install it. Figure 4-8 shows the proper placement of the diode across the relay coil. The transistor or MOSFET is located inside the radio or the D.E.K. box.

Note: To 'activate' a VIPOUT, you have to ground the VIPOUT, such that the current now flows thru the relay coil to GND through a MOSFET inside the radio or control head, which causes the relay wiper to toggle. The MOSFET of a VIPOUT should never be used to directly drive an accessory. The MOSFET should be used to control an external relay.

Example relay hardware: TLN4533_ (relay without internal diode), HLN6969_ (relay with internal back EMF protection diode), and HKN4258_ (relay wiring cable).

4.3.2 VIP Input Connections

The VIP input pins are only available on the back of the control head (remote mount). These connections control inputs from switches. One side of the switch connects to ground while the other side connects to a buffered input on the control head. The switch can be normally closed (NC) or normally open (NO) depending on the configuration of the VIP inputs. There are three VIP input connections, as follows:

MCH installations require the VIP inputs to be connected to the head assigned ID #1. See

Section 2.2.2.5: “Setting the Initial Control Head ID” on page 2-29 for further information.

APX mobile radios equipped with the following features are capable of transmitting automatically, even if the radio is turned off:

C a u t i o n

All APX mobile have accessory connector pins 14 and 15 connected together to allow the radio to power down. Opening this connection by REMOVING the accessory connector, or otherwise failing to maintain a normally closed path, could, if left unchecked, drain the vehicle battery, and possibly cause transmissions to occur.
