Motorola used to make a Spectra programming adapter for this function that plugged into the microphone jack, that I do not have a part number for. The Astro Spectra can be identified by a W3, W4, W5, W7 or W9 control head designation, or the Astro logo on the radio or control head. The Spectra product line uses the serial bus from the Syntor X 9000 radios. Fuse Assembly for Yellow and Red Leads Parts List.

The Radio Service Software and programming hardware is used to read, edit, save and write the radio's code plug. Measure this distance before actually mounting the bracket. Second, the very early and early will not work.
The code plug is like a program that runs under the radio's firmware based operating system. The Systems 9000 Housing cable is attached to the J6 connector. Interoperable voice signaling Complies with P25 standards. Sturdy ergonomic design Can take on rough weather and shocks. Tighten the screws firmly but do not over-tighten them. The microphone connector on the front of the control head is used. A2, A3, A4, A5, A7 and A9 are for conventional i.
B2, B4, B5, B7 and B9 are for trunking Privacy Plus Spectra radios. The J3 connector is not found on any cables. The title under each figure identifies the M5 control head configurations. Radios with these control head circuit boards could possibly program the radio's code plug using these connections with a custom cable. Choose a mounting location for the radio, considering accessibility, and control and antenna cable lengths. Radios with the external Securenet option board located outside the radio drawer in a have their own Keyloader Port on the housing, so these do not use P506.
There are some problems addressed below. Accidentally reversing the polarity will not damage the radio, but will cause the cable fuses to blow. Table 2-1 in Chapter 2 for wiring options. The switched B+ also goes to the radio drawer and wakes up the radio drawer microprocessor. Some vendor relays already come with this diode built-in, and other relays require the customer to install it. If you have a radio with one of these control head boards that will not power up, this could be one potential source of the problem. Remote Mount Configuration, with 110W transceiver For details on these configurations, see Section 2.
The standard speaker is 8 ohms. Term Definition See analog-to-digital conversion. Front View of Dash Mount Transceiver Trunnion.

Select the location to mount your radio on the transmission hump see Figure 2-13 or under the dash see Figure 2-14.
Normally, the J3 cable connector or Systems 9000 connector is used instead. Universal A microchip with programming that controls a computer's interface to its Asynchronous attached serial devices. Here are the original style and motorcycle Spectra remote mount control head hookups. Click on the hot spots above for the individual connector and cable pin outs that plug into the above connector. Some control heads have another microphone connector on the control head face. This system has a floating speaker output dc voltage on both leads ; damage to the audio circuit will result if either lead is grounded or if they are shorted together. This board also has an optional jumper to short the Emergency line to ground.
