Audio; Program Cable; Sb9600; Vip - Motorola ASTRO XTL 5000 Basic Service Manual

Basic Theory of Operation: Surrounding Controller Region

3.5.4.1 Audio

The audio circuitry of the controller section contains the following:
• Audio PA
• Codec
• MIC Audio
• DSP controlled EEPOTS
• AUX RX, AUX TX, and external speaker paths
• FILT audio.
This allows interfacing to the existing accessories made by Motorola, such as VRS, SIREN, and
Consolette. It also allows for select compatibility with aftermarket modems.

3.5.4.2 Program Cable

If the programming cable is used with a standard legacy control head, circuitry found in the controller
section provides the voltage-translated boot RX and boot TX communication paths, as well as the
cable-detection circuit.

3.5.4.3 SB9600

Just as on many Motorola products, an SB9600 communication bus exists on the XTL 5000 radio.
Hence, many Motorola SB9600 accessories are compatible with the radio. These lines include
BUS+, BUS-, Busy, and RESET. These lines are available at connectors J5 and J6.

3.5.4.4 VIP

VIP-IN and VIP-OUT lines are available at the front and two VIP-out lines are located at the rear.
Their purpose is to drive relays to control external logical devices, or to logically communicate
directly to the XTL 5000 microprocessor. Their most versatile usage is in conjunction with a DEK, but
this is not mandatory.
NOTE: Please see the VIP section of the ASTRO XTL 5000 700–800 MHz Digital Portable Radio
Detailed Service Manual for configurations and voltage level requirements.

3.5.4.5 RS232

UART_A can be selected as a standard 4-wire RS232 or 4-wire USB slave device. The UART_B is
defaulted to use SB9600 lines so that all legacy control heads and SB9600 accessories are
compatible with the radio.

3.5.4.6 One-Wire

One-wire technology is embedded in the radio for future compatibility with upcoming smart
accessories.
