The radio can be used nor-mally with ‘auxiliary off’, and line controlled with ‘auxiliary on’.With ‘auxiliary on’, the line output mute elements and opto driver are controlled fromthe RX-GATE. A signal on the BUSY line inhibits the transmitter line key circuitry. Linederived key signals, such as OPTO-IN, KEYING and PTT-IN, can be used to key theradio, provided the auxiliary control is on and the radio is not busy.The KEYING line is used for back-to-back control of two radios, each with a line inter-face PCB. This enables crossband linking to be achieved with a minimum of external cir-cuitry. In this case, the KEYING line can be linked to the OPTO-IN line on each unit,with a wire between the two OPTO-IN lines providing bi-directional control. KEYING iscontrolled by the receive gate and is used to drive the opto input of another line inter-face PCB.The opto input is intended to be connected to the output of an optocoupler circuit (BJT)used for loop and tail keying via transmission lines (refer to Section 8.14.6, “Applica-tions”).The opto output is intended to be connected to the input of an optocoupler circuit (LED)used for loop and tail keying via transmission lines (refer to Section 8.14.6, “Applica-tions”). The sense of this circuit can be changed by a link.An adjustable time delay circuit is available to prevent transmitter cycling when cross-band connected radios are both operating on repeater channels. The circuit is adjustableto approximately 1.5 seconds, with the time delay control fully clockwise, and can bedisabled completely by removing a link.PTT-IN can be used to key the transmitter. Links are available to enable either logicsense. For trunked versions using modems, a circuit is provided to set up a call automat-ically.Control logic for telemetry and modems is provided so that the radio can be operatedautomatically. IN-LOCK-OUT, BUSY/GATE and TX/RX-OUT outputs can be set bylinks for either logic sense.Trunked modems operate in a different manner, and first have to set up a call to obtain atraffic channel allocation.Logic is available which requires several link changes, as some of the radio options con-nections perform different functions:Standard TrunkedAUX on/off not clear to sendemergency external call requestcall traffic channel allocated

Commandsare generated by the DTE, and responses or unsolicited messages returned by the RU.There is a prescribed format for all messages, which allows transmission errors to bedetected.Control of the RU is accomplished by the DTE sending a command sequence (a“packet”) and receiving a response (a “transaction”). Unsolicited messages may origi-nate from the RU.The RU will issue a prompt character to indicate to the DTE that it is ready to accept anew command. After issuing a command, the DTE must wait for another prompt beforebeginning the next transaction. The prompt character is “•” (full stop, ASCII code =$2E).Messages directed to the RU will always be responded to, either explicitly by means of areturn message (“Ready” or “Error”), or implicitly, by just the prompt “•” being issued. The RU will not originate a message: messages returned by the RU are for informationpurposes only, and no reply will be expected from the DTE.This protocol definition is based on the T2000 CCI protocol, with specific extensions tosupport binary data transmission and reception.

[SIZE]is an 8-bit number expressed in ASCII-hex notation (two characters).[PARAMETERS] An optional field, depending upon the command. Parameter values are generally character strings, unless explicitly stated otherwise. Parameter type is dependent upon the command - there is no explicit type definition.[CHECKSUM] An 8 bit checksum of fields [IDENT],[SIZE] and [PARAMETERS].

The signal is demodulated in IC1 and the data fed intothe microprocessor, IC2. The data, complete with its length & checksum information, isfed to the DTE via IC4, which converts the 0V/5V TTL levels to RS232.On transmit, data is sent from the DTE to IC2, via IC4. It is processed and sent on to IC1,where it is modulated and the output goes to the TX-SIG-IN input of the radio, via aunity gain buffer, IC6. IC2 also monitors inputs from the radio’s logic PCB and controlsvarious output lines.The microprocessor checks that the radio is in lock, and is not busy. It then mutes themicrophone, activates the radio PTT and 30ms later, the PWR-CTRL signal goes low,releasing the transmit inhibit.Both buffer amplifiers are biased at half rail by IC1, pin11.If a channel change is required, the data is sent to IC7, which toggles the appropriateBCD lines to change the radio channel.
