Data Entry Protocol:
The serial buss should follow a standard serial communications protocol using Line oriented ASCII data stream. The command line must be followed with a carriage return for the unit to respond. The unit should not echo characters received back to the host.

Command Codes:
Character X: T: B: P: F: A: M: S: Q: N: L: Range 0,1 1,2 1,2 00 - 30 4 numbers 0,1 0,1 Signal Lock / Stereo Presence Query status of tuner 0,1 01 - 30 Function Power Off / On Tuner # Band # Preset # Frequency Setting Seek Up / Down Step Up / Down 1 = locked, 0 = not 1 = stereo, 0 = mono ask for tuner status Preset Step Up / Down Set Preset X1 = Power On, X0 = Power Off T1 = Tuner 1, T2 = Tuner 2 B1 = AM, Band 2 = FM P01 = Preset 1, P30 = Preset 30, P00 (just for status) = No Preset Selected F0890 = 890 AM, F1045 = 104.5 FM A0 = Seek Down, A1 = Seek Up M0 = Step Down 1 step, M1 = Step Up 1 step S00 (just for status) = no signal, no stereo, S01 = invalid S10 = signal lock (mono), S11 = signal lock (stereo) Q1 = Status of Tuner 1, Q2 = Status of Tuner 2 Q3 = Status of both tuners, 1 then 2 N0 = Step Down 1 Preset, N1 = Step Up 1 Preset L01 = Set Station as Preset #1 Example

Command Examples:
T1B2P01<cr> would command tuner #1 to select band 2 (FM) and tune to FM preset #1 T2B1F1070L03<cr> would command tuner #2 to set AM frequency 1070 kHz as AM preset #3 This command however, would not change the current station tuned on Tuner #2 To select a station to be tuned and THEN set that station as a preset, would require two commands: T2B1F1070<cr> would command tuner #2 to select band 1 (AM) and tune to frequency 1070 kHz. T2L03<cr> would command tuner 2 to set the currently tuned station (in this example AM 1070) as AM preset #3

Query Example:
Q1<cr> would solicit the following response: Feedback as to the status of tuner #1, which would include band select, station preset, frequency tuned, signal lock and stereo presence. The response string would look like this:T1B2P00F1011S11 T1 (tuner 1) B2 (FM), P00 (no preset selected), F1011 (frequency 101.1 MHz), S11 (signal lock & stereo)

Shortcut Commands:
Note: examples below are assuming Tuner 1 is in FM stereo mode and tuned to a station Command Response/Action T1N1<cr> Tuner 1 would step up to the next higher preset number T1L01<cr> Tuner 1 would set the currently tuned station as FM preset #1 T1S10<cr> Tuner 1 would switch the FM mode to mono T1M1<cr> Tuner 1 would step up the frequency 0.2 MHz T1A0<cr> T1B1<cr> Tuner 1 would go into "seek down" mode Tuner 1 would go to AM mode and tune to the last previously tuned AM station
