AutoTrak II Audio User Serial Command Set: 

The EasyTalk AutoTrak 2.0 Wireless Audio Interface has an RS-232 command interface for configuration and 
real-time control.  This interface can be used interactively with a serial terminal emulator, or through a scripted 
interface without terminal emulation (command echo and prompt).  DIP switch 7 on the Receiver unit controls 
whether configuration commands are enabled on the serial interface (switch in the up position), or whether the 
configuration is controlled exclusively from the DIP switches (switch in the down position).  Real-time control 
commands are always available over the serial port. 
 
Command echo and prompt can be enabled or disabled with the 6121 command.  When enabled, commands 
input to the receiver are echoed back, and a '>' prompt character is output whenever a carriage return is entered.  
When disabled the echo and prompt characters are suppressed. 
 
For all commands, the termination character is a carriage return (hex 0D).  Response strings output by the 
Receiver will end with both a carriage return and a line feed (hex 0A).  Input line feed characters are ignored. 
 
 “Set” commands return one of three responses: OK (4100), bad command (4199), or bad parameter (4198).  
“Get” commands return a response string indicating the command being responded to and the data requested.  
The format of a “get” response is a 4-digit response code, a space, and a two-digit hex value
