General Info

Unless otherwise noted all valid commands are echoed back if properly received unless the “***”

address is used.

When Main TV or FM channel is changed via remote or contact closure, the RS232 is updated by

sending a ~MCHxxx<CR> or ~FCHxxxx<CR> response as long as the address is zero.

When Volume is changed via remote or contact closure, the RS232 is updated by sending a

~VOLxx<CR> response

Invalid commands will reply with ~ERROR<CR> as long as the address is zero.

Convert the multi-digit ASCII decimal representation response to a true hexadecimal value. Ex. xx =

13 (0x31, 0x33) turn this into 0D. The bit information is once the ASCII to hexadecimal conversion

has been done.
