To successfully send a command do the following:
The commands should be sent exactly as shown (case sensitive) with no spaces between characters. The
ACK command is sent as three ASCII characters, ACK in sequence. ‘A’’C’’K’ .
Note that the TS (transmitter) devices send data ‘over air’ as they are not equipped with a serial data out or
handshake pins. This takes approximately 20mS and time should be taken in to account before sending the
‘ACK’ sequence
“FAST ACK”
In this mode the procedure to update settings is made much faster. In response to an ER_CMD#x string the
TRS/RS module will reply with a single HEX 6 (0x06) which is the ASCII ACK value. The host will then issue
the same single byte 0x06 in replacement of the Txt version of “ACK”.
