Host Commands Using RS-232 or RS-422
7–7
Command:
DD
Function:
Set decoder to default configuration.
Response:
=00CRLF
Note: Host communication port parameters and the contents of the EEPROM
are not changed with this command.
Command:
HCaaannnssspppfr
Function:
Set host communication parameters.
Response:
=rr
Comments:
HC = Set host communications command.
aaa = ACK (positive acknowledgment) character.
Must be ASCII decimal value from 000 to 254. A
value of 255 = None.
nnn = NAK (negative acknowledgment) character.
Must be ASCII decimal value from 000 to 254. A
value of 255 = None.
sss = start scan character. Must be ASCII decimal
value from 000 to 254. A value of 255 = None.
ppp = stop scan character. Must be ASCII
decimal value from 000 to 254. A value of 255 =
None.
f = large buffer enable
1 = YES
0 = NO
r = selects response mode
0 = End of Trigger
1 = After Valid Package
rr = response code, refer to table on Page 7-3.
Note: The ACK/NAK, start scan, and stop scan characters will not be
entered into the operating system until the configuration is saved to
EEPROM and the decoder is restarted (ESC = ! RN). After setting new
ACK/NAK characters, the host must begin sending the new characters with
each transmission.
