Model HR-731-S
6.3 RS-232 Control Commands
All commands are prefixed with ==>
All commands and responses are followed with a carriage return
Wrong commands will get a response of ERR1
Not-allowed commands in CEC mode will get a response of ERR2
Command:
SBn stands for Set Baud of remote unit
where n=(0-7,?)
(0 = 1200, 1 = 2400, 2 = 4800, 3 = 9600, 4 = 19200, 5 = 38400,
6 = 57600, 7 = 115200, ? = query baud rate)
Response:
SBn
Condition:
This command can only valid when the data channel is set to RS-232. If this
command is issued in CEC mode, the HR-731-S responds with ERR2
Command:
SPn stands for Set Parity of remote unit
where n=(0-2,?)
(0 = none, 1 = odd, 2 = even, ? = query Parity)
Response:
SPn
Condition:
This command can only valid when the data channel is set to RS-232. If this
command is issued in CEC mode, the HR-731-S responds with ERR2
Command:
STn stands for Set Terminating byte/character
where n=(0-255,?)
(0 = none (default), 1-255 = Terminating character (or byte) has
a decimal value of n , ? = query Terminating byte)
Response:
STn
Condition:
This command is only valid when the data channel is set to RS-232. If this
command is issued in CEC mode, the HR-731-S responds with ERR2
Comments:
Normally in RS-232 mode, every character received is immediately
transmitted to the opposite side. By specifying a Terminating character, the
device will keep all the data received in a buffer and transmit the entire
string at once upon receiving the terminating character (including the
terminating character). For example: to wait for a Carriage Return before
sending the string, use n=13 (since CR=0D Hex, or 13 Decimal).
Command:
DCn stands for Data Channel configuration
where n=(0,1,?)
(0 = RS-232, 1 = CEC, ? = query Parity)
Response:
DCn
Command:
FD stands for Factory Default
Factory default settings will be restored
Response:
FD
Command:
FW? stands for Firmware Version query
Response:
FW Version #
