CONTROL COMMANDS FOR TERMINAL SOFTWARE
The SR2200 is operated via PC using the RS232C, or USB port. The commands necessary to
that effect, are described in this chapter.
Microsoft Windows Hyper Terminal may be used to control the SR2200, or you may use your own
software by integrating the following commands.
Communication parameters
• Baud rate 38400 BPS
• Data length 8 bits - ^A nn [cr],[LF]  ^A = 13 Hex  nn = Receiver's ID #
• Stop bit 1 bits If ID # = 00 (DEFAULT VALUE), command can be input directly.
• Parity NONE
• Flow control NONE
• Local echo ON (set in ASCII settings of Microsoft HYPERTERMINAL)
Delimiter
■PC → SR2200
<CR> （0x0d）
or
<CR><LF> （0x0d 0x0a）
Note: <LF> will be ignored
■SR2200 → PC
• “OK”response when the command has been correct:
<SP><CR><LF>（0x20 0x0d 0x0a）
• Response when the command has been incorrect:
？<CR><LF> （0x3f 0x0d 0x0a）
• Response to the read command:
Following the output of the parameter, the correct response should read:
<SP><CR><LF>（0x20 0x0d 0x0a）
Numerical parameter auto-correct
The SR2200 does correct the numerical command parameter to the digit format applying to the
given parameter. In the following example, the DB command has to be followed by a 3-digit
number.
Ex.: DB003 <CR>
The SR2200 will add one or two “0” in order to achieve three digits.
