8-2. CONTROL COMMAND
The following is an explanation of the formats and kinds of control commands which are output to the WGA-910A
from external equipment such as PC.
Sets the control command that is output from the external device to WGA-910A.
(1) Outline of the control command
1) Control command code
・Control command conforms to ASCII code (3 capital letters).
・According to the command characteristic, some control commands are suffixed by parameters.
・A termination code is added to the end of a control command.
Different termination codes are used as follows.
<CR>:
<CR><LF>: Data output from the WGA-910A.
・If an unrecognizable command or number is input and if the decimal point position of the calibration value is
incorrectly input, the character string of that command is returned in the following format.
W
・If an error happened when writing the setting value to the EEPROM, the following format is returned.
ng<CR><LF>
2) About delimiters
・Added to the end of the control command.
・Different delimiters are used as follows.
<CR>:
<CR><LF>: Data output from the WGA-910A to the external equipment.
