Reply:
The reply generated will be either response to the data sent to the unit, as in
a query, or an error code. The error code will be prefaced by a ‘#’ and then
the ascii code itself. The codes are explained below. The error code, whether
it is 0 (which indicates NO ERROR) or a valid error is prefaced by the ‘#’
character to distinguish the data from a valid reply. For example, if the pulse
width was queried (CHNx:PULS:WIDT?), a valid response would not have a
‘#’ character as the first character, but if there was an error (such as invalid
channel, parse error, etc.) the response would send a ‘#’ character as it’s first
byte.
The ASCII commands:
The commands sent are in four letter words separated by a colon. The data is
separated by a single white space character (0x20) and is in the from
x.xxE+xx. For example, to set the frequency to 1.35 KHz you would send the
string CHAN:PULS:FREQ 1.35E+03. Each channel in the unit is distinguished
by a CHNx, where x is the channel the remote is talking to. For example, to
set the pulse width of channel 2 to 150 us, the string sent would be
CHN2:PULS:WIDT 1.50E-04.
