When a successful SET, SETL, INC, DEC, or RECALL command is sent to an E Desk
device via RS-232 or Telnet, E Desk will respond with: ‘+OK’ followed by a carriage
return and line feed.
Example: Sending the string: SET 2 AMLVLIN 4 2 1< LF> will result in an:
+OK<CR><LF> response.
A successful GET or GETL command will result in a numerical response to the
command string followed by <CR><LF>.
The response from an ETP string with a GET command may contain a decimal
point (with 4 numbers after the decimal) and/or negative numbers, depending on
type of A
ttribute addressed. If the control system does not support negative
numbers or decimal places a GETL command may be used instead (see page
6).
Example: After sending the above example to an E Desk device the string:
GET 2 AMLVLIN 4 2<LF> would result in the response: 1.0000<CR><LF> this tells us
that the level is currently set to 1dB.
If an incorrect command string is sent, an E Desk will respond with: -ERR <CR><LF>
