NOTE: Upper and lower case characters can be used interchangeably in SIS
commands for this product.
The X/ values defined in this section are the variables used in the fields of the command
and response table.
X! — 0 to 100: Volume level steps (0 = mute)
X@ — Status (0 = Off or Disable; 1 = On or Enable)
X# — Relay pulse time (in 20 milliseconds increments) from 12 to 65535. For example,
the minimum value (12) is equivalent to 12*20 = 240 ms. The maximum value (65535) is
equivalent to 65535*20 ms, which is 1310 seconds.
X$ — 0.00 to 10.00: Maximum output voltage or resistance (kilohms).
NOTE: The final 0 must be used, for example 8.50 (8.5, without the 0 will return an
error). The leading 0, for example 08.50, is optional.
X% — Sets control mode (0 = potentiometer; 1 = voltage)
X^ — Sets volume taper mode (0 = linear; 1 = logarithmic)
X& — Firmware version number (in the format: x.xx)
X* — The unit name is an alphanumeric string of up to 24 characters that allows the user
