C-3-2 Command Addressing
Each Model 0254 unit is assigned a unique 5-digit address, from 0 to
65535, which must be pre-programmed in the instrument prior to
deployment in a networked system. The ports that comprise a channel are
designated with an appended [.x} or [.xx] sub-address.
The 5-digit address may be omitted when operating a single un-networked
unit, but must be used in multiple unit networks to differentiate the units
from each other.
Command arguments are single ASCII alpha non-case sensitive
characters. No spaces are allowed between the 'AZ' and <cr>, i.e. start and
respectively the end of the command.
