7.3.2 Unit Select/Deselect
Description
Command is used to select the PTU to be controlled. A PTU controller will
execute incoming host computer commands only when the preceding unit_ID
selected by the host is (a) equal to the PTU controller’s assign unit ID, or, (b)
equal to 0. A host computer can broadcast instructions to be executed by all
PTO controllers using unit_ID=0. Only one PTU controller can provide
feedback to the host computer at a time. A PTU controller provides feedback
to the host computer only when the host computer has selected its unit ID. A
PTU controller buffers its outgoing data until the host computer polls it -- the
current PTU controller buffer size is about 100 bytes.
Syntax
Select a PTU controller for bi-directional data: _<unit_ID><delim>
Broadcast to all networked PTU controllers: _0<delim>
where 0 ≤ <unit_ID> ≤ 127
Example
