7.3.2 Unit Select/Deselect

Description

Command is used to select the PTU to be controlled. A PTU will execute

incoming host computer commands only when the preceding unit_ID

selected by the host is (a) equal to the PTU’s assign unit ID, or, (b) equal to 0.

A host computer can broadcast instructions to be executed by all PTUs using

unit_ID=0. Only one PTU can provide feedback to the host computer at a

time. A PTU provides feedback to the host computer only when the host

computer has selected its unit ID. A PTU buffers its outgoing data until the

host computer polls it -- the current PTU buffer size is about 100 bytes.

Syntax

Select a PTU for bi-directional data: _<unit_ID><delim>

Broadcast to all networked PTUs: _0<delim>

where 0 ≤ <unit_ID> ≤ 127
