Polling Auto Designation (PA)
A polling auto designation causes the ID Controller to return a response indicating reception of a poll-
ing command and then perform the operation for a single auto designation (SA). The ID Controller
does not return a response until it receives the POLLING QUERY command (PC) (see note 1). The
POLLING QUERY command (PC) (see note 2) is also used to cancel processing.
Note 1. A process designation of C is used to request the response.
2. A process designation of E is used to cancel polling.
