Timeout Descriptions
The IMM, SIM, and the 39
plus
-IM have timeout algorithms.
For
IMM timeouts
, see the IMM manual.
SIM timeouts
restore control to the computer if no reply is received from the
IM instrument (for example, upon sending an illegal command) within a
specified length of time. This allows new commands to be sent. There are two
user-programmable SIM timeouts that are applicable for use with the
39
plus
-IM:
•
DataNNMax=
timeout for
!iiData
and
Dataii
only.
Default 1000 millisec.
•
RelayMax=
timeout for all other commands. Default 20 sec.
Control of the SIM can be re-established sooner than the timeout by pressing
the Esc key and then the Enter key. When control is reestablished, new
commands can be sent.
The 39plus-IM timeout
powers down the 39
plus
-IM communication circuits
if the 39
plus
-IM does not receive a command for 2 minutes, to prevent battery
pack exhaustion.
To re-establish control:
•
Select
Connect
in SeatermIM’s Communications menu, or
•
(if using SIM) Send
PwrOn
, or
•
(if using IMM) Wait at least 1 sec, send
ForceCaptureLine
, and then
send
SendWakupTone
.
