3.
If this is the first time SeatermIM is being used, the configuration dialog
box displays:
Make the desired selections, and click OK.
4.
SeatermIM tries to automatically connect to the 39
plus
-IM. It sends
DS
to
determine if it is communicating with a SIM. If there is no response to
DS
, it assumes it is communicating with an IMM and proceeds as follows.
A.
It sends
GetHD
and
GetCD
to get IMM status information.
B.
If
ConfigType=1
, it sends
PwrOn
to wake up all IM instruments on
the line. If
ConfigType=2
, it sends
ForceCaptureLine
to reserve the
IM line by transmitting a carrier signal, and
SendWakeupTone
to
wake up all IM instruments on the line.
C.
The remaining connection attempt varies, depending on the ID
configuration setting the last time SeatermIM was used:
•
If SeatermIM was set to
Automatically get instrument ID
–
It sends
id?
and waits for a response from the 39
plus
-IM.
It then sends
!iiGetHD
and #
iiGetHD
, using the ID provided by
the 39
plus
-IM.
•
If SeatermIM was set to
Use fixed ID
– It sends
!iiGetHD
and
#iiGetHD
, using the fixed ID that was entered the last time
SeatermIM was used.
SeatermIM then fills the Send Commands window with the correct list of
commands for your 39
plus
-IM.
5.
If there is no communication
(no response to
id?
and/or no response to
!iiGetHD
and/or
#iiGetHD
):
A.
In the Communications menu, select
Configure
. The Configure
Communications dialog box appears. Select the Comm port and baud
rate for communication. Note that the factory-set baud rate is
documented on the Configuration Sheet. If using a fixed ID, verify
that the designated ID is correct for the 39
plus
-IM with which you
want to communicate. Click OK.
B.
In the Communications menu, select
Connect
(if
Connect
is grayed
out, select
Disconnect and reconnect
). SeatermIM will attempt to
connect at the baud specified in Step A, but if unsuccessful will then
cycle through all other available baud rates.
C.
If there is still no communication, check cabling between the
computer, IMM, and 39
plus
-IM, and try to connect again.
D.
If there is still no communication, repeat Step A with a different
comm port and/or different fixed ID, and try to connect again.
Notes:
•
SeatermIM’s baud rate must be the
same as the IMM baud rate. The IMM
baud is factory-set to 9600, but can
be changed by the user.
•
Set to
Use fixed ID
to designate the
appropriate 39
plus
-IM if there are
multiple IM instruments on the IM line.
If desired, use
Automatically get
instrument ID
if there is only one
39
plus
-IM on the IM line. Note that
the ID is stored in the 39
plus
-IM’s
EEPROM and can be changed so
that multiple IM instruments on a
single IM line each have a unique ID.
See the Configuration Sheet for the
factory-set ID.
Set to
Automatically
get ID
when only one
39
plus
-IM is connected.
Computer COM port and baud rate for
communication between computer and SIM
or IMM. SeatermIM tries to connect at this
baud rate, but if unsuccessful will cycle
through all available baud rates.
Set to
Use fixed ID
if
multiple IM instruments
are on-line. Enter ID for
instrument with which you
want to communicate.
Note:
!iiGetHD
and
#iiGetHD
provide factory-
set data such as instrument type, serial
number, and firmware version for the
39
plus
-IM’s integrated IMM and
acquisition microcontroller, respectively.
