Remote SIM Commands
SIM commands are directed to the remote Surface Inductive Modem, to set it
up for operation with the 39
plus
-IM.
Power-On
Commands
PwrOn
Send wakeup tone to
all
IM instruments
on-line.
PwrOff
Send power-off command to
all
IM
instruments on-line. Main power turned
off and IM instruments placed in quiescent
(sleep) state. Data logging and memory
retention not affected.
Status
Command
DS
Display SIM status.
Communications
Commands
Baud=x
x
= baud rate between SIM and computer /
controller (1200, 2400, 4800, or 9600).
Default 9600.
DataNNMax=x
x=
timeout (0-32767 millisec; SIM rounds
down to nearest 50 millisec) that applies to
!iiData
and
Dataii
only. If no reply
received within
DataNNMax
, control
returned to computer and other commands
can be sent.
Default 1000 millisec.
RelayMax=x
x=
timeout (0-3276 sec) that applies to all
commands other than
Dataii
or
!iiData
. If
no reply received within
RelayMax
,
control returned to computer and other
commands can be sent.
Default 20 sec.
EchoOn
Echo characters received from computer
(default) - computer monitor will show
entered commands as you type.
EchoOff
Do not echo characters received from
computer - computer monitor will not
show entered commands as you type.
AutoPwrOn=x
x=Y
: Automatically send
PwrOn
when
power applied to SIM, waking all IM
instruments on-line.
Default.
x=N
: Do not automatically send
PwrOn
when power applied to SIM.
Example:
(user input in bold, command used to modify parameter in parentheses)
ds
SBE 37 SURFACE MODEM V 3.0
wait time for dataNN response = 1000 msec
[
DataNNMax=
]
wait time for relay command response = 20 seconds
[
RelayMax=
]
binary relay character timeout = 1000 msec
[not applicable]
echo = yes
[
EchoOn
or
EchoOff
]
execute pwron command on powerup = yes
[
AutoPwrOn=
]
Note:
AutoPwrOn=N
is typically used
only with a
Tone Detect
board
system for an SBE 44 Underwater
Inductive Modem.
Note:
The status display shows
37
because
the SIM was originally developed for
the SBE 37-IM MicroCAT.
Notes:
•
The SIM’s baud rate (set with
Baud=
) must be the same as
SeatermIM’s baud rate (set in
Configure
in the Communications
menu). After you send
Baud=
, you
must disconnect and reconnect (in
the Communications menu, select
Disconnect and reconnect
) to
communicate at the new baud rate.
•
If outputting data in XML format
(
#iiOutputFormat=2
), Sea-Bird
recommends setting
DataNNMax=
to 4000 millisec.
