A-5
SB
Initialize modem
Param 1 (String): A command string used to initialize the modem. All
parameters must be entered on one line with no spaces. The command
string is sent to the modem at startup.
Example — Sets the modem to auto-answer after two rings and disables
DTR line checking:
ATS0=2;&D0&K0
SC
Coordinate Flash/BBRAM totalizers
Param 1 (0 or1): Direction of coordination:
If 0, then the Flash totalizers are set to the current value of the BBRAM
totalizers. If 1, the BBRAM totalizers are set to the current value of the Flash
totalizer.
SD
Set all settings to system defaults
NOTE: Reset the unit to factory defaults by entering an SD command fol-
lowed by an SS command.
SF
Control/Programming port flow control
toggle
Param 1 (1 or 0): Toggles flow control on the unit’s programming port. Flow
control (CTS/RTS) can be used if the unit is connected to a modem or other
telephony device. 1 enabled flow control, 0 disabled flow control.
SH
Reinitialize hardware to current settings
This command configures all hardware for the current settings without a
restart.
SI
Instrument type
Param 1 (Range 1 to 3): The instrument connection that is being set. This
corresponds to the connections labeled 1 to 3 on the front panel.
Param 2: The instrument type. The valid entries are “ADFM,” “AccQmin,”
“HADFM,” and “NONE.” If the instrument type is “None” then the given port
is disabled.
Example —
Sets instrument 1 as an ADFM.
?>SI 1 ADFM
SM
Modem Connected
Param 1 (Range 1 or 0): 1 if a modem is connected, 0 if it is not. If 1, the
modem initialization string will be sent at startup (see SB command); this
does not turn flow control on or off (see SF command).
SN
Site Name/Instrument Name
Param 1 (Range 0 to 3): The device for which the name is being set. 0 is the
site device name, 1 – 3 are the instrument names.
Param 2: The site name length. Must be less than 12 characters, alphanu-
meric only.
SO
Instrument time-out
Param 1 (Range 60 to 3600+): The time-out for instrument 1 in seconds. If
the specified time elapses without a valid reading from the instrument, then
the bad data counter is incremented. If this counter reaches the value spec-
ified by the AB command, the analog output returns to 4.0 mA. The mini-
mum value is 60 seconds; if the value is greater than 3600, the time-out
counter is not used.
Param 2 (Range 60 to 3600+): The time-out for instrument 2 in seconds
(see parameter 1).
Param 3 (Range 60 to 3600+): The time-out for instrument 2 in seconds
(see parameter 1).
NOTE: To disable time-outs, enter a value greater than 3600.
