module QuerIeS and commandS
Communication with the module requires you to specifically identify the module location. As shown below, this is done by appending a 1, 2, or 3 to the end
of the query.
Queries
X Firmware Version
MOD:VER? 1 ... Returns the nVision firmware version of the lower module in the RXXXXXX.XX format.
MOD:VER? 2 ... Returns the nVision firmware version of the upper module in the RXXXXXX.XX format.
MOD:VER? 3 ... Returns the nVision firmware version of the BARO module in the RXXXXXX.XX format.
X Full Scale range
MOD:FR?
Note: This query is not applicable to the RTD100 module. Full scale range for MA20 switch test is “1". Full scale range for BARO is “15".
XXXX = 0 disables Automatic Shutoff (always on)
XXXX = seconds:
30 45 60 120 180 240
seconds seconds (1 min) (2 min) (3 min) (4 min)
300 600 900 1200 1800 2700 3600
(5 min) (10 min) (15 min) (20 min) (30 min) (45 min) (1 hr)
These values can be set to anything from 1 to 3600 seconds. However, once connected to CrystalControl
this value will be reset to the closest value shown in the table. For example, sending the command AO!75
instructs the nVision to set the Automatic Shutoff time to 1 minute.
