3.15 Extended Read/Write AutoScan Command
When the Module Mode =1 (initiate), the H-4161 actively initiates measurements and collects the
response from the sensor attached to the auxSDI port. These two commands allow the user to
select which “M” command is sent by the H-4161 when it initiates a measurement ( “0M!”,
“0M1!”, “0M2!" etc.) . The H-4161 comes from the factory with this setting set to “0" (“0M!”).
Only the settings “0" to “9" are valid:
0 = 0M! (default)
1 = 0M1!
2 = 0M2!
3 = 0M3!
4 = 0M4!
5 = 0M5!
6 = 0M6!
7 = 0M7!
8 = 0M8!
9 = 0M9!
This setting stored in non-volatile Flash memory. Once a new value is written to the Flash
memory, a copy is sent to the sensor data buffer for verification. This setting can be viewed by
using a subsequent "D" command. To verify this setting any other time, use the "XRAC"
command. This command takes 1 second to complete and places 1 value in the data buffer.
