Reads the firmware version of the Remote Module:
Command:
4<CR>
Response:
Geokon405 Ver1.0 0320
Example 2: REQUEST 6 READS:
Get sensor readings for up to six Vibrating Wire "cells"
("0000000" returned for unconnected gages):
Command:
V6<CR>
Response:
0200000 0000000 0000000 0000000 0000000 0000000
Notes:
• The above response shows that there is one gage (of six) connected
• Raw gage values are in units of nanoseconds
• Frequency (F, in Hz) = 1 / T (sec); F = 1 / 0.0002 = 5000 Hz
• Digits = F2/1000 = (5000)2/1000 = 25000
