Geometrics Inc. G-882 Cesium Marine Magnetometer Page
Upon power on the counter module defaults to its last saved setup as defined by
the user using the UPDATE function described later.
Baud rate: 9600 baud, 8 data bits, no parity, 1 stop bit
Cycle rate: 10 Hertz
Analog channels: Channel 0 (Larmor signal level) enabled, depth and altitude
Channels, when applicable, enabled, and channels 3-8 disabled.
Julian Clock: Disabled
Output Format: ASCII
The default output data stream contains all printable ASCII characters with each
sample terminated with a carriage return/ line feed sequence. The following
example illustrates this format where there are no depth or altitude analog
channels enabled:
char # description
------- ----------------------------------
1 An ASCII '$' (marks first character of data stream)
2 an ASCII '1' or a blank (depending on whether Mag reading is above or
below _99999.999 nT).
3-7 5 digits of Mag data
8 an ASCII decimal point ['.']
9-11 3 more digits of Mag data
12 an ASCII comma [',']
13-16 4 digits of A/D channel 0 (9999 full scale, 0 to +5 volts in). This channel
is internal
and contains the signal level of the magnetometer.
17 an ASCII carriage return
18 an ASCII line feed
