Upon power on the counter module defaults to the following setup:

Baud rate: 9600 baud, 8 data bits, no parity, 1 stop bit

Cycle rate: 10 Hz

Analog channels: Channel 0 (Larmor signal level) enabled, channels 1-5 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. Table 5 illustrates an example of this
format.

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
99999.999nT).
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
If the data were captured to a file and then copied to a line printer the printout would look
