Audio
This allows you to set several parameters relating to the volumes and frequencies of the various
audible tones. See below for more details.
Date & Time
Selecting this will allow you to set the date and time. See below for more details.
Com Port Setup
Selecting this will allow you to set the functions and baud rates of COM1 through COM4. This
sets the baud rate of the serial for both incoming and outgoing data. Rates are selectable from 1200 to
115200. The system default is 9600. See below for more details.
Com & Field Note Setup
This allows you to define ASCII text strings to be either sent out the serial port or stored as field
notes. Sending strings out the serial port is useful for controlling a GPS system. Field notes are useful to
mark any desired event.
Each string is associated with a particular key press. During a survey, pressing the key
will cause the associated string to be either stored as a field note, or sent out the RS-232 port as a
command. See below for more details.
Magnetometer Test
This selection opens a screen that provides information about the state of operation of the
Magnetometer. Also presented are a selection of internal volatages that indicate the state of the system.
See below for more details.
Real Time Transfer
Enabling real time transfer will cause data to be sent out the serial port during the acquisition. The
data coming out will be formatted exactly as for the ASCII data transfer. The setting will not affect
whether or not data is stored inside the G-858BP. The options here are 'DISABLE' and 'ENABLE'. When
EM-61 data is being acquired this should be set to 'DISABLE'. Sending data in real time to the EM-61
causes the EM-61 to report a huge[*] number of errors.
[*] huge = large enough to cause trouble. The G859 gets
bogged down processing these error messages.
