Serial Communication Port
The FieldBook has a D type serial communication port with 25 pin contacts. The port is
sealed against moisture and fitted with a soft plastic plug to protect the pins. A slide lock
secures connectors when they are attached to the port.
The communication port handles the following:
❏ Serial RS-232C Communication Signals
The RS-232C serial port is used for transferring data between the FieldBook and a
computer, modem, printer, or another FieldBook. It can also read data from measurement
instruments which output information in RS-232C serial signals, such as bar code wands
and scanners, electronic balances, and water quality sensors.
❏ External Wakeup
The ring indicator can wake the FieldBook up from a powered-down state to collect data
based on an external event.
❏ Battery Charging
The main FieldBook batteries are charged through an AC battery charger which is
connected to the communication port.
❏ Digital Inputs and Outputs
The digital inputs can read data from digital sensors such as the Water Content
Reflectometer which measures the water content of porous media. The digital outputs can
be used in control applications to open switches for activating alarms or other devices.
❏ Clocked Serial Data Communications
Data can be read from sensors with a clocked serial output such as the Mitutoyo
Digimatic Caliper.
The connector pinouts are shown in Section 8, Technical Reference, Serial Communication Port
Connector Pinouts.
