An RS-232C communication cable is used to connect the FieldBook to a computer, printer, or
another FieldBook. Two models are available from Juniper Systems:
- CA-009-9: features one 25 pin D subminiature connector with socket contacts to plug into
the FieldBook's serial port and one 9 pin D subminiature connector with socket contacts to
plug into devices with a 9 pin communication port.
- CA-009: features two 25 pin D subminiature connectors with socket contacts. One
connector plugs into the FieldBook's serial port and the other plugs into devices with a 25
pin communication port.
The cable length for both models is six feet.
