Setting Up Communication With Another Device
You can transmit data and files directly from the FieldBook
to another device, including a computer, printer, terminal,
or another FieldBook using the Transmit Modes. You
can also load information from another device to
the FieldBook using the Load Modes. The Transmit
Modes and Load Modes complement each other
exactly.
To get the FieldBook to communicate with another device, you must complete these tasks:
- Make the appropriate hardware connections with an RS-232C cable.
- Set up the communication protocol parameters on the FieldBook and the other device so
that a communication link can be established. If you are communicating with a computer,
you can use the PolyTools transfer option, the Windows Terminal program, or any
commercially available communication program.
▲ ▲ ▲ ▲ ▲ Hardware Connections
To connect the devices together, you must have a properly wired RS-232C communication
cable. The appropriate cable is available as an optional accessory from Juniper Systems. A
schematic of this cable can be found in the Appendix.
To connect the devices, plug the FieldBook end of the connector into the RS-232C
communication port on the top of the FieldBook and the other end into the communication
port on the other device.
▲ ▲ ▲ ▲ ▲ Communication Protocol Parameters
The next step is to ensure that the sending and receiving devices speak the same language.
The values for baud rate, data bits, parity, and stop bits on the FieldBook and the other
device must match to establish the communication link. You can change these parameters to
match the settings on the other device or vice versa. The duplex and communication port
settings do not have to match. A description of these parameters follows.
Baud Rate
The FieldBook will send or receive at rates of 300, 600, 1200, 2400, 4800, 9600, and 19200 bits
per second. The default is 9600.
Data Bits
The FieldBook can send or receive either 7 or 8 bit characters. The default setting is 8.
Stop Bits
The FieldBook can send or receive either 1 or 2 stop bits. The default setting is 1.
