Page 5-6 Sending and Receiving Information
Transmitting Information to Another Device
Once you have established communication, you can set the FieldBook up to transmit
information to the other device. The FieldBook has three Transmit Modes:
Mode 2-1, Transmit Serial Data: Sends data from a data file
Mode 2-2, Transmit Serial File: Sends an entire format, data, or program file, including
filename and type
Mode 2-3, Transmit Serial Memory: Sends an image of the entire FieldBook memory in
hexadecimal form
In addition to using the Transmit Modes, you can transmit data using a Polycode program.
▲ ▲ ▲ ▲ ▲ Transmission Communication Parameters
Before you can transmit information from the FieldBook to another device, you need to set
up the transmission communication parameters on the FieldBook. This is done in Mode 5-2,
Set Communication Protocol. Refer to Section 3, Operating System, Operating Modes, Mode 5:
Set, for details on how to use Mode 5-2. A description of the parameters follows.
Line Request Character
The FieldBook interprets the line request character when received from the keyboard or the
RS-232C port as the signal to send one line of data. Any single ASCII character can be used.
The device sends the line request character, then reads and stores the line of data sent in
response by the FieldBook. The default character is A.
Repeat Request Character
The FieldBook inteprets the repeat request character when received from the keyboard or
the RS-232C port as the signal to retransmit whatever line was last transmitted. This param-
eter is useful if the FieldBook transmits over phone lines to a computer that can detect
transmission errors. Any single ASCII character can be used. The default character is B.
Continuous Request Character
The FieldBook interprets the continuous request character when received from the keyboard
or the RS-232C port as the signal to transmit data continuously until either the end-of-file is
reached or until it receives another valid request character. This is the request character most
often used. If you are sending data to a computer, use the continuous request only if you are
controlling data flow with the RS-232C handshaking lines. Any single ASCII character can
be used. The default character is C.
Stop Request Character
The FieldBook recognizes the stop request character as the signal to stop transmission at the
end of the current line. Any single ASCII character can be used. The default character is D.
