Guide to Transmitting Serial Files
❏ To initiate transmission, send a request character from the connected device or key it in
on the FieldBook's keyboard.
❏ Checksums, if enabled, follow each line in the body of a data file.
❏ An end-of-line sequence follows every output line. This is typically a carriage return
followed by a line feed.
❏ One blank is output between the data and the checksum, but it is not counted when
calculating the checksum
❏ An & is sent at the end of each file.
Mode 2-3 Transmit Serial Memory
The Transmit Serial Memory submode is used to transmit an image of the entire FieldBook
memory in hexadecimal form through the RS-232C port to a computer or another FieldBook
for reloading at a later time. Instructions for using Mode 2-3 follow.

Guide to Transmitting Serial Memory
❏ To initiate transmission, send a request character from the connected device or key it in
on the FieldBook's keyboard.
❏ The first line of the output file contains the total number of bytes being saved, expressed
as a four-digit hexadecimal number.
❏ The final line is a four-digit hexadecimal checksum.
❏ The body of the memory image transmitted between the two checksums should be a block
of 64 character lines of hexadecimal numbers. If the lines are longer or shorter than 64
characters, the memory image has not transmitted correctly to the connected device.
