APPENDiX A
DATA TRANSLATION FORMATS
A.1 INTRODUCTION
This appendix defines the data translation formats available
for the 298. The 298 is capable of interfacing with all
RS232C serial equipment employing a data translation
format described in this appendix.
Each data translation format is assigned a 2-digit code
which the operator enters into the programmer (from the
keyboard or, in remote control, through the serial por.t) to
send or receive data in that format. In addition to the data
translation format code, there is a 1-digit instrument
control code which specifies control characters to be
transmitted to, or received from, peripheral instruments.
In several cases, the 298's standard display symbols will be
shortened to accommodate large address fields used with
some translation formats. These are:
• Copy Ram to Port

A.2 DATA VERIFICATION
For data verification the 298 calculates a sum-check of all
data sent to or from the programmer. At the end of a
successful input operation, the programmer will display the
sum-check of all data transferred. It will also compare any
received sum-check fields with its own calculation. If the
two agree, the programmer wiii dispiay the sum-check; a
mismatch will produce an error message. Output data is
always followed by a sum-check field which may be printed
on disk or tape for use in subsequent input operations.

In the HP format,
ZZ:ZZ:ZZ.
represents the six least significant
digits in the 8-digit address field. If either of the two most
significant digits in the field is not zero, the display will show
PORT instead of the address. To view the address, reinitiate the
key sequence for the input or output operation.
