5.2 Saving and Transferring Data
Connecting a personal computer to the Tracer AV EDP
port allows you to save configuration data to the PC or
to download configuration data from the PC to a
Tracer AV . The following sections describe the
procedures for these save and transfer operations.
5.2.1 Saving Tracer AV Data to a Personal Computer
Configuration data can be saved to a personal
computer connected to the EDP port. The PC must be
r u n n i n g a c o m m u n i c a t i o n s p r o g r a m s u c h a s
PROCOMMPLUS
®
. See Section 2.3.3 on page 7 for
information about serial communications wiring and
EDP port pin assignments.
When configuring the Tracer AV , ensure that the
values set for the BAUD and BITS parameters on the
SERIAL menu match the baud rate, bits, and parity
settings configured for the serial port on the PC. Set
the PRNDEST parameter to EDP.
To save all configuration data, place the Tracer AV in
setup mode and send the DUMPALL EDP command.
The
Tracer AV responds by sending all configuration
parameters to the PC as ASCII-formatted text.
5.2.2 Downloading Configuration Data from PC to
Tracer AV
Configuration data saved on a PC or floppy disk can
be downloaded from the PC to a
Tracer AV . This
procedure is useful when a number of Tracer AV s with
similar configurations are set up or when a Tracer AV
is replaced.
To download configuration data, connect the PC to the
EDP port as described in Section 5.2.1. Place the
Tr a c e r AV i n s e t u p m o d e a n d u s e t h e P C
c o m m u n i c a t i o n s s o f t w a r e t o s e n d t h e s a v e d
configuration data to the
Tracer AV . When transfer is
complete, calibrate the Tracer AV as described in
Section 4.0.
NOTES:
• Calibration settings are included in the
configuration data downloaded to the
Tracer
AV . If the receiving Tracer AV is a direct
replacement for another Tracer AV and the
attached scale is not changed, recalibration is
not required.
• When downloading configurations that
include changed serial communications
settings, edit the data file to place the serial
communications changes at the end of the
file. Communication between the PC and
Tracer AV will be lost once the Tracer AV
receives settings for baud rate (BAUD
parameter) or data bits and parity (BITS
parameter) that do not match those configured
for the PC.
