5.2 Saving and Transferring Data
Connecting a personal computer to the
420 Plus
EDP
port allows you to save indicator configuration data to
the PC or to download configuration data from the PC
to an indicator. The following sections describe the
procedures for these save and transfer operations.
5.2.1 Saving Indicator Data to a Personal Computer
Configuration data can be saved to a personal computer
connected to the EDP port. The PC must be running a
communications program such as PROCOMMPLUS
® .
See Section 2.3.5 on page 10 for information about
serial communications wiring and EDP port pin
assignments.
When configuring the indicator, 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 indicator in
setup mode and send the DUMPALL EDP command to
the indicator. The
420 Plus
responds by sending all
configuration parameters to the PC as ASCII-formatted
text.
5.2.2 Downloading Configuration Data from PC to
Indicator
Configuration data saved on a PC or floppy disk can be
downloaded from the PC to an indicator. This
procedure is useful when a number of indicators with
similar configurations are set up or when an indicator is
replaced.
To download configuration data, connect the PC to the
EDP port as described in Section 5.2.1. Place the
i n d i c a t o r 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 indicator. When transfer is
complete, calibrate the indicator as described in
Section 4.0.
Note
Calibration settings are included in the
configuration data downloaded to the indicator.
If the receiving indicator is a direct
replacement for another 420 Plus 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 indicator will be lost
once the indicator receives settings for baud rate (BAUD
parameter) or data bits and parity (BITS parameter) that do
not match those configured for the PC.
