5.2 Saving and Transferring Data
Connecting a personal computer to the 420HE 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 2.3.3 on page 8 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
420HE 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 in dicator. 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.
NOTES:
• Calibration settings are included in the
configuration data downloaded to the indicator.
I f t h e r e c e i v i n g i n d i c a t o r i s a d i r e c t
replacement for another
420HE 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.
