5.2 Saving and Transferring Data
Connecting a personal computer to the 120 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 2.2.1 on page 5 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 PRNDES
parameter to EDP.
To save all configuration data, place the indicator in configuration mode and send the DUMPALL EDP
command to the indicator. The 120 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 indicator
in configuration mode and use the PC communications software to send the saved configuration data to the
indicator. When transfer is complete, calibrate the indicator as described in Section 4.0 on page 21.
Note
• Calibration settings are included in the configuration data downloaded to the indicator. If the receiving
indicator is a direct replacement for another 120 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.
