5.1.6 Normal Mode Commands
The serial transmit weight data commands (see Table 5-2 on page 28 ) transmit data to the EDP port on demand. The SX and
EX commands are valid only in normal operating mode; all other commands are valid in either setup or normal mode.
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 running a
communications program such as PROCOMMPLUS ® . See Section 2.3.3 on page 10 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 AVs 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 Tracer AV in setup
mode and use the PC communications software to send the saved configuration data to the
Tracer AV
. When transfer is
complete, calibrate the Tracer AV as described in Section 4.0 on page 24 .
• 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.
