6 EDP REMOTE COMMANDS AND SERIAL PORT OPERATION

Besides sending serial communications to remote peripheral devices, the IQ plus 310A can
also process incoming serial communication commands from a remote keyboard through
its EDP (Electronic Data Processing) port. Incoming commands can be used for three
purposes:
• Setup and configuration
• Calibration
• Normal weighing operations
Some commands are accepted in the SETUP as well as the OPERATE mode. Commands
are NOT accepted during a printing operation, or when calibration is being performed.
The EDP command format is as follows:
Where: COMMAND = a 2-letter command (upper or lower case letters)
n = a selection code or numerical entry
CR = a carriage return
By eliminating the selection code or numerical entry, the command becomes an inquiry.
The IQ plus 310A responds with an "OK" if the command string is valid.
The IQ plus 310A responds with the value of the parameter if the command is an inquiry.
The IQ plus 310A responds with "??" If the command string is invalid, or if trying to change
a setup value while in OPERATE mode.

6.1 EDP SETUP COMMANDS

The setup parameter commands use a single-digit selection code for most functions.
Grads, Ticket Format, and Calibration require numerical entries. See the Setup Menu
Descriptions in Section 3.3 for code identification. All Setup commands listed in the chart can
only be used when the indicator is in SETUP Mode.

6.2 EDP CALIBRATION COMMANDS

The Calibration commands are valid only when the indicator is in the SETUP Mode. While
calibration is in progress, the indicator displays "CALIB". The indicator returns "OK" when
calibration is completed.
COMMAND DESCRIPTION OF FUNCTION
CD Calibration of Deadload or Initial load (Zero)
CW Calibration of Test Weight. If the test weight is not equal to full scale
capacity, send the EDP command CW "nnnnnnn" <CR>, where
nnnnnnn is the numerical value of the test weight. See Section 4.1.
Serial input and keyboard commands are ignored until the calibration
is completed.
CZ Re-zero. See Section 4.2.
