Balance Input Driver Specifi cations
Overview
The 6750 Proximate Interface supports input
from the three balance types indicated below. Ad-
ditionally, a generic input driver is provided for
communications with balances that do not conform
to the directly supported protocols. A feature sup-
ported by all balance input drivers is the ability to
change the expected number of characters in the
data fi eld. The number of data characters indicated
for each of the drivers, below, are default values.
This feature virtually eliminates the need for balance
input drivers to be re-written in the event the bal-
ance manufacturer elects to alter the output string
of a balance when new models are introduced.
The format of an unknown balance can be deter-
mined by logging the balance output to display. In
order for the logging to produce meaningful results,
the cable connecting the balance to the balance
input port of the Interface must be correctly wired
or confi gured. In addition, the specifi cs of the data
frame, such as the baud rate, # of data bits, parity, #
of stop bits and handshaking (if used) must be the
same for both the balance and the Interface.

The ID fi eld must contain “S_” to indicate a
stable mass. The data fi eld contains the current
mass, right justifi ed, with a decimal point. The bal-
ance should be confi gured to send continuously.

The ID fi eld must contain “S_” to indicate a sta-
ble mass. The data fi eld contains the current mass,
right justifi ed, with a decimal point. The balance
should be confi gured to transmit data upon receipt
of the following command string:
S [CR] [LF]
Note: The automatic data output option should not
be used.
The interface will send this command string
once after the PROCEED key has been pressed
during a mass entry sequence. The PROCEED key
should only be pressed when the mass reading is
stable. However, unstable readings will be rejected
and a warning will be issued. Acknowledging the
warning by pressing the CLEAR ENTRY key will re-
start the mass entry process all over again.
