1.0 Introduction
The 720i is a single-channel, programmable digital
weight indicator/controller. The configuration can be
performed using the front panel, with an attached

-type keyboard, or using the Revolution III
utility.
The 720i can be loaded with either PCE software or
720i batching software. Refer to Section 8.0 on page 65
or Section 9.0 on page 81 for further information on
each of these software choices.
Onboard Features
Features of the basic 720i include:
• Support for a single A/D or serial scale input.
• Eight digital I/O channels on main board, each
configurable as either input or output.
• Two serial ports on main board support duplex
RS-232 up to 115200 bps. Port 2 supports RS-232
with hardware handshaking; Port 4 supports
RS-232 and 20mA communications.
• Available in 115 VAC and 230 VAC North
American and European versions.
• Configurable print formats can be defined for up to
1000 characters each using serial commands or
Revolution III . These formats are used to print
gross or net weights, truck in/out weights,
accumulator weights, alert messages, and header
information. Additional print formats can be
created using twenty auxiliary print formats.
• Seven truck modes to store and recall weights for
gross, tare, and net printing. The truck register
contains fields for ID number, weight, and the
transaction time and date. Weights can be stored
permanently or erased at the end of the transaction.
