complete.
1.0 Introduction
The 920i is a programmable, multi-channel digital
weight indicator/controller. The conÞguration can be
performed using the front panel, with an attached
PS/2
¨ 1 -type keyboard, or using the iRev utility.
Custom event-driven programs can be written with the
iRite language up to 128K in program size. These
programs are compiled with an iRev compiler utility,
which can only be downloaded into the indicator. The
RLWS Web Update utility can be used to download
920i Þrmware upgrades to a PC from the RLWS web
site; iRev provides functions for installing the new
software into the 920i .

inputÑeither from A/D cards or serial input
from an external digital indicator. The maximum
number of scale inputs is 28; these can be
c o m b i n e d t o r e p r e s e n t u p t o 3 2 s c a l e
conÞgurations.
