Introduction
The ER-A770 inter-register communication (IRC) system consists of one master machine and
up to 15 satellite machines/remote printers (max. 9 remote printers) which are all interconnected
by the Sharp Retail Network (SRN) to provide data transmission among them. This system
allows the manager to exercise centralized control over the satellites through the master.
• One of the satellites may be used as a back-up master.
