The ER-A750 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.
