You may plug the transformer intothe 120VAC outlet, but do not plug in the transformer for the printer at this time. Plugthat transformer in when the installation of the system is complete.Addressing the Printer Interface UnitThe printer interface unit(s) use communication group number 02 on the RS-485 bus, and unitnumbers 0 (master printer) and 7 (slave printers).
