Option 19 allows up to nine (9) Print Master 710C, 710E or 710F models to be cascaded allowing you to increase the number of available ports. All 710 models with Option 19 may be cascaded together. The primary difference in 710 models with Option 19 versus standard 710 models is the incorporation of a Unit ID Number. The unit ID number is used to direct a print job to a specific 710 model in a cascaded chain of units and is very similar to the printer assignment number described in Section 6.2.2. Ports 9 and 10 of each unit are reserved as cascading ports. Port 9 or Port 10 may be used as computer ports (if the port is available), but have the following limitations:
1.XON/XOFF is not available on these ports.
2.The Header Page Message is not generated on these ports.
3On the Print Master 710C only, Ports 9 and 10 will always default to the same configuration.
4.Under certain conditions, a Printer Select Code is generated at Port 9 or Port 10 and will be passed to a computer if it is connected to the port.
5.Ports 9 and 10 do not feature a minimum
The steps to installing and operating 710 models with Option 19 involve configuring each unit (see Appendix B.1), cabling the units together (see Appendix B.2), and operation (see Appendix B.3).
