7.5 External Panel Cabling (Optional)
SAM external panels can be connected to the router by using RS485 cables and the
Multidrop Communications protocol (SW-P-06).
The Sirius 830 is supplied with a default database. The default database configures the
RS485 3 (COM 5) connector on the rear of the router to use the Multidrop Communications
protocol (SW-P-06). RS485 3 (COM 5) supports a variety of BPX and XY control panels (see
Table 8. on page 50 for details).
Fig 17. shows the RS485 connector pin-outs for Multi-drop cables. See section 7.5.2 for
details on connecting an external panel to the router and section 10.6 for operating the
panels.
