REMOTE LINE SELECTOR MODULE — LOGIC I/O
The 24-pin LOGIC I/O connector allows the RLS
module to control, or to be controlled by, the device
connected to the module. A device can connect di-
rectly to the module, but more commonly input se-
lection would be done through a switcher. Two types
of switchers are supported: VistaMax (or other rout-
ers) and the PRE99-947 External Remote Line Se-
lector (Ext. RLS).
The source type (switcher or direct) and the
switcher type (VistaMax or Ext. RLS) are set via
the module’s SETUP DIP switches (see page 2-29).
When the module connects to an Ext. RLS, sev-
eral logic connections (pins 15, 16, 17 and 23) be-
come RLS address outputs. This change occurs only
when DS2-4 is set ON and DS2-5 is set to OFF.
When a VistaMax or other router is used (DS2-5 is
set ON), these pins do not change function since
addressing is done through the Session module.
