Additional information about the Dominion SX16 and SX32 Terminal
Ports:
 Pins 1 and 9 are used to factory reset units shipped after August
2004.
 Units shipped prior to August 2004 have the DB9M port labeled
RESERVED (not TERMINAL/RESERVED), since this port was used
to factory reset the unit, with a Factory reset adapter shipped with
each SX unit. Pins 1 and 6 were used for factory reset. The reset
adapters for these early units are different from the current units,
which have local port functionality.
 DSX16 and DSX32 units shipped from the factory with the SX2.2 (or
higher) release support the local port capability.
 DSX versions through 2.5 have the local port disabled by factory
default.
 In DSX 3.1 or higher, the local port is enabled by default.
