Appendix C. HDX2000L Library
The HDX2000L library enables a programmer to create an application that
controls remote Pro Switching System units with minimal effort. It provides basic
functions and alarming such as switching to a specific port or monitoring a
particular signal.
The library controls units connected to an Ethernet 10BASE-T network via
SNMP messages and sits on top of the Windows WinSNMP interface provided with
the library.
