HARDWARE
Host Controller (HC-12)
Overview
The host controller provides the centralized intelligence for the IP-12/IP-16
control surface. The HC-12 communicates to the Console Blade via TCP/IP over
Ethernet through a standard ethernet hub or switch.
Hardware and software conguration, as well as real time crosspoint information,
is saved in non-volatile storage on the HC-12 card and is restored at power up or
reset. This conguration information provides details to the host application running
on the HC-12, such as the specic audio hardware available.
Ethernet IP Addressing
The Wheatstone IP-12/IP-16 control surface ships with the host controller IP
address set to 192.168.87.201. Stand-alone systems (not interfaced to a station’s
existing network) require no IP address changes.
Ethernet Interface Wiring
Networked systems are connected to the network hub or switch via a straight (pin
to pin) CAT5 cable. Typical CAT5 cable pinouts are included in the “Hook-Ups”
section later in this chapter. This connection is for communicating with the Console
Blade, any other Blades or controllers in the system, and the conguration computer.
