Host Controller (HC-3)
Overview
The host controller card used in the E-1 incorporates a PC/104 computer mounted
on the HC-3 PCB. The host computer utilizes RAM, a flash disk (which emulates
a standard IDE hard drive), and an Ethernet port. There is no hard disk drive. A
video port is provided for the user-provided VGA monitor, and a keyboard port is
for factory use only.
The purpose of the host controller is to provide control of the E-1 control
surface. The HC-3 communicates to the Navigator Configuration PC via
TCP/IP over Ethernet through a standard ethernet hub or switch. It also communicates
to the Network Router via a special mixer link connection when used in a TDM
system. This connection is not used with a WheatNet-IP system.
Hardware and software configuration, as well as real time crosspoint information,
is saved in non-volatile storage on the HC-3 card and is restored at power up or reset.
This configuration information provides details to the host application running on
the HC-3, such as the specific audio hardware available.
HC-3 BIOS Settings/Format
BIOS Setup and formatting of the Host CPU is completed prior to the testing
of your E-1 control surface at the Wheatstone factory. There are no user adjustable
settings.
Ethernet IP Addressing
The Wheatstone E-1 control surface ships with the host controller IP address
set. 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 near the end of this chapter
.
These connections are for communicating with
the configuration computer; a separate ethernet connection should be provided for
each control surface.
