8900NET Instruction Manual 63

Functional Description

ROM and RAM

Software updates can be made to the 8900NET ROM through the Web-

based interface. Non-volatile RAM is provided to store key setup values

when power is cycled.

Ethernet Port

The 10Base-T Ethernet port provides conﬁguration and monitoring access

to the frame, frame modules and the 8900NET module using a Web

browser.

RS-232 Serial Port

The RS-232 port is used to initialize the module with critical network

parameters including a static assigned IP Address. Ethernet MAC address

is stored on a serial EPROM on the frame. (The frame needs both MAC and

IP Addresses.)

Module Health Bus

The Module Health bus connects all the audio/video module cells to the

microprocessor. It is used to report module faults or data errors.

Frame Bus

The Frame Bus provides serial communication to each of the audio/video

modules for remote conﬁguration and monitoring over a network.

Module Present Detection

Module Present lines from cells 1 through 10 and Present/Health lines

from cells 12 and 13 are monitored by the microprocessor using the Module

Present Detection circuitry. For cells 1 through 10, this circuit reports to the

processor whether a module is present and if it supports frame bus com-

munications (control and monitoring). For cells 12 and 13, this circuit

reports if the power supply is present and if it is working properly.
