2.0 MECHANICAL/ELECTRICAL

DESCRIPTION

This section describes the mechanical and electrical characteristics of

the AutoMax RĆNet Processor module.

2.1

Mechanical Description

The AutoMax RĆNet Processor module is a printed circuit assembly

that plugs into the backplane of the AutoMax/DCS5000 rack. The

module consists of the printed circuit board, faceplate, and protective

enclosure. On the back of the module are two edge connectors that

attach to the system backplane. The faceplate contains ejector tabs

at the top and bottom to simplify removing the module from the rack.

See figure 2.1 for the module faceplate.
The BNC connector on the faceplate provides the means to connect

the module to the RĆNet network. The two rotary switches select the

AutoMax RĆNet module node number in hexadecimal. The upper

switch represents the most significant digit and the lower switch

represents the least significant digit of the node number value. Eight

LEDs on the faceplate indicate the status of the AutoMax RĆNet

Processor module and the RĆNet network. The LEDs are defined as

follows:

READY

(yellow)

When lit, indicates the CPU is working properly
within the limits of its internal diagnostics and the
internal watchdog is being reset.

XMIT

(yellow)

When lit, indicates the module is transmitting via
the coax.

RECV

(yellow)

When lit, indicates the module is receiving via the
coax.

COM OK

(yellow)

When lit, indicates the module's transmit and
receive circuits have passed powerĆup diagnostics.

1st COM ER (red)

When lit, indicates fault code 8 or CRC error.

2nd COM ER (red)

When lit, indicates fault code 4.

3rd COM ER (red)

When lit, indicates fault code 2.

4th COM ER (red)

When lit, indicates fault code 1 or lost token
timeout.

Fault code numbers are valid during powerĆup diagnostics or if the

Ready LED turns off. The condition causing the fault can be

determined by adding the fault codes.
