• VME64 extensions / Transition Board
• Full EMC shielding and insertion/extraction handles
• RP0 and RP2 connections
• Routes all signals to/from four IP sites.

Product Description

The TB 8307 is a 6U (double height) VME rear I/O transition board, which provides connection to the
8002 Carrier Board and routes all signals to/from the I/O connectors of the four IP sites. The lower two
groups are directly connected and the upper two connect via plug-in daughter boards which can provide
filtering or isolation.

Construction

The unit is constructed to the VME64x standard, with EMC rear panel, injector/ejector handles, guide
pin and slot keying, static discharge protection, hot swap capability, 5-row RP0 and RP2 connectors.

Features

1	Straight-through connections for 8002 carrier board sites A and B
2	Signal conditioning in-line with connections to sites C and D by means of plug-in signal
	conditioning board (SCBs)
3	Four 50-way front panel SCSI connectors. 
4	Various SCB options (opto-coupled digital or filtered analogue)
5	On-board DC-DC converter options supply SCBs and external sources.
6	Signals routed as pairs.

Specification

Mechanical:		Standard 6U high VME64X transition board
Operating temp:		0 to 45 deg C ambient
Number of signals:		4 x 50 (2 groups direct, 2 groups conditioned)
SCB Isolation:		100V with respect to VME GND
Power (fused at 3A):	+5V @ 2A typical for 2 off DC-DC converters
Electrostatic discharge:	via 2M2 to chassis ground and VME GND

Operating Modes

Configuration
Front panel connectors 1 and 2 are routed straight-through to carrier board IP sites A and B.
Front panel connectors 3 and 4 are routed to the 50-way I/O connectors of SCB sites C and D.
The opposite sides of the SCB sites each have another 50-way connector which are then routed
to carrier board sites C and D via VME backplane connectors P0 and P2.
Thus the SCBs form a bridge between each front panel connector and its associated carrier IP site.

The SCB cards which are available are:-
9202		Analogue signal conditioning board
9301		Isolated x16 Digital Input SCB
9303		Isolated x16 Digital Output SCB
9304		Straight-through SCB
9305		Isolated x8 Digital Input, x8 Digital Output SCB

Links
Links allow the isolated analogue grounds of each SCB group to be connected to digital (VME) ground.
LK1- SCB site C
LK2- SCB site D

Excitation
Two DC-DC converter sites are available for SDC9912 DC-DC Converter cards to power SCB sites C 
and D with isolated +/-12V DC via a 6-way power connector

Front Panel SCSI Connectors 
Connectors 1 and 2 are routed directly to carrier board sites A,B
Connectors 3 and 4 are routed via SCB sites C and D to carrier sites C and D
