Remember!

If any of the piggybacks you wish to use need any of the signals shown

bold/italic above (i.e. a 5230-xx type), a VMOD-2 set for an 8 KByte wide

address area must be used. Any piggyback not needing these additional

lines can be used on the VMOD-2 in either a 256 Byte or 8 KByte address

width setting.

2.5.2VMOD-2 External Interface Connectors BU2a and BU2b

The twenty-six pin double row sockets are totally isolated from the remaining circuits of the

VMOD-2, and only connect the input/output side of the respective piggybacks 26-pin I/O

header directly to the upper or lower half of the 50-way VMOD-2 front panel connector.

The actual pins used are subject to the design of the piggyback, but the pin interconnections

between the two BU2 connectors and the 50-way front panel connector will always be the

same. To determine what pin-s your signals will appear on when using any ready made piggy-

back, please see the piggyback's user manual which will give precise details of the external

interfaces for use in both locations. If fault-tracing or designing your own piggybacks, the rela-

tionship of the respective piggyback locations (inputs/outputs) to the external connector is as

given in the table below.
