Installing the VRPD 2
2.5 Edge Connector Terminals and Pin Assignments
The edge connector is a 64-pin, Type G (DIN 41612).
The pin assignments for the edge connector are not fully downward compatible with
older amplifier products.
Differences in pin assignments have been implemented such that damage is prevent-
ed if an old controller card (VT 12350-3x or VT 12352-3x) is replaced by a VRPD
controller card.
