4.5 Connection for the Master/slave function
This operation must be carried out solely by authorized personnel.
Before beginning any operations ensure that the electricity
supply of the distributor has been disconnected.
TRIPLE POWER BOARD CONFIGURATION
All VISTA dispensing machines are configured with the jumper only on pin 1
of input connector A. For triple configuration, and hence as B, position the
jumper on pins 1 and 2 of input connector B.
To combine a VISTA vending machine with a BVM921, they need to be
configured as A, otherwise the master machine will not recognised the
connected slave.
