Note: The stop function is not incorporated in the BK720 and therefore DIP switch S1-2 has to be
set to Disable when a BK720 is used as a feeder.
2.4 Downstream Compatibility
Possible units, which may be placed downstream from the printing base, would be an
extension table (BK703), a tabber (BK730) or even another printing base. The required
communication with a downstream device is carried out over the BK7IB-2’s downstream
connector (JB4, at the rear of the machine).
The functions found on the downstream connector are basically the same as for the
upstream connector, although the configuration is different. The DOWNSTREAM
connector of the BK7IB-2 is configured to communicate with the UPSTREAM connector
of the downstream unit. The control signal for a downstream drier is also provided on this
connector.
A separate 7-pin connector (JB5 at the rear of the BK7IB-2) is provided for a Buskro
Conveyor. This connector only has a provision for a Stop signal from the conveyor to the
BK7IB-2. However, the speed control circuit for the conveyor is actually part of the
BK7IB-2 and thus the drive voltage for the conveyor motor also has to be sent over the
connector. This permits the BK7IB-2 to provide such features as Stack Control (i.e.
providing gaps between certain stacks of mailpieces for sorting or bundling purposes).
If there is no unit downstream from the BK7IB-2, other than a conveyor, then the sensing
circuit for the Stop button has to be set to DISABLE , or the BK7IB-2 cannot run. This
function is performed by switch S1-3 on the Base Control Board.
The same function for the conveyor is provided by S1-1 , the CONV DISABLE/ENABLE
switch. If a conveyor is not present in the system, S1-1 has to be set to DISABLE .
