MDB Bill Acceptor (BA) and MDB Coin Changer (CC) protocol to RS-232
serial protocol. The IU functions as a slave to a master
control system. The master may be any control system that supports
RS-232 serial communication, for example
a PC. DESCRIPTION:This Interface Unit (IU) is
designed to convert the MDB Bill Acceptor (BA) and MDB Coin Changer
(CC) protocol to RS-232 serial protocol. The IU functions as
a slave to a master control system. The master may be any
control system that supports RS-232 serial communication, for
example a PC. OPERATION: The master and
slave communication is based on master requests and slave replies.
The master sends a status request (or command) to the IU and
IU answers by sending its current status. The IU's typical response
to the Master's request (polling) consists of a header and
data bytes. If there is no BA or CC activity, the status is one
byte, the header only. When the IU receives data from the BA or CC,
it sends a header followed by data bytes in the response to
master's status request. The master must always poll (query) the
IU. If the IU does not receive a query from the master in the
predefined time slot or IU does not recognize master messages 10
times in row, it will inhibit the BA and CC acceptance. At power
up, acceptance of the BA and CC is
inhibited. Nomral Package
