Command.
For detailed information and full protocol specification, please refer to www.cctalk.org.

Encrypted ccTalk uses 16 bit CRC checksum.
If the encryption is disabled, the user can select either simple 8 bit or 16 bit CRC checksums.
4.3.3 MDB (Multi Drop Bus)
MDB is a serial bus interface commonly used in electrically controlled vending machines. This
is a 9600 Baud Master-Slave system where the NV200 banknote validator is a slave to a
master controller. A Vending Machine Controller (VMC) has the capability of communicating
with 32 peripherals or slaves.
Connections:
To use the NV200 in MDB mode, an IF5 external interface is required. The IF5 regulates the
power supply and opto-isolates the communication lines.
