8BIT CAN GATEWAY HARDWARE AND CONNECTIONS
Each Traka Key Management System, Locker or Access Pod requires a CAN Gateway adaptor that converts messages
from the Traka Control PCB into Controller Area Network (CAN) messages for sending over CAN.
Traka currently supports two different types of CAN Gateway adaptor. The type required depends on the card reader
as well as the other peripheral devices the system needs to support. Please contact Traka with your application
requirements and the correct device will be specified for your needs.
CAN Gateway PCB Adaptor
The Traka Shock Sensor PCB can be used to send and receive CAN messages. This type of CAN Gateway adaptor is
required when the
is used. This is because the CAN Gateway PCB does not use the UARTB
interface (unlike the CAN232 Converter) but instead connects to the Clock and Data card reader interface.
See following CAN Gateway PCB connection diagram:-
CAN232 Adaptor
The CAN232 adaptor (CAN to RS232 converter) can also be used to send and receive CAN messages and connects to
the UARTB interface. This also allows the card reader interface to be used as normal for proximity and magstripe
readers.
See following CAN232 connection diagram:-
