16BIT 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.
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:-
Connecting systems together on CAN
All Traka systems and Access Pods on CAN are connected using only a single pair (2 wires) from a standard
Category 5 twisted pair network cable. Ideally they should be daisy chained together on a single long bus.
In some installations it may not be possible to daisy chain all systems together and some maybe "spurred" off the
main bus. Contact Traka for advice on the best wiring method in this instance.
