6.2 Connection over a DKO 011or DKO 013:
If both DIAS bus connections to the S-IPC are needed, a DKO 011 or DKO 013 can be
used in combination with a DPS 001 power supply module.
Wiring the DIAS modules with a DPS 001:
o
Left: DPS 001 power supply module
o
Right: DKO 011 or DKO 013 adapter module
Wiring the S-IPC:
o
X18: DIAS bus to CIC interface modules or bus termination (2 x 100 Ω )
o
X19: Connection to DKO 011 or DKO 013 adapter module
7. CAN Bus Termination
In a CAN bus system, both end modules must be terminated. This is necessary to avoid
transmission errors caused by reflections in the line.

If the S-IPC is an end module, it can be terminated by placing a 150-Ohm resistor between
CAN-A (LOW) and CAN-B (HIGH).
The bus termination on the CAN terminal is installed before delivery!
