ATI D-sub 9 pin 120 Ohm termination adapter is a CAN adapter with a 9-pin male D-Sub connector at one end and a 9-pin female D-Sub socket at the other. Between CAN High (pin 7) and CAN Low (pin 2) there is a built-in 120 Ohm CAN terminating resistor. The ATI CAN termination adapter is used when there is a need to terminate a CAN node without internal termination or when no CAN node is connected to the bus. The ATI D-sub 9 pin 120 Ohm termination adapter has a 9-pin male D-Sub plug connector and a 9-pin female D-Sub socket. A 120 ohm terminating resistor sits between pins 2 and 7.
