I/O Connector (CNR6)
The CNR6 connector is for digital I/O connection. Take out the green 16-pin connector (CNR6) from the
accessory kit, and connect prepared AWG 16 wires to pin 1~16 of this connector as shown in figure 25. It’s
recommended to substitute the wires with a multi-core shield cable. The shielding layer should be crimped
with ring terminal whose diameter D=5.5. And the ring terminal need be connected to a grounding screw as
shown in figure 24
.

The 4 dry contact outputs are programmable. They are reserved functions. The state of contact outputs
（short or open） can be configured according to the customer's requirements. Similarly， the wet inputs
detect the state of contacts from the customer. They are also programmable according to the requirements.
A customized FW revision is needed to realize both the dry outputs and wet inputs function.
The Remote EPO connector is also a wet input from custom. Only normal close EPO is supported. When
the function is reserved, the shorting stub between CNR6-15 and CNR6-16 should be retained.
