Ethernet Connectors
The Ethernet IN and OUT ports use standard Ethernet RJ45 CAT5e, M8-A or M8-D connectors depending on the motor variant. They are labeled IN and OUT but either port may be used.
The CM1-T Ethernet connections will act as a TCP/IP switch, allowing multiple . Multiple motors or other devices to can be connected in a daisy chain configuration without the need to run a separate ethernet connection back to a central demarcation for each motor. switch for each ethernet device.

Example Cables
All ethernet cables are standard pinouts and are available from a variety of online suppliers or cable houses. Here are a few example cables from the Phoenix Contact NBC series
| Image | Part Number | Description | Digikey Link |
|---|---|---|---|
| 1407353 | M8-A male to RJ45 | Digikey - 1407353 |
| 1407349 | M8-A male to M8A male | Digikey - 1407349 |
| 1227562 | RJ45 to RJ45 | Digikey - 1227562 |
Power Connector
The power connector supplies 24V to the TCP/IP slave and the motor separately. These two can be tied together so both are off the same power supply.
