Hardware Interfaces
Power Input
The SIO06 is supplied via an M12-4pin-A-coded (male) connector. The following picture shows the power supply connector location.
Pinning of power supply connector:
| Pin | Signal Designator | Signal Description |
|---|---|---|
| 1 | Vin+ | Pos. supply voltage |
| 2 | N/C | Not connected |
| 3 | Vin- | Neg. supply voltage |
| 4 | Vin- | Neg. supply voltage |
Ethernet Interface
The SIO06 provides a 100MBit/s Ethernet interface via an M12-4pin-D-coded (female) connector.
Pinning of Ethernet connector:
| Pin | Signal Designator | Signal Description |
|---|---|---|
| 1 | TD+ | Transmit (Diff +) |
| 2 | RD+ | Receive (Diff +) |
| 3 | TD- | Transmit (Diff -) |
