Issue
Which Ethernet port speeds are supported by Sigma controllers?
Product Line
Satchwell SigmaEnvironment
- Sigma controllers
- Ethernet
- New Hardware. ARM 7(S-696, S-x96CPU-AE, S-796, S-x796CPU-AE, S-DNN3, S-DNN3-DT, S-632-E, S-632-AE and S-IC3's)
- Old Hardware V53 (S-ETH, S-496, S-596, S-532, S-DNN and S-IC's)
Cause
The newer ARM-7 controller hardware supports more Ethernet connection speeds than the older V53 controller hardware.
Resolution
Most Ethernet hubs or switches autoscan to find the best connection speed.
For Sigma device hardware types, the supported Ethernet speeds are as follows:
ARM-7 (New hardware):
- 100Base-T (and supports port auto-scanning on connection)
- 100M Half Duplex
- 10M full/half duplex
V53 (Old hardware):
- 10Base-T (does not support port auto-scanning)
- 10M half Duplex
Additionally, for direct connections to a Sigma controller:
- ARM-7 Ethernet connection supports both straight and cross-over Ethernet cables.
- V53 hardware only supports cross-over cables.
