Table 5: Connector for D-Sub (2-wire ethernet)
The 1000BASE-T1 connector supports both A0 (legacy) and A2 (IEEE-compliant) mode.
If no link established, the device changes the mode of operation randomly between A0 (legacy) and A2
(IEEE compliant). The link should be established in 1-2 seconds. The LED IEEE(A2) indicates the current
mode of operation.
NOTICE
The maximum allowed length of the 1000BASE-T1 cable is 30m.
