Jumper Settings Appendix A-3
A.2 Ethernet Jumpers
The EcoLAN 2000E has three jumpers that affect Ethernet operations: Automatic/
Manual (JP4), Manual Selection (JP3), and Collision Threshold (JP5).
The Automatic/Manual jumper causes the EcoLAN 2000E to select Ethernet net-
work type automatically when in the AUTO position. In the MAN position, the net-
work type is selected by the Manual Selection jumper.
The Manual Selection jumper allows the user to force the EcoLAN 2000E to operate
from the indicated connector. Note that with the Manual-10BaseT connection, the
card will operate 10BaseT without the support of the LINK connect signal.
The Collision Threshold jumper is for Thinnet interfaces only. The 10BaseT Ethernet
interface does not use this jumper. The default setting is TX for Transmit Threshold.
You may wish to change this jumper to RX (Receive Threshold) if you are using the
Thinnet interface and you wish to adjust the collision threshold.
