SUMMARY
When using Synoptics Hubs with 10-Base-T network cards such as the Etherlink II TP, the switch settings on the card need to be modified from their factory default settings to enable the card to work properly.



MORE INFORMATION
Synoptics Hubs such as LattisNet models 3030 and 3305, the 2500 family of Workgroup Concentrators (models 2500, 2510, and 2530) date back to the pre- 10-Base-T standard days. However, they are found in many Ethernet installations and thus need to be integrated into a 10-Base-T LAN.

If you are using one of these hubs with an Etherlink II TP card, modify the following jumpers from their factory defaults to the setting indicated:                   Jumper    Factory      Synoptics Jumper           area      setting      setting ---

DC SIG          J4         OFF          ON

LINK BEAT       J1         ON           OFF

RX TH           J2         NORM         LOW

XMIT            J3         NORM         LOW This will enable the TP card to transmit successfully using the Synoptics Hubs.
