Patton electronic 2158 Configuring DIP Switch S1, Switch S1-1 Ethernet Auto Sense, S1-1 Setting

4.2 CONFIGURING DIP SWITCH S1

DIP switch S1 is where you configure the CopperLink line rate, symmet- ric or asymmetric, Ethernet full auto negotiation capability (100Base-T full or half duplex, 10Base-T full or half duplex) or limited auto sense (only 100Base-T half duplex, 10Base-T full or half duplex).

Switch S1-1: Ethernet Auto Sense

Use switch S1-1 to configure the unit for full auto sense capability or lim- ited auto sense capability. Full Auto sense capability consists of standard Ethernet Auto sensing (100BaseT full duplex, 100BaseT half duplex, 10BaseT full duplex, and 10BaseT half duplex). Limited Auto sensing capability consists on only auto sensing for 100BaseT half duplex, 10BaseT full duplex, and 10BaseT half duplex. The limited auto negotia- tion feature is used when an Ethernet device does not comply with IEEE 802.3x (back pressure flow control) at 100M full duplex.

Switches S1-2 and S1-4: Data Rate

Use switches S1-2 and S1-4 to configure the CopperLink line rates.
