4.9 LTC 4681, LTC 4682 Series Modules

for Ethernet Data Transmission

NOTE: Although the LTC 4681 and the LTC 4682 are

both transceivers, one of each type must be used to

create a working ethernet fiber optic link. It does not

matter which model is used at a particular side of a

configuration.

4.9.1 Indicators / Operation

1. Set Dip Switches as Follows:

a) Dip Switch 1: AUTO NEGOTIATE –

Recommended setting is UP. When active,

speed and twisted pair connection type (mdi or

mdi-x) is automatically sensed. When disabled,

a cross over cable must be used, and both ends

of the link must be fixed at the same speed and

duplex setting.

b) Dip Switch 2: SPEED – This setting applies only

when AUTO NEGOTIATE is disabled. This

setting forces the connection speed to either

10Mbps (UP position) or 100Mbps (DOWN

position). The recommended setting is 100Mbps.

c) Dip Switch 3: DUPLEX – This setting applies

only when AUTO NEGOTIATE is disabled.

This setting forces the connection type to either

half duplex (UP position) or full duplex (DOWN

position). The recommended setting is Full

Duplex.

2. The POWER LED illuminates when AC power

is applied to the unit.

3. The FIBER LINK LED illuminates when a valid

optical link is established.

4. The AUTO NEGOTIATE ON/OFF LED

illuminates to indicate that Dip Switch 1 is set to

AUTO NEGOTIATE mode.

5. The LED at the top left of the RJ-45 ethernet

connector illuminates GREEN when a valid

ethernet connection link is established.

6. The LED at the top right of the RJ-45 ethernet

connector illuminates GREEN to indicate a

100Mbps connection speed. If the LED illuminates

ORANGE, the connection speed is 10Mbps.
