Description
The FRM Series gives you the option to choose from the most popular ber cabling
connectors. The FRM220-10/100 provides you with ST, SC or FC connectors for your ber optic
cables and RJ-45 port for 10/100Base-TX twisted pair cable connection. The factory default
settings of Ethernet auto-negotiation may be modied by adjustment of external DIP
switches to force Full/Half 10/100 or LFP function settings. The FRM220-10/100 gives you the
freedom to extend your 10/100Mbps cabling distance by allowing connectivity up to 120
kilometers over ber. Six LED indicators signal the power status of the converter, UTP port
speed, Link/Act, duplex status and FX port ink/Act
and FEF (Far End Fault).

10/100BASE-TX RJ-45 Connectors
One RJ-45 connector is provided for connection to MDI-X (To PC) or MDI (To HUB) equipment.
Auto MDI-X allows all UTP connections to be made using only a common straight-through
UTP cable.
100BASE-TX UTP Cable
Cable type: 100Base-Tx; Category 5 or better
Maximum cable distance: 100 meters (328 feet)
Fiber Optic Connectors
Two connectors are provided for ber optic cable connection.
One is labeled "Tx" for transmission of optical data, the other is
labeled "Rx" for reception of optical data.

Connect the Ethernet cable to the FRM220-10/100I Series. The converter will sense
whether to operate in Full or Half mode and will be indicated on the LED. Follow the
connection examples below. Install the ber converter with the DC power adapter
provided (+12VDC, 1A) and connect the adapter to an AC outlet.
Installation
The following example illustrates the connection scheme when connecting from a
100BASE-TX port of one HUB to a 100BASE-FX port of another HUB through the ber
converter.

Link-Fault-Pass through (LFP) Application Note
When ‘link fault pass through’ function is enabled, link status on TX port will inform the FX
port of the same device and vice versa. From the link fault pass through explanation in the
gure below, if link fail occurrson TX port (1), the local FX port sends non-idle pattern to notify
the remote FX port (2). The remote FX port then forces its TX port to link failed after receiving
the non-idle pattern (4). This mechanism will alert the link fault status of local TX port to the
remote converter's TX port, and the link status of the remote TX port will become down. Link
status LED will also be o for both. Link Fault Pass through is enabled by setting DIP switch 4 (ON).
