Installation Guide
Fiber Optic Interface
The following “twister” models support 10BASE-FL segments via ST or SC
connectors.
• The 2111-13-B provides one set of FL multimode SC connectors, which
support a maximum segment length of up to 2 km for remote links.
• The 2111-15-B provides one set of FL multimode ST connectors, which
support a maximum segment length of up to 2 km for remote links.
When making fiber optic connections, be sure that the transmitter (TX) on
the “twister” connects to the receiver (RX) on the connected device and that
the transmitter (TX) on the connected device connects to the receiver (RX)
on the “twister” unit.
Once power is applied to the unit, correct connectivity can be verified via
the LK LED.
