Function Possible Settings Factory
Setting
1 100 LAN rate ON – 100 Mbps
OFF – 10 Mbps
ON
2 FDX LAN duplex mode ON – Full duplex
OFF – Half duplex
ON
3 AN Autonegotiation mode ON – Autonegotiation is enabled. Maximum LAN port level is
advertised at 100 Mpbs, full duplex.
OFF
– Autonegotiation disabled. Speed and duplex mode are
determined by the 100 and FDX switches.
ON
4 FIL 1 LAN Filtering mode. ON – Only frames destined for another LAN are transmitted
over the WAN
OFF – All frames are transmitted over the WAN
ON
5 FP Fault Propagation ON – If the CTS (RS-530, V.36, V.35, V.24), or Indication (X.21)
signal is not received at the WAN side or LOS condition is
detected (4-wire), LAN link is shut down.
OFF – LAN link status does not depend on any signal on the
WAN side.
OFF
6 FLC 2 Backpressure/Flow
control ON - Backpressure/flow control are enabled for half duplex/full
duplex respectively
OFF - Backpressure/flow control are disabled for half duplex/full
duplex respectively
ON
7 LNG LONG (for 4-wire
interface version only) ON – 4-wire link operates at 5 Mbps
OFF – 4-wire link operates at 10 Mbps
OFF
Note 1: Reset TinyBridge-100 to put changes in the filtering mode into effect.
Note 2: Enable autonegotiation to put changes in the flow control mode into effect.
When powering up the TinyBridge-100 with flow control disabled, enabling flow control requires resetting
TinyBridge-100.
Connecting the LAN Interface
• Connect the user LAN to the RJ-45
connector of TinyBridge-100. Automatic
MDIX allows using straight or crossed
cables for the LAN connection.
Connecting the WAN Interface
• Connect the 25-pin female connector
of the unit to DCE equipment, using the
supplied adapter cables (see Table 3,
Table 4, or Table 5 for pinout details)
Connecting the 4-Wire Interface
Warning: Do not apply power to the TinyBridge-100
until the 4-wire terminal block is connected as
described below.
1. Remove the protective cover from the
terminal block.
2. Unplug the terminal block from the
TinyBridge-100.
3. Feed the 4-wire cable through the protective
cover and connect the Tx and Rx wires to
their respective terminals, as illustrated in
Figure 7. If the cable is shielded, connect the
shield to the GND terminal.
4. Check that the wires are secure and
reconnect the terminal block to its socket.
5. Place the protective cover in position over
the terminal block.
IMPORTANT
: When two 4-wire
TinyBridge-100 units are to be connected
directly, the terminal blocks should be wired
so that the Rx terminals of each
TinyBridge-100 connect to the Tx terminals
of the other unit.
