INSTALLATION

Configuring TinyBridge-100

1.Identify switches on top panel of TinyBridge-100.

2.Set switches according to Table 1.

Table 1. DIP Switch Settings

Switch	Switch	Function	Possible Settings	Factory
	Identity			Setting
1	100	LAN rate	ON – 100 Mbps	ON
			OFF – 10 Mbps
2	FDX	LAN duplex mode	ON – Full duplex	ON
			OFF – Half duplex
3	AN	Autonegotiation mode	ON – Autonegotiation is enabled. Maximum LAN port level is	ON
			advertised at 100 Mpbs, full duplex.
			OFF – Autonegotiation disabled. Speed and duplex mode are
			determined by the 100 and FDX switches.
4	FIL1	LAN Filtering mode.	ON – Only frames destined for another LAN are transmitted	ON
			over the WAN
			OFF – All frames are transmitted over the WAN
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	OFF
			WAN side.
6	FLC2	Backpressure/Flow	ON - Backpressure/flow control are enabled for half duplex/full	ON
		control	duplex respectively
			OFF - Backpressure/flow control are disabled for half duplex/full
			duplex respectively
7	LNG	LONG (for 4-wire	ON – 4-wire link operates at 5 Mbps
		interface version only)	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.
