This Quick Start Guide provides a concise series of steps to get a pair of the NCB modules “up and running”
quickly so that initial operation may be confirmed.
It is important that all L ON W ORKS devices attached to the “NETWORK” connector of any one NCB module
use the same network transceiver . See “L
ON W ORKS N ETWORK T RANSCEIVERS
” in section “1.
I NTRODUCTION
”.
In the following steps, identify the two units as “NCB Unit 1” and “NCB Unit 2”.
Switch Settings

For use in Dial-up mode, set the OPTION A switches on both NCB units as follows:
Switches 1 through 4 and 6 through 8 : UP
Switch 5 : DOWN

For use in 2-wire Leased-Line mode, set the OPTION A switches as follows:
Switch 1 : DOWN on NCB Unit 1 and UP on NCB Unit 2
Switches 2, 5 and 7 : DOWN
Switches 3, 4, 6 and 8 : UP
Module Connection

Connect L ON W ORKS network devices to the “NETWORK” connectors of each NCB unit (both RJ45s
and the terminal strip are in parallel). If using the RJ45 connector(s), connect to pins 1 & 2 (the right-
most two pins) and use caution, as other pins on these connectors carry DC power.

If using Dial-up mode, connect the “LINE” connector of each NCB unit to a standard analog
telephone line using the telephone cables supplied with the NCB modules. If using Leased-Line mode,
connect the “LINE” connectors on each NCB together using one of the telephone cords provided with
the NCB modules.
 If optional handsets were included with the NCB units, connect one to the “AUDIO” connector of each
NCB.
 Connect power to the NCB units via the front panel “DC IN” connector.

If using dial-up mode, the NCB units are ready to be given a dialing command. Proceed directly to
“Step 4. Implementation in a Network”in section “2.
S ETUP AND O PERATION
”.

If using Leased-Line mode, the “OH“ LED will light on both NCB units and the modems will
automatically begin the training sequence. If optional handsets are connected, the training process can
be monitored with them. Within 10 seconds, the “CD” LEDs on both NCB units will light, indicating
a successful connection. The modules are now ready for use. Any LonTalk packets entering one NCB
unit will exit the other and vice-versa. Disconnecting, then re-connecting the telephone cable will
cause the connection to be dropped, then automatically re-established.
NOTE: If using Leased-Line mode, this quickstart setup includes connecting the NCBs
“back-to-back” using 2 wire mode and a reduced transmit level. In an actual leased-line
installation involving longer telephone cable lengths, change OPTION A Switch 7 to UP to
configure the NCB’s modem to output full transmit power, and set OPTION A Switch 8 UP
for 2-wire mode or DOWN for 4-wire mode.
