1. Connect the included serial cable to the DB9 serial
port on the front of the extender and the other to
the active serial COM port on your computer.
2. Power on the extender. The self test light will stay
amber for a minute or two while diagnostics run.
3. Use Windows HyperTerminal or VT100 terminal
with the following configuration:
9600
bits/sec,
8
data bits, parity
none
, stop bits
1
, flow control
hardware
.
4. Enter the <Escape> key on the computer keyboard
and the main configuration screen should appear. If
the <Escape> key is pressed and the screen does
not appear, re-check the COM port settings and the
COM port on your computer.
5. Select #1,
configuration
from the menu which will
take you to a menu with
DSL Mode
as the #1
choice. Select DSL Mode and hit the <Space> bar
which will change the default STU-R setting to
STU-C, then hit the <Enter> key. The screen
should continue to read STU-C.
6. The unit is now prepared to be connected to the
other extender which by default should be set as
STU-R. The unit can be powered down and should
retain the STU-C setting.
7. Connect the SHDSL line to each unit and
respective Ethernet LANs. Plug units into power
outlets and power on both units.
8. Both units will execute self-test routines and will
automatically connect with each other.
9. If units fail to connect, please double check DSL
settings using HyperTerminal to ensure they are
both set the same, except for the CO/RT setting.
More detailed information can be found in the user
manual.
Ethernet Extender DSL mode settings are made by using
the DB9 serial configuration port on the front of the
extender.
At minimum, one extender must be set
to STU-C and the other extend must remain in
the default setting of STU-R.
The default configuration is for 2 wire pairs.
It makes no difference which unit is designated STU-C and
STU-R as long as they are
not both set the same
.
(STU-C is Central Office and STU-R is Remote)
Note:
Distance and speed may vary. The above table
represents the maximum performance which can be
expected under ideal conditions using 26AWG twisted
pair copper wire.
1. The SHDSL line(s) should be 24 – 26AWG
twisted pair copper wire with RJ48 terminations.
Connect each extender to the SHDSL line.
2. Ethernet LAN(s) should be connected with CAT5
cable and will auto connect at 10/100Mbps.
3. Power on each unit and make sure one is set as
STU-C and the other is STU-R.
4. If other DSL settings are changed, make sure
both units are set the same. For example, if 1
pair of copper wire is used, both units must be
set to 1 pair. Also, if speeds are changed from
the default “
adaptive
” setting, both units must be
set to the same speed.
