Figure 2.3 RJ-11 Female Connector
The two center pins of the RJ-11 connector (pin 2, Tip; and pin 3, Ring) carry the
signal.
These connections are balanced. We recommend that these leads be shorter than 60
cm if you are using frequencies up to 4.5MHz. It is possible to use longer leads as the
frequency decreases.
WARNING
The maximum input to any DLS 6700 port must not /-100 V
or 100 mA between Tip and Ring. Exceeding these limits could damage
the unit.
2.6 DLS 6700 Remote Control
The DLS 6700 ADSL2++ Wireline Simulator is configured through its RS-232 serial
port. The reach (length) of each simulated wireline can be adjusted remotely using
configuration software.
You can use the included Spirent Communications’s GUI to configure the DLS 6700;
or you can develop your own custom configuration software using the DLS 6700 com-
mand set. This command set is covered in this manual (see Chapter 4 "REMOTE
CONTROL"), to assist you in developing custom software and scripts.
2.6.1 Connecting the Computer via the Serial Port (RS-232)
Connect one end of an RS-232 serial cable to the RS-232 connector located on the
back panel of the DLS 6700 chassis and the other end to a serial COM port connector
on the computer.
The DLS 6700 GUI supports up to 16 COM ports. It will automatically detect all serial
ports available on the control computer between COM1 and COM16. Only available
COM ports will be listed in the “Interfaces and Identification” panel of the main GUI
window. COM ports that exist on the control PC but are already open will not appear
in this list.
