6.5 Terminal
To connect a serial terminal (according to the device
model), use the RJ45 connector of the LAN-CPU. Via
the serial terminal connection it is possible to con-
figure parameters with a command line interface. You
have to use a CAB-CONSOLE-RJ45 cable to establish
a connection to your PC or Laptop computer. You can
use e.g. the standard Hyperterminal program shipped
with your Windows operating system. Configure your
terminal program with 38400 Baud, 8 Databits, no
parity and 1 Stopbit. The terminal emulation have to
set to VT100. After connecting to the timeserver there
will be displayed the login message (press RETURN
