1.Setting the internal DIP
switches.
2.Configuring the DTE/DCE
shunt jumpers.
3.Connecting your devices to
the slave ports and master
port.
port.
4.Connecting the TEP to
electric power.
The TEP uses a dynamic
buffer. Each input device is given
a minimum of 1K of RAM reserved
exclusively for that port, so a
single port cannot monopolize all
of the TEP’s space. The remaining
memory is distributed among all
active ports according to the
current demand.

There are a total of 10 LEDs on
your TEP’s front panel—nine
Port-Status LEDs (numbered 0-8)
and one Power LED. The Power
LED lights up when the TEP is on.
Each Port-Status LED will flash or
blink if the corresponding port is
transmitting or receiving data. The
LED will be steadily lit if there’s a
buffer overflow on the
corresponding port. It will remain
dark if there’s no data activity on
the corresponding port. On
standard units without a 4-Port
Expansion Board, LEDs 5-9 will
remain dark.
