MEANING AND EFFECT
OF LIGHTS AND SWITCHES
The
li~hts
and switches on the front panel of the
TermiNet 300 Printer which are available to the
operator are shown in Fig. 7.
These lights and
switches, from left to right, perform the following
functions.
I.
LOCAL
As long as power is applied to the TermiNet 300
Printer, the LOCAL button will turn the printer
motor on.
This will allow local operation to be com-
plete, but will not allow a data set to answer a call.
For an exact description of the effect of Local on
the data set leads, refer to Table 1.
2. STANDBY
Whenever the TermiNet 300 Printer is in "Stand-
by",
the STANDBY button is lit and the unit is com-
pletely operational, but the printer motor is not run-
ning. All electronic functions are operable and the
TermiNet 300 Printer will respond to a data call.
3. ON LINE
The ON LINE push button is lit when the Terminal
is accessible or connected to the communication
link and the printer motor is running.
The only
difference between the "On-line" and the "Standby"
condition is whether or not the printer motor is
runnIng.
4. INTERRUPT
If the INTERRUPT button on the front panel is
depressed,
a BREAK or INTERRUPT Signal is
transmitted.
This signal is a 268-millisecond
spacing signal. When this button is operated locally,
the INTERRUPT light will not turn on.
If an inter-
rupt or BREAK signal is received, the INTERRUPT
light turns on.
The TermiNet 300 Printer identifies
a BREAK or INTERRUPT signal as one full charac-
ter of spacing including the start and stop bit tin1e.
The printer can continue printing after receipt of a
break or interrupt. However, the keyboard is de-
energized until corrective action has been taken. The
corrective action necessary in this case is to depress
the lighted INTERRUPT switch, which will restore
the TermiNet 300 Printer to its normal condition.
