Specifications

The PK-232 uses the 1,000 Hz wideshift filters which have a center
frequency of 1.7 KHz for copying facsimile transmissions. As a
result, you must tune 1.7 KHz lower than the frequencies listed in
Table 1 when using Upper Sideband. Similarly; in Lower Sideband, one
must tune 1.7 KHz higher than the frequencies listed in the table.
The PK-232 LED bar-graph should be tuned so that the facsimile signal
is roughly centered in the display as shown in the middle of Figure 1
below. If the audio frequency is too low, the bar-graph will look
something like the left-most display. If the audio frequency is too
high, it will look something like the right-most display. Facsimile
tuning is not especially critical when copying WEFAX, but a properly
tuned signal is needed when printing facsimile photographs.

9.3.3 PK-232 Facsimile Parameter Settings
To start receiving WEFAX broadcasts on your computer screen, follow
the setup instructions in your PAKRATT WITH FAX program manual.
To start receiving FAX on your graphics compatible printer, you first
must tell the PK-232 that there is a parallel printer connected by
issuing the command PRCON ON. The PK-232 will respond with:
PRCon was OFF
PRCon now ON
At this point you will observe that the STA, CON, STBY, and PKT LEDs
are on. The MULT LED may also be on if the printer is "Off Line" or
is not connected to the PK-232. This is normal whenever the printer
command PRCON is ON and is nothing to worry about. Turning PRCON OFF
will return the LEDs to their normal status indicating function.
Now all that is necessary is to put the PK-232 into FAX mode by typing
FAX. The PK-232 will respond with:
Opmode now FAx
9.4 Receiving Facsimile Broadcasts
The PK-232 is now in the Facsimile Standby-Receive mode which means it
is waiting for a synchronization signal from a facsimile transmitter
to begin a new picture. Verify this by entering the OPMODE command.
The PK-232 should respond with:
Opmode FAX STBY RCVE
