6.17 COMMONLY ASKED QUESTIONS
1.How far can I have the Controller from the computer?
-
The official specification for parallel cables recommends a length not
greater than 10 feet (appr. 3 meters), however you can probably use a
cable up to 25 feet (appr. 8 meters) without encountering any line
communication problems.
-
The official specification for serial cables recommends a length not
greater than 50 feet (appr. 16 meters), however you can probably use a
cable up to 100 feet (appr. 30 meters).
-
The AppleTalk specification recommends a cable length of not greater
than 1000 feet (appr. 300 meters) which should not be exceeded.
2. How far can I have the Controller from the Priport?
-
The official specification allows for a 10 foot (appr. 3 meter) cable. A 6
foot (appr. 2 meter) cable was supplied with the Controller, but you can
probably use a cable up to 20 feet (appr. 6 meters) if necessary. The
potential for line communication problems are greater the farther the
Priport is from the computer.
3. Which is faster--the serial port or the parallel port?
-
The parallel port connection on the back panel of the Controller will
receive data from the computer as much as eight times faster than the
serial connection. However, because of the higher data transmission
rate, you are limited to a maximum parallel cable length of 25 feet
(appr. 8 meters).
4. How many computers can you run from the Controller?
-
Three. One IBM or compatible connected to the parallel port, one IBM
or compatible connected to the serial port, and one Apple Macintosh or
Macintosh network connected to the AppleTalk port.
5. Will the Controller work with a laptop or notebook computer?
-
Yes, all computers connect to the Controller as if it were a standard
computer printer.
6. Is any special wiring required for the Controller?
-
No, it will work on 110 or 220 volt systems by using the appropriate
power cord.
