Converter

Warning: Be sure to turn off and disconnect your equipment's power cords
         before making any connections. Connecting cables with your
         equipment turned on might damage the cables and the equipment. To
         discharge any static build-up, touch a grounded metal object before
         you being to connect the equipment.

1. Plug the serial cable into the serial equipment. Secure the connection
   with hardware included with your serial cable.

2. Plug the serial cable's DB-25 female connector into the converter's SERIAL
   port. Secure the connection with the hardware included with your serial
   cable.

3. Plug the parallel cable's DB-25 male connector into the converter's
   PARALLEL port. Secure the connection with the hardware included with
   your parallel cable.

Caution: Be sure to connect the converter's serial side to serial equipment
         and the converter's parallel side to parallel equipment. Failure to
         do so will result in damage to all connected equipment. Place the
         converter on a flat surface to ensure there is no tension on the
         cables.

4. Plus the parallel cable's other end into your parallel equipment. Secure
   the connection with the hardware included with your parallel cable.

5. Plug the AC/DC adapter's small round plug into the converter's adapter
   jack.

Caution: Use only the supplied power adapter. Using an inappropriate adapter
         might damage the converter and your connected equipment.

6. Plug the AC/DC adapter's large plug into a standard AC outlet.

7. Reconnect the equipment to an appropriate power source.

OPERATION

Send data from the equipment's serial port as usual.

Send data from the equipment's parallel port as usual.

Note: This converter does not function with serial equipment designed to echo
      messages back to the computer (such as a plotter's working parameters
      or status) because the parallel interface can only pass data in one
      direction. Refer to your serial equipment owner's manual to determine
      if this condition exists in your serial equipment.
