TROUBLE SHOOTING
PARALLEL PORT INTERFACE
Symptom:
No additional drive icon in “My Computer”. The EXP HD driver installed without any
incident.
Solution: 1. Check your cable connection, along with the AC adapter at the wall receptacle make
sure there is no lose connection. The green LED on the top of EXP HD assembly
should lit up.
2. Check your computer CMOS or BIOS setup. Some computer allows user to set
printer type to be: Standard, EPP Only or Bi-directional. A setting to “EPP Only” is
preferred for a better performance.
3. Check if other hardware devices are connected to the same parallel port. Daisy-
chaining with other hardware devices is NOT recommended. Other devices include
but not limited to the following: security device (key, lock), audio port, parallel-to
SCSI device, tape backup device, network device, A/B switch, printer-sharing
device.
4. If you connect the equipment in daisy-chain fashion, always turn on the device
farthest away from the computer first (in this case the EXP HD), then turn on the
device next on the chain. Turn the computer last.
