TROUBLE SHOOTING
PARALLEL PORT INTERFACE
Symptom:
No additional drive icon in “My Computer”. The EXP CD 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 front of EXP CD 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 CD), then turn on the device next on the chain.
Turn the computer last.
Symptom:
The EXP CD starts to become excessively slow or behave
differently on a battery-powered notebook computer.
Solution:
If you are using a notebook or laptop computer, without the AC
adapter. The performance of the parallel port may become
sluggish and unreliable if the battery runs low. Try reconnecting
the AC adapter to your computer or recharging the battery.
Symptom:
The EXP CD starts to become excessively slow or does not
work at all.
Solution:
The parallel port on your machine may be able to a number of
different modes, standard, Bi-directional, EPP or ECP. These
different setting can effect performance of the EXP CD. In
some cases, the standard setting will even shut off signals the
EXP CD needs, while if the same port is set to Bi-directional or
EPP produce an excellent performance.
