1. What are the settings of the parallel port for
the PPS?
The PPS is using the parallel port to communicate with the pager.
The required settings of the parallel port are as follows:
IO Address: 0378
Printer Mode: EPP/ECP or Bi-Directional
You may follow the procedure below to view the parallel port
settings:
- Select Control Panel -> System -> Hardware
-> Device Manager -> Ports (COM
& LPT) -> ECP Printer Port (LPT1)
-> Properties -> Resources -> I/O
Range -> Settings (0378…)
 
If the IO address is not correct, you may follow the procedure
below to change to the correct setting:
- From the PPS, select Settings -> Setup Port
-> Address (enter the correct IO address as specified
by the system)
If the printer mode is not correct, you may follow the procedure
below to change to the correct setting:
- Restart your machine.
- Press F10 to enter the Setup during system booting.
- Select Advanced -> Device Options ->
Printer Mode (use the right arrow key to select either EPP/ECP
or Bi-Directional).
- Save the changes and exit.

2. The PPS cannot open parallel port when it is
launched.
The possible causes of this problem are as follows:
- Incorrect parallel port address.
Ensure that the parallel port address is correct. From the PPS,
click Settings -> Setup Port and change the
address according to your PC specifications. The default value
is 0378.
- Software installation without administrator right in Windows
2000 or XP Professional.
Uninstall software, log in to Windows as administrator, and
install software again.
- Programmer driver for Win2000 or XP is not installed.
Obtain the driver from our Web site at www.daviscommsusa.comand
follow the instructions to install the driver.
- Conflict with other external peripherals attached to the PC.
Disconnect the external peripherals, restart the machine, and
try again.

3. The PPS is shutdown by Windows operating system
when read or write operation is performed.
The PPS is making use of timer for read and write operation.
The default timer used is high resolution timer, which may not
be supported by certain systems. In this case, user may select
the multimedia timer from the Setup Port under the Settings
menu. With multimedia timer, the read and write operation
will be slower.

4. The PPS cannot communicate with the pager when
read or write operation is performed.
The possible causes of this problem are as follows:
- Wrong parallel port configuration.
From the PPS, click Settings -> Setup Port and

- Cables are not connected.
Check to see that all cables are connected properly.
- Incorrect programmer box version.
Ensure that you are using the parallel version of the programmer
box and not the serial version.
- No power supplied to programmer box.
Check to see that the programmer box is connected to the power
adapter, and that the power adapter is plugged into a working
power socket.
- Device not responding.
Remove pager from the cradle. Insert a size AA battery BACKWARDS
into the pager and wait for 2 seconds. The pager has now been
reset. Remove the battery and reconnect the pager to the programmer.
