HP 100LX Connectivity Pack: Common Reasons for Not Connecting
Listed below are some of the most common reasons why the Connectivity
Pack isn't working, and their solutions.
The part of the cable that plugs into the 100/200LX has a bump on it and
also an HP logo (as long as it is an HP cable). This bump and logo should
face UP when plugging into the Palmtop. It can be placed in upside down
(don't try this!) but no connection can be made. This happens quite often.
1. The cable is in upside down.
The 95LX cable end and serial port are shaped like a rectangle with
rounded corners on the bottom. It is difficult, but possible to put the
cable in upside down.
These must match. Use the highest one that connects so that transfers will
go as quickly as possible.
2. The Baud rates on PC and HP Palmtop are different.
Sometimes certain PC's have trouble with the higher baud rates. Lower the
baud rate on both machines. Usually this is only encountered while in Windows.
3. The Baud rate is too high for PC.
On the Palmtop, COM1 is the port to select for cable connections. Infrared
communications can only be used with other Palmtops and certain PC's that
have a built-in infrared port. COM2 and Alternate on the Palmtop cannot
be used with CPACK.
4. The wrong serial port is selected on PC or Palmtop.
On the PC, set the port to the port to which the cable is physically
The adapter must switch pins 2 and 3. The adapters in the Connectivity
Pack that will accomplish this are numbered 5181-6641 (has icon of a computer
on it) and 5181-6640 (has an icon of a printer on it).
5. You are using the wrong cable adapter on the PC.
Rebooting the Palmtop is not enough to unlock the palmtop serial port.
Instead, follow these steps:
6. The Palmtop's serial port is locked-up.
An interrupt allows the Palmtop to read the status of the serial port and
interrupt it, if necessary. Don't change the Palmtop's interrupts. On the
PC, sometimes COM 3 and 4 are using non-standard interrupts and the Connectivity
Pack software on the PC must be told which ones to use. For example, the
HP Vectra series of PC uses interrupts of 10 and 11 rather than the standard
4 and 3. This is changed in the Connectivity Pack software's SETUP application
by pressing (ALT) Options, Communications Port, tabbing down to the Interrupt
box and select the desired number.
A. Disconnect the serial cable.
B. Close all applications on the Palmtop by pressing (MENU) Quit in each
one. On the 100LX you can press (&...) (MENU) Application, Close All.
When Topcard is showing the owner's name and title, all applications are
C. Turn the Palmtop off.
D. Hold down (ESC) while pressing and releasing (ON), then release (ESC).
This places the unit in TEST mode.
E. Highlight Wire serial port and press (ENTER). In about 2 seconds the
words no loop should appear to the left of the highlight bar. This action
resets the serial port. If any other words show to the left of "wire serial
port" then the unit may require service.
F. Press (ESC) to both exit and reboot the Palmtop.
7. The wrong "interrupt" is set on the desktop PC.
Also, there is sometimes an Interrupt conflict with a built-in modem
or CD-ROM. If COM3 uses Interrupt (IRQ) 4 and COM1 is active (mouse or
modem) CPACK100 can fail to connect. The same is true for Com4 /Com2 which
often share IRQ 3. Change the Interrupt on the COM port you wish to communicate
through in the SETUP application of the Connectivity Pack.
Change the drive letters of the Local drives to letters that are not being
used already, and are within the LASTDRIVE setting in your CONFIG.SYS file.
This is done in the Connectivity Pack SETUP application by pressing (ALT)
Redirector Client Settings Advanced. Sometimes network software will cause
COM 3 and 4 to not function.
8. The 100LX Connectivity Pack Redirector is conflicting with Network or
Doublespace drives on your desktop PC.
This may mean that the PC has very little memory to work with, but much
more likely it indicates a misplaced Connectivity Pack file on the PC.
When the Connectivity Pack is first started it will display icons for the
various applications available.
9. The "Not enough memory to open application" message appears when the
100LX Connectivity Pack version of FILER is started on your desktop PC.
There should be only 11 icons displayed on the HP 100LX Connectivity
Pack's AppManager screen (the opening screen). If more icons are showing,
such as LOTUS or WORLD-TIME, press (ESC) to clear the error message and
then press the letter D to go into DOS. This should place you in the CPACK100
directory. Type del appmgr.lst and press (ENTER). This will delete the
file that is causing the problem. (This file controls the icons that you
have set up on the Palmtop and resides in the C:\_DAT directory. It should
not be transferred to the CPACK100 directory on the PC).
