11 Troubleshooting

If you cannot establish a wireless network connection, check the following:

1. Are you using a Palm Tungsten C? Other models of PDAs manufactured by Palm, or PDAs manufactured by other companies (i.e., HP, Sony etc) will not work.

2. Did you enter the Network Name correctly?

3. Verify instrument IP address is correct.

4. Verify Palm IP address is not the same as the instrument IP address.

5. Verify the network type is peer-to-peer ad-hoc, not access point.

6. Power the instrument off, make sure the wireless card is seated properly, and turn instrument back on.

7. Shorten the distance between the LI-8100 and Palm Tungsten C.

12 Enable “Encryption” Function

In order to communicate with other devices, the LI-8100 must be given a unique IP address, a net mask, network name, and channel. Optionally, data encryption can be enabled.

WEP (Wired Equivalent Policy) is an encryption standard built into 802.11b, and is supported by the LI-8100. If data encryption is enabled, the same 40-bit (5 character) key must be entered on all devices of the WLAN. The key is used for data encryption and decryption.

1. Connect the Palm Tungsten C to the LI-8100 via the RS-232 cables. Turn on the Palm Tungsten C. Tap the LI-8100 icon. Next, tap Connect by Serial. Wait while the “Status: Querying …” process is progressing. Wait a few seconds until the Instrument Status screen is filled.

2. Tap the top of the screen and select the 8100 menu. Select Instrument Settings. Tap “Network Parameters”. The Network Name and other parameters are already entered. The Security parameter reads DISABLED. Tap DISABLED. The Set Network Security screen appears. Tap the check box next to Enable Security. Similarly, check Change Encryption Key and enter a five-character word using the keypad. Tap Send. [Warning: You must choose a five-character word made of either letters, numbers, or a combination of both.] Next to Security it should now display ENABLED.

3. Press the Home key on the Palm Tungsten C. Turn the LI-8100 off and back on. Wait for the ready light to come on.

4. Scroll down the home screen of the Palm and tap the Prefs icon. Tap Network. Tap Details. Tap Wi-Fi Preferences. Tap Info. Tap Edit network. Tap and check the WEP Encryption field. A new line will appear named WEP Key. Tap the space next to it. The Network WEP Key screen appears. Next to Key Type, choose 40-bit ASCII. On the line below WEP Key(5 characters) enter the five-character Encryption Key you used in step 2 above. Tap OK. On the Edit Wi-Fi Network screen the WEP Key now reads Assigned. Tap OK. Tap Done three times in succession. Press the Home key on the Palm Tungsten C keypad.

5. You are now ready to use the Palm Tungsten C in encrypted mode.
