35 Troubleshooting

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

1. Are you using a Palm Tungsten C, LifeDrive, or TX? 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/A and Palm Tungsten C.

36 Enable “Encryption” Function

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

1. Connect the Palm Tungsten C to the LI-8100/A 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.

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

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