12 Maintenance Menu and Error
Handling
12.1 Maintenance Menu
TESLA LITE has a set of utilities that provide diagnostic, recovery and TCP/
IP services. These utilities are available through the Maintenance Menu ac-
cessed with a VT-100 terminal connection to the recorder’s serial port, modem,
Ethernet LAN or USB port. For security purposes any utilities that can modify
the TESLA LITE are disabled when connecting remotely. To access these util-
ities you must connect to the recorder using Port 450 on the unit’s front panel.
Any terminal program that fully supports VT-100 emulation and provides z-
modem file transfer services can be used. HyperTerminal, which is included in
Windows XP and is also available separately as HyperTerminal PE, is used
here as an example.
1. Determine how you want to connect to the recorder.
• USB connection.
• A direct serial link connects your computer’s serial port to the recorder’s
rear panel Port 405. Port 405 is set up so that a standard, straight-through,
male-to-female serial cable can be used.
• If both the recorder and your computer have modems, you can access the
Maintenance Menu through the telephone system.
• If both the recorder and your computer are on the same LAN or WAN, you
can access the Maintenance Menu through your network.
2. Configure your terminal program as described in the table below.
• For the front.
• For a USB or direct serial link, the baud rate must be same as that of the
recorder’s port. Port 450 USB link the default baud rate is 115,200. Serial
Port 405 default baud rate is 38,400. The baud rate can be viewed and
changed in the
Utilities>Communication tab of TESLA Control Panel.
• For a modem link, the baud rate and other communication parameters only
determine how your computer talks to your modem. Usually, the fastest
possible baud rate is chosen to maximize your modem's compression ca-
pabilities.
• For a network link, only the Emulation and Font settings from the table are
relevant.
