Troubleshooting the 35900E
Verify the 35900E is Ready for Operation
At power up, the 35900E automatically executes internal self-tests to determine
the amount of memory installed and to verify that the main power, system
memory, and the MIO communication interface, and other internal circuits are
operating properly. These tests take about 30 seconds for a 1-MByte system.
The FAULT light will blink ON/OFF during this time.
When the 35900E has completed the internal self-tests, verify that:
1. the FAULT lamp is OFF
2. the POWER indicator is ON
3. no other indicators are blinking
In Case of Difficulty
If the 35900E does not power up correctly, turn power off and check the
following:
1. Rear panel configuration switches 3 through 6 are DOWN (for normal
operation).
2. MIO card is correctly configured for host computer communications.
3. MIO card is connected to host computer or network.
4. Analog signal cables are connected.
5. Remote control cables are connected (if needed).
6. Digital I/O cables are connected (if needed).
7. Power cord is connected.
