troubleshooting guiDe

1. Problem: LTC2874 program doesn't download and

install automatically.

Solution: Get the latest QuikEval software either by

updating QuikEval from its pull-down menu (Tools >

Update Program), or by installing the latest version

directly from: www.linear.com/software.

2. Problem: DC590 controller board not detected.

(Error 1)

Solution: Connect to PC using USB A/B cable.

3. Problem: LTC2874 not detected. (Error 2)

Solution: Ensure that the DC590 ribbon cable is con

nected and that VL power is applied. See Table 1.

Problem: Unsuccessful communication with the

LTC2874. (Error 5)

Solution: Check DC590 ribbon and USB connections.

Usually, this error indicates that one was disconnected

while the program was running.

5. Problem: Invalid value read from the LTC2874.

(Error 6)

Solution: Ensure VL supply power is applied correctly.

Referring to Table 1, check LDO jumper on the DC1880A

and JP6 on the DC590.

6. Problem: GUI is gray-colored and inactive.

Solution: Press Connect button.
