Now run initflam.pl at the flamingos1a prompt. You do not need to close any of the daemons to

rerun initflam.pl for this problem. At the start, initflam.pl will complain that the motor and

mce4 daemons are not up and listening, and ask if you want to continue. You do want to continue, as the

daemons were working properly before the crash of MCE4. MCE4 must be reinitialized, in order to set

the proper clocking of the array. If you were taking a spectrum, you need to reset the bias to 0.75 V.

After it has successfully initialized the EDT frame grabber (where it says “do you see 10 lines of text

between a line saying opening pdv unit 0 and a line saying done”), it will ask if you want to

continue. You can type y at this point.

Next, you need to take two junk frames with short exposure time (e.g., 3 seconds). The first frame after

repowering and initializing MCE4 will look like a bad read; however, the second frame should look

normal.

b) Problem: The image will not read out. A communication error message appears.

The following error message appears during the integration:

UFClientSocket::connect> unable to connect to flmn-4m-1a, port #

52008Connection refused

ufdc> unable to connect to MCE4 command server agent...

Solution: The fiber optic serial communications between the perle and the MCE4 controller may have

been switched off inadvertently. There are two fiber converter units, one below the MCE4 controller on

the left-hand rack, the other below the perle on the right-hand rack (Figure 2, below). Each has two small

toggle switches, which must be set so that the red and green LEDs are OFF. The LEDs are used only for

testing that the fiber is working.
