    The PCA-6148/6148L features an internal Flash/RAM/ROM disk drive. This drive emulates a floppy disk drive by using solid-state memory chips (Flash, RAM or ROM) to store programs and data instead of the magnetic particles on the mechanical drive’s disk. The Flash/RAM/ROM disk offers much faster access times than a floppy or hard disk and greatly increases reliability in harsh environments.

    POST LEDs This appendix lists the codes generated by the POST (Power On Self Test) routines. It also discusses how to read the PCA- 6148's POST LED indicators.
  • Page 102 You can also determine the number of the test that failed by reading the LED indicators on the top of the PCA-6148 board. Please make a note of any POST codes before you contact Advantech for technical support.
  • Page 103 I/O address 80H. If the test fails, the code will stay in memory. You can read the code and determine which test has failed. The PCA-6148’s POST LED indicators make this process ex- tremely easy. You don’t need any special diagnostic tools, you just read the POST code from the LEDs.
