Operating Instructions

The POD–51EH–C541U–12 supports the Siemens C541U controller which is based on the
C500 core.

This pod is supported by the 

EMUL51–PC

 Windows software version 2.1M or later. To work

with this pod, you need to choose processor C541U in the Hardware Configuration window.

The 

EPROM

 on the emulator board must be version 

COM

 1.4 or later. If it is an older version,

you need to replace it with a newer 

EPROM

.
