High resolution CRT (MZ1D02. MZ1D03)

Medium resolution CRT (MZ1D01, MZ1D06)

A period is output for a decimal point

A comma is outputted for a decimal point

Low state or open ER signal during data output will result in anerror

The signal ER becomes invalid

CD is high as long as power is on to the main unit

CD goes high only during data output However, it would not go high if the echo back function is on the host side

An error is cause when the PO signal is high during data output

Polarity is inverted for the above

Normally in capital letter, but in small letter when shifted

Normally small leter and in capital letter when shifted

3500 CG will be assigned when the 200 raster CRT is in use

2000 CG will be assigned when the 200 raster CRT is in use

Dip switches (A) and (B) located on the PWB are used for servicing the MFD or for other machine service and there fore the user is not supposed to use these switches In addition, these switch must be used when either the CE 330M or 331M is used as the expansion MFD
