SERVICE BITS BCD
Number in BCD code in the range 0 to 80
All values are read at the 0 1 variation of the synchronism signal SY. Each time, after entering a variable, the
indicator (CURSOR) for laying the next variable is automatically increased by one position (if not otherwise
commanded).
The 4 Service Bits can be used to enter an OFFSET (value 0 to 13) that the display unit will add to the variable
cursor position to lay the variable. In this case, the actual cursor stays in its initial position and increases by 1
relative to that position.
2.4.4. Command TYPE 5: Variable in ASCII code
Inputs SY D C B A
Command TYPE 5 IMP 0 1 0 1
This coding identifies the presence of a variable ASCII-coded character in the first 9 inputs.

ASCII character in the range 20H to 7F
Values are taken at the 0 1 variation of the synchronism signal SY. The position cursor is automatically
increased by one position each time.
2.5. SERVICE COMMANDS
2.5.1. Command TYPE 7: " Manual " operation and associated commands
Inputs SY D C B A
Command TYPE 7 0 0 1 1 1
This command enables using the first 9 inputs in a " MANUAL " mode for device checking purposes.
Functions accomplished by the inputs are as follows:
