3.8 WRITING ALL OUTPUT LINES

All 16 possible output Lines may be set or cleared simultaneously with one command.

The desired level of each line [1=High(ON) 0=Low(OFF)] is represented by one bit in a

hexadecimal byte representing each four-line group. Refer to Section 3.10 for further

explanation of this compressed data format.

To set the level of all output lines with one command:

XOF (abcd) <CR>

O is the Output indicator

F is the Fast write indicator

a is the value for output lines 15-12

b is the value for output lines 11-08

c is the value for output lines 07-04

d is the value for output lines 03-00

Command :

XOF1111 <CR>
