Section 3 Command Descriptions

3.10

Data received for output to the digital ports must be contained within a

prefix (

) and a suffix (

) and each 4-bit quantity must be separated by

semicolons. Leading zeros are not required. If the amount of data sent is less

than the number of bits programmed as outputs, the least-significant bits will

contain the data sent and the most-significant bits will be cleared to logic zero.

If the data sent is greater than the number of bits programmed for output or

selected by the

command, the

Digital232

will generate a conflict error and

ignore the entire command string. The

Data Strobe

output is pulse for

approximately 50 microseconds after new data is output on the selected port(s).

Example:

select ASCII/binary mode

read data from the

Digital232

display shows

0001;1111;1111;0001

D1111;0;1010;0101Z

read data from the

display shows 1111;0000;1010;0101

F3 Format - ASCII Decimal

In the

format, the data is described in decimal 8 bit multiples and

transmitted in ASCII. Each decimal number (0 to 255) to be output must be

separated by semicolons.
