Values The Value may be sent as text or as a value number. In this column, some values have no

text, such as the command

auto.level.status. This command takes a value of

0 through 4, not “idle” or “working with black”, etc. It replies with the same numerals,

never words.

Text values can be sent in upper or lower case or with mixed case. They are listed in

UPPER CASE in the table to make it easier to see the difference between the value and

any [explanation].

[varies] means the range of acceptable values and replies varies with the type of source.

Reading the Response Two commands establish the features of the replies. (Remember the displays only reply

when individually addressed.)

ascii.eol determines the End Of Line character the display will send at the end of

every command.

ascii.response determines how you want the replies to look when they come

back to you.

• Symbolic means the replies will come back as ascii characters, if the value column

allows them.

• Numeric means that the Value Number will come back

• Data means that only the value is returned, not the preceding information

The following table shows examples of each setting for ascii.response and three

possible responses:

[none] Execute means the

command is

executed. No

character fol

lows the com-

mand (or the

Target, if it has

one)

op 04 lamp.hours.reset [CR]

Resets the lamp hours meter

for the Lamp in unit 04.
