Omega DP-7600, Руководство пользователя

Страница: 14 / 31

Each DP-7600 command consists of two upper-case alpha ASCII characters. In most
instances, commands can be sent to the unit with a numeric value (ASCII format)
attached for parameter setting. When the unit receives and executes a valid command
it responds by transmitting “ok[CR]”. Commands can also be sent to the unit without
a parameter attached to interegate the current setting for the parameter associated with
that command. In this instance, the unit responds with the equivalent lower-case char-
acters for that particular command along with an ASCII representation for the numeric
value of the parameter in question. The following is an example of a possible exchange
sequence between a model DP-7600 and a host computer:
Exchange 1: HOST SENDS : “AE0[CR]”
DP-7600 RESPONDS WITH : “HELLO ae 0[CR]”
(Note: The unit address is assumed to be set a zero.)
Exchange 2: HOST SENDS : “RD[CR]”
DP-7600 RESPONDS WITH : “99.99lbs[CR]”
(Note: It is assumed the display reading is 99.99 and that the legend is set for lbs.)
Exchange 3 HOST SENDS : “S1 1000[CR]”
DP-7600 RESPONDS WITH : “ok[CR]”
Exchange 4 HOST SENDS : “S1[CR]”
DP-7600 RESPONDS WITH` : “11 1000[CR]”
Exchange 5 HOST SENDS : “AD0[CR]”
DP-7600 RESPONDS WITH : “BYE ad 0[CR]”
Note: Remember [CR] represents a carriage return character.
The following is a list of the serial commands available on the DP-7600. Each com-
mand string is shown in quotes, a parameter/number field is represented by X (first) or
Y (second), the sign, where needed, is shown as a lower case s(s). A brief description is
given for each command along with any particular programming instructions.
ECHO: “EH X[CR]”
The echo command allows enabling or disabling of the unit’s echo feature. When the
echo feature is turned on the unit automatically echo’s all received characters.
X = 1 echo ON
X = 0 echo OFF
