TEST MESSAGE: “TM[CR]”
The test message is primarily a diagnostic aid. When the test message command is
received the unit will respond by outputting information particular to the model num-
ber and software version/revision.
CONTINUOUS READING: “CR XXXX[CR]”
The continuous reading command allows setting of the automatic update feature of the
DP-7600.
X = -1 - readings are transmitted 20 times per second
X = 0 - automatic updates disabled
XXXX = 1 - 3600 -number of seconds between updates
SET LEGEND: “LR X[CR]”
The set legend command allows a unit indicator to be attached to readings transmitted
by the unit.
X = ? legend number (from table) for reading units
REMOTE SERIAL COMMAND: “SC X YY[CR]”
In data logging applications, involving several units daisy-chained together, a problem
arises when it is desired to have several units automatically transmit readings at the
same time interval (since contention could result in scrambled data at the printer). To
compensate for this, the model DP-7600 allows unit to “take turns” on the same serial
bus. This is done by enabling transmission of a special non-printable character at the
end of a reading string; which, when received by the following unit will cause it to
execute a serial command (RD would be most common). The second unit can have
the device code enabled and so on. Note: all units should have the echo function
enable so that messages will pass along to the following units in the chain.
DECIMAL POSITION: “DP X[CR]”
The display decimal point can be positioned using this command.
X = 0 88888 (no decimal point)
X = 1 8888.8
X = 2 888.88
X = 3 88.888
X = 4 8.8888
X = 5 .88888
