Global or addressed time set command. No message is returned from the REMOTE in response to a
global TM command, but it will respond with an OK to an addressed TM command. Time is in 24 hour
format. This command is useful for synchronizing multiple ZENO
®
-3200 units.
EXAMPLE of Global Command: #TM94100212000056(ETX)
Set Date and Time to October 2, 1994, 12:00:00 PM. (ETX) represents 0x03 character.
EXAMPLE of Addressed Command:
HOST: #01340001TM95101009050060 (ETX)
REMOTE: #00010134
OK,14(ETX)
The HOST addresses a command to the REMOTE, setting the station date and time to October 10, 1995,
9:05 a.m. The REMOTE acknowledges the command.
4. DATA RETRIEVAL COMMANDS
D*
Request all data sets residing in the REMOTE’s data logging memory. This command behaves similarly
to option * in the Data Retrieval Menu.
377
Caution should be considered before using this command as it
may require several minutes of data transfer time if there are numerous data sets stored in the REMOTE’s
logging memory.
EXAMPLE: #01340001D*03(ETX)
To ID 0134 from 0001, send all data sets in logging memory.
D@nn,
Request nn unmarked or oldest data sets. This command behaves similarly to options @ and M in the Data
Retrieval Menu.
378
These are data sets which have not been acknowledged by the HOST as having been
received. The value of nn can be any positive integer from 1 to 9999, or the asterisk character. The nn
parameter must be comma delimited to separate it from the checksum. If the requested number of data
sets is larger than the actual number of sets in logging memory, the REMOTE will send all data sets in
logging memory followed by an EOF string. The HOST station should acknowledge the receipt of valid
data set messages with a CCSAIL OK message. This indicates to the REMOTE to mark the previously
transmitted data sets as having been sent. The REMOTE will then respond to the next D@nn command
by sending data sets logged after the last marked set. If the received message from the REMOTE fails the
proper format check, then the requesting station ignores the received message, and sends the request
command again.
EXAMPLE: #01340001D@*,11(ETX)
