If you use the RAMTEST command you will have to wait a
minimum of 6 seconds for it to complete before you try to execute
another P113.
Some Dataloggers do not support P65 Bulk Load. In that case you would have to
use a P30 Instruction for each ASCII character.
5.2.15 Command 1024: Send String to Device
This command requests the SDM-SIO4 to transmit a user-defined text string
(entered in the command line mode) number 0..255 or a fixed string 256..511. The
string number is defined in parameter 5. The string is transmitted from the
specified port to the RS232 device. If the specified string has not been allocated
then ‘
string not allocated ’ is transmitted.
Values per repetition = 0
Minimum delay = characters*0.26*ports in milliseconds
5.2.16 Command 1025: Transmit a Byte
This command transmits a byte (defined in parameter 5) from the SDM-SIO4 to
the RS232 device. The byte must be in the range of 0..255 for binary code.
Values per repetition = 0
5.2.17 Command 1026: Serial Port Status
This command requests the SDM-SIO4 to send the current output level of status
lines, number of framing errors, number of parity errors and number of overruns.
This is sent to the datalogger as four Campbell Scientific floating point numbers
to consecutive input locations.
Values per repetition = 4
First Value Returned
