4.4.4 Program Message Descriptions
#
Purpose To allow the host PC to communicate with a device connected to the RPM4-E-DWT
COM2 port.
Classic
“#xx”
Arguments
xx:
The string to send out of the RPM4-E-DWT COM2 port. It must be less
than
40 characters long.
Remarks The RPM4-E-DWT COM2 port can be used to communicate to another RS232 device
(such as another RPM4-E-DWT). This allows the user to use a single COM port or
IEEE-488 port on the host computer to communicate with the RPM4-E-DWT and another
RS232 device. A carriage return and a line feed (
<CR><LF> ) are added to the string.
After this program message is issued, the RPM4-E-DWT will reply back every string
received by the RPM4-E-DWT COM2 port that is terminated with a carriage return. Line
feeds are discarded. This will discontinue when the next query is sent to the
RPM4-E-DWT.
There is no other reply from this program message. Prior to using this program message,
you must ensure that the RPM4-E-DWT COM2 port is correctly set up to communicate
with the device on COM2. Refer to the
“COM2=“ program message.
Example
(classic) Sent:
Reply: “#VER”
“DH INSTRUMENTS RPM4-E-DWT us A70M/A7M Ver1.00 ”
This example assumes that a second RPM4-E-DWT’s COM1 port is connected to the
RPM4-E-DWT COM2 port. This example gets the version of the second RPM4-E-DWT.
