Programming with MR
Protocol
The RLPC can be programmed using the MR Protocol. The full
protocol is detailed in
Appendix A: “MR Protocol Commands” on
page A-1 .
This protocol allows the instrument to be controlled remotely by a third
party application or terminal program, such as ProCOMM or Windows
Hyper Terminal and is compatible with Met One particle counters.
Note:
Multiple alarming
is disabled by MR Protocol.
This chapter provides the information needed to program the basic
configuration for the instrument using the MR protocol.
DIP Switches
With other protocols, the instrument Location is independent of the
Device Address. When using the MR Protocol, however, Location and
Device Addresses are the same.
In its default configuration, the counter reads its DIP switches during
power-up and reset.
To use DIP switches 1-6 for Location/Address, move Switch #7 and #8
to the ON position.
Note:
When changing
the DIP switch settings, the
instrument power must be
cycled off and on.
To configure the Location/Address using a software command, move
switch #7 to the ON position and switch #8 to the OFF position.
Protocol
Settings
The MR Protocol is defined through an RS485 interface with:
• Baud Rate: 9600
• Data Bits: 8
• Stop Bits: 1
• Parity: None
• Flow Control: None
Power On
When first powering up the instrument, if no commands are sent to the
unit within 60 seconds, then it will begin sampling using the default
configuration:
