RTU-MP Controller 9
Configuring the RTU-MP for N2
Refer to Appendix D of this document for the N2 Protocol Implementation Conformance Statement (PICS).
1
Turn off the RTU-MP's power.
NOTE Changes made to the switches when the RTU-MP is on will not take effect until the RTU-MP has
been power cycled!
2
Using the rotary switches, set a unique N2 slave address for the RTU-MP. Set the MSB ( SW1 ) switch to
the tens digit of the address, and set the LSB ( SW2 ) switch to the ones digit. Valid N2 slave addresses
are 01-99.
EXAMPLE To set the RTU-MP’s N2 slave address to 01, point the arrow on the MSB ( SW1 ) switch to 0
and the arrow on the LSB ( SW1 ) switch to 1.
3
Set the Comm Selector DIP switches DS1 and DS2 for the 9600 baud.
NOTE Use the same baud rate and communication settings for all controllers on the network segment.
TheRTU-MP is fixed at 9600 baud, 8 data bits, No Parity, and 1 Stop bit.
4
Set SW3 Comm Selector DIP switches DS3 through DS6 for N2. See example below.
5
Leave DS7 and DS8 in the OFF position. These switches are not applicable to N2.
