3.2.6.1 Changing RR-24 Settings
The DIP switches are used to set the Modbus address and are also used to change the communication settings. Valid Modbus
addresses for RR-24 are from 1 to 192 where switch 1 is the least significant bit (LSB) and switch 8 is the most significant bit
(MSB). Address 254 is used to place the RR-24 in programming mode.
3.2.6.2 Programming Mode
When the RR-24 is powered with address set to 254, it enters programming mode. The STATUS LED will be flashing RED and
GREEN alternatively every 200 milliseconds to indicate that RR-24 is ready and waiting for the user to enter new communication
settings using 8 dip switches. Using the 8 dip switches, use can change the communication settings like baud rate and parity.
When looking at the switches with "Address" marking on top, the switches are defined from left to right.
• Switch 8, switch 7 and switch 6 are used to modify baud rate
• Switch 5 and switch 4 are used to modify parity
• Switch 1 is used to request to save the new settings
• Switch 3 and 2 are unused and should be left in ON position.

Set the switches to the desired value and then set switch 1 to ON and then OFF, and the new settings will be saved in EEPROM.
The result of saving operation is displayed on STATUS LED. Alternating GREEN/OFF every 200 milliseconds indicates saving new
settings passed and alternating RED/OFF every 200 milliseconds indicates that saving new settings failed. Once the new settings
have passed, disconnect power from the unit, set the address for the device using the address switches and apply power back to
unit.
3.2.7 Horn & Strobe Connection
There are four connection terminals for horns and strobes. The modular connectors are located at the top left of the board and
are labeled "Horn/Strobe".
Refer to Table 3 4 for recommended wire gauge vs. run length for the horn & strobe functions (maximum 2.5-volt drop in the
wire). The horn & strobe circuits are Class 2 control circuits, so Class 2 conductors should be used.
