For RS-485 or communication connection it is recommended to always use a twisted wire to reduce noise and allow for reliable
data communication over greater distances. For best performance use shielded 3-conductor wire with one twisted pair
providing a pair for signal (A & B), common (COM) and shield ground (SHD) connection.
NOTE: Running the RS-485 cable adjacent to or in the same conduit with high voltage wires is not recommended as there may
be interference from the high voltages.
RR-24 provide integral termination for end of line resistors (EOL). The termination uses 4-pin connector (labeled J8) to select
termination. Place the EOL jumper on one of the following positions:
• NU = No termination (default)
• 120 = 120 Ohm
• 100 = 100 Ohm

3.2.6 Remote Relay Operation
Power LED will light up green to indicate the unit is operational. TX LED will flash blue to indicate the unit is communicating with
DVP-1200. RELAY 1 and RELAY 2 LED will light up red when corresponding relay is activated. Refer to Figure above for location
of Relay 1 and Relay 2.
