System Wiring

Warning: Remove power from all devices
before connecting or removing the
DS12R.
Connect devices as shown in Figure 4. If the DS12R is
the last device on the RS-485 bus, connect a 120 Ω
end-of-line (EOL) resistor in parallel with the
RS-485.
Only the last device on the RS-485 bus
requires a 120 Ω EOL resistor (included
with the MTGW CAN-RS-485 BUS
Gateway).
