3.2 ACS/BMS II/BMS Wiring Connections to ProtoNode RER and LER
• When an ACS, BMS II, or BMS is being used, an RS-485-to-RS-232 converter will be required to
connect it to the ProtoNode’s RS485 port (green 6-pin Phoenix connector).
• Refer to Figures 5 and 6 to locate the internal RS-232 connector JP12 (BMS) or JP5 (BMS II/ACS) inside
the wiring area of the ACS/BMS II/BMS.
• If the AERCO RS232-to-RS485 Converter (part no. 124943) is used, the RS-232 side of the converter
contains a connector that plugs directly into header connector JP12 (BMS) or JP5 (BMS II/ACS).
• If a third party converter is used, connect the RS-232 Receive (RxD) and Transmit (TxD) wire leads to
the internal RS-232 connector (JP12 or JP5) as shown in Figures 5 and 6. DO NOT connect the wire
shield on this side of the converter.
NOTE
If a third-party RS232-to-RS485 Converter is used, consult the manufacturer’s instruction manual for signal
polarity.
• On the RS-485 side of the converter (Figure 5 to Figure 7), connect the wire leads as follows:
o Connect the TD B (+) terminal to the ProtoNode’s RS485+ Port.
o Connect the TD A (-) terminal to the ProtoNode’s RS485- Port.
o Connect the GND terminal to the ProtoNode’s RS485 Frame GND Port.
