1.1 Introduction
The UPS JBUS/MODBUS adapter (hereinafter referred to as “adapter”) allows you to use your host monitoring
software to monitor your Emerson UPS and FLP field lighting power supply system (FLP for short) equipment through JBUS/MODBUS (RTU) protocol, to learn about the equipment operating status by acquiring the equipment electrical parameter data, operating data and alarm data.
Currently the adapter supports the UPS and FLP equipment listed in Table 1-1.

Hardware description
The printed board of the adapter is available in two sizes: 130mm (L) ×60mm (W) ×1.6mm (H) and 130mm (L) ×63mm (W) ×1.6mm (H); additionally, the former has a narrow opening at the plug-in connector. The former is
applicable to NX, NXr series UPS and iTrust Adapt UPS, while the latter is applicable to Hipulse U series UPS, FLP, and all iTrust series UPS except for iTrust Adapt UPS.
As shown in Figure 1-1, the adapter provides communication port, equipment communication LED, host communication LED, plug-in connector and DIP switch, which are described in Table 1-2.

1. The adapter should be installed in the SNMP slot of the UPS or FLP, which is also used for the installation of SNMP card. Therefore, if you use the adapter, you cannot use the SNMP card.
2. The adapter is available in two sizes, please verify that your adapter matches the UPS or FLP (refer to the
hardware description in section 1.3). Otherwise, the adapter cannot be plugged in the SNMP slot of the UPS or FLP. 3. Some electronic components of the adapter are sensitive to static electricity. To prevent static electricity from damaging the adapter, do not touch its electronic components or circuits, also avoid their contact with live objects. Therefore, please hold the side edges of the adapter when moving or installing it.
2.3 Installation Procedures
Please install the adapter in the following sequence: 1. Set the basic parameters of the adapter; 2. Plug the adapter in the SNMP slot; 3. Connect the communication cable;
4. Set the communication parameters in the host software.
2.3.1 Setting Basic Parameters
To enable the functions of the adapter, you must set its basic parameters, which are: ?Physical address ?Communication baud rate
These parameters are set by the 8-bit DIP switch of the adapter (refer to Figure 1-1 for its location). The up position means ON, the down position means OFF, as shown in the following figure.
ON12345678 Figure 2-1 DIP switch
The basic parameters of the adapter are set by Bits 1~7 of the DIP switch, Bit 8 is factory reserved. The setting shown in Figure 2-1 is the factory default.

Setting physical address
The physical address of the adapter is set by Bits 1~5. The setting range is 1~31, 0 is factory-reserved setting, 1 is the factory default.
The physical address setting method is shown in Table 2-2:

Warning
The physical address 0 is factory reserved. You shall not set the physical address to 0; otherwise, the adapter cannot operate normally.
Setting communication baud rate
The communication baud rate of the adapter is set by Bits 6~7, and can be set to 2400bps, 4800bps, 9600bps, or 19200bps. 9600bps is the factory default.
The communication baud rate setting method is shown in Table 2-3:
