1. Introduction
Modbus is an industry adopted communication protocol based on RTU, ASCII, and TCP protocols for
various applications; these three protocols are commonly used by hardware equipments in the industry,
such as DCS, PLC, HMI, power load measurement, various sensor and measuring instruments. The
Modbus Gateway is capable of implementing the Modbus environment between different hardware
interfaces, thereby streamlining the process of management and application.
Diverse Hardware Infrastructure
Modbus Gateway supports the four most commonly used hardware communication interfaces, RS232,
RS485, RS422, and Ethernet. The simple-to-use configuration software provided with Modbus Gateway
can quickly modify the hardware interface to use, and easily switch to the existing hardware
communication infrastructure.
Switching between Modbus Protocols
Modbus Gateway supports the standard Modbus protocol and is capable of converting any Modbus
protocols between Modbus TCP and Modbus RTU or Modbus ASCII for all supported hardware
interfaces.

2.2 Installation Procedures
Step 1: Connect MB5001C to power source using 5V DC Jack(Note that DC Jack is 5V only, and only
use it with a power adaptor), or 9~30V DC Terminal Block power source.
Note：MB5001C provide two power inputs can be connected simultaneously to live DC
power sources. Anyone of the power inputs fails, the other live source acts as a backup
to support power needs automatically. The redundant dual DC power inputs give one
extra assurance of non-stop operation.
MB5001C : 5V DC Jack or DC 9-30V 3-pin Terminal Block power input
MB5001C-Sis: DC 9-30V 3-pin Terminal Block power input
Step 2: Connect MB5001C to Ethernet network. Use a standard straight-through Ethernet cable when
one connect it to a hub/switch, one also can connect it to ones PC„s Ethernet port via a
cross-over Ethernet cable for easy set up. However, in this case one need to make sure ones
PC is in the same network sub-net as MB5001C.
Step 3: Connect MB5001C‟s serial port to a serial device.
Step 4: Placement options. One can mount MB5001C to a wall/panel (Mounting screws included) or
Din-Rail rack (Require optional item model: Din-Rail-Kit DK-25).
