— 1 — — 2 — — 3 — MGate MB3180 Quick Installation Guide Third Edition, June 2008 1. Overview The MGate MB 3180 is a 1-port Modbus gateway that converts between Modbus TCP and Modbus ASCII/RTU protocols. It can be used to allow Ethernet masters to control serial slaves, or to allow serial masters to control Ethernet slaves. Up to 16 TCP masters and 31 serial slaves can be connected simultaneously. 2. Package Checklist Before installing the MGate MB 3180 Modbus gateway, verify that the package contains the following items: ? 1 MGate MB3180 Modbus gateway ? 4 stick-on pads ? Document & Software CD ? MGate MB 3180 Quick Installation Guide ? Product Warranty Statement ? Power adapter Optional Accessory ? DK-35A: DIN-rail mounting kit (35 mm) Notify your sales representative if any of the above items is missing or damaged. 3. Hardware Introduction As shown in the following figures, the MGate MB 3180 has one DB9 male port for transmitting serial data. weiV lenaP poTliaR-NIDeloh wercstnuomllaWeloh wercstrop laires 9BD elaMweiV lenaP tnorFtrop tenrehtE M001/01 54JRnottub teseR tupni rewoPweiV lenaP raeRdap no-kcitS Reset Button— The reset button is used to load factory defaults. Using a pointed object such as a straightened paper clip to hold the reset button down for five seconds. Release the reset button when the Ready LED stops blinking in order to load the factory defaults. LED Indicators—Three LED indicators are located on the top panel: Name Color Function On: Power is on and the unit is booting up Red Blinking: IP conflict exists, or DHCP or BOOTP server is not responding properly. On: Power is on and the unit is functioning normally Green Blinking: Unit has been found by the Location command in MGate Manager. Ready Off Power is off or power error condition exists Orange 10 Mbps Ethernet connection Green 100 Mbps Ethernet connection Link Off Ethernet cable is disconnected or has a short Orange Unit is receiving data from device. Green Unit is transmitting data to device. Tx/Rx Off No data is being exchanged with device. 4. Hardware Installation Procedure STEP 1: After unpacking the MGate MB 3180, connect the power adaptor. STEP 2: Use a standard straight-through Ethernet cable to connect the MGate MB 3180 to a network hub or switch. Use a cross-over Ethernet cable if you are connecting the gateway directly to a PC. STEP 3: Connect your device to the MGate MB3180’s serial port. STEP 4: Place or mount the MGate MB3180. The unit may be placed on a horizontal serface such as a desktop, mounted on a DIN-rail, or mounted on the wall.

When using termination resistors, it is important to set the pull high/low resistors correctly so that the electrical signal is not corrupted. Jumpers JP3 and JP4 are used to set the pull high/low resistor values for the serial port. To Set the pull high/low resistors to 150 K?, which is the factory default setting, leave the two jumpers open. To set the pull high/low resistors to 1 K?, use the jumper caps to short the two jumpers. MGate MB 3180 Jumpers 4PJ,3PJ 5. Software Installation To install MGate Manager, insert the MGate Document & Software CD into your PC’s CD-ROM drive. Locate and run the setup program, which will be named MGM_Setup_[Version]_Build_[DateTime].exe (e.g., MGM_Setup_Ver1.1.0_Build_07041910.exe) and follow the on-screen instructions.
