MGate MB3660 Modbus Gateway

Connecting to a Host or the Network
Two 10/100BaseT Ethernet ports are located on the gateway’s back panel. These ports are used to connect the
unit to a host or Ethernet network, as follows:
•
For normal operation, use a standard straight-through Ethernet cable to connect the unit to your Modbus
TCP network.
•
For initial configuration or for troubleshooting purposes, you may connect the unit directly to a PC.
The unit’s Link LED will light up to indicate a live Ethernet connection.
The MGate MB3660 has two Ethernet ports with two MAC addresses. Hence, the unit can be connected by two
different IP addresses.
Installing the Software
The Device Search Utility (DSU) can be installed from the Documentation and Software CD. Follow the
onscreen instructions after inserting the CD. For additional details, refer to
Chapter 3: Device Search Utility.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your MGate MB3660.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum allowed current for each wire size.
If the current goes over the allowed maximum, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be careful when handling the MGate MB3660. When plugged in, the MGate MB3660’s internal components
generate heat, and consequently the board may feel too hot to touch.
You should also observe the following common wiring rules:
•
Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the point of intersection.
NOTE
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference,
wires with different signal characteristics should be routed separately.
•
You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•
Keep input wiring and output wiring separate.
•
When necessary, we strongly advise labeling wiring to all devices in the system.
