Hardware Introduction

LED Indicators

or CHK_CFG will keep in steady red.
Off| PROFIBUS offline

The MGate 4101-MB-PBS and 4101I-MB-PBS both come with an RJ45 to DB9 cable for connecting to a serial console.

Reset Button

The reset button is used to load factory defaults. Use 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.

Pull-high, Pull-low, and Terminator for RS-485

Remove the MGate 4101-MB-PBS’s top cover to adjust the DIP switches for each serial port’s pull-high resistor, pull-low resistor, and terminator.

Hardware Installation Procedure

STEP 1:
Connect the power adapter. Make sure that the adapter is connected to an earthed socket. Connect the 12 to 48 VDC power line with the MGate 4101-MB-PBS /4101I-MB-PBS series’ terminal block, or connect the DIN rail power supply with the MGate 4101-MB-PBS/4101I-MB-PBS device’s terminal block.

STEP 2:
Use a PROFIBUS cable to connect the unit to a PROFIBUS PLC or other PROFIBUS master.

STEP 3:
Connect your device to the unit’s serial port.

STEP 4:
Attach the device to a DIN rail or the wall. The MGate 4101-MB-PBS/4101I-MB- PBS series is designed to be attached to a DIN rail or mounted on a wall. For DIN rail mounting, push down the spring and properly attach it to the DIN rail until it snaps into place. For wall mounting, install the wall mount kit (optional) first, and then screw the device onto the wall.

Wall or Cabinet Mounting

Mounting the MGate 4101-MB-PBS on to a wall requires two screws. The heads of the screws should be 5 to 7 mm in diameter, the shafts should be 3 to 4 mm in diameter, and the length of the screws should be more than 10.5 mm.
The following figure illustrates the two mounting options:
