Dlc Wiring - Mantracourt DSC User Manual

DLC Wiring

Connecting wires are soldered directly to the pads on the top and/or bottom of the PCB. Care must be taken to
electrically insulate the connection pads from the surrounding metal.
The wiring on the load cell side should ideally be kept to less than 20 cm.

There MUST be a common connection from the PSU V- and the RS485 master's ground to ensure the RS485
stays within the required common mode voltage of +/-7 V.
The shield should be connected to the grounded enclosure of the power supply.
120 ohm termination resistors should be used at either end of the bus to stop reflections.
