Foreword

The Remote Backlight Controller (RBC) module is a part of the MTe monitor series and of the EPC C2D Nautic series. The main purpose of this module is to enable remote access to some of the monitor parameters or features, especially the backlight.

Supported features are dependant on the device with the built-in RBC module. Dimming can be carried out using the buttonson the front, or remotelyby

interpreting SCOM commands received from the RS232, RS485 or USB interface. The internal ﬁrmware manages all software tasks includingthe SCOM command handling.

This manual describes the features, the conﬁguration and the usage of the RBC module.

Note:

The different pins of COM A and COM B are hard–wired to each other. This means that using both interfaces at the same time is only allowed in RS485 mode. In RS232 mode only one interface can be used.

Note:

In RS485 mode the switchingfrom receiving to transmitting and back must be performed very fast (typical 20 µs). NotallCOM ports or adapters support such a speed. Make sure that the hardware used is fast enough.

1.1.2 Buzzer In/Out Pin Conﬁguration

There is a buzzer integrated in the front behind the front foil. Itcan be turned on or off by a SCOM compatible RBC software command.

It can also be activated by the buzzer-in hardware input according to the following table.

The resulting buzzer-in signal is evaluated by an OR operation on the signals from software and hardware.

Buzzer-out is a relay contact parallel to the integrated buzzer that can be used to switch an external signal device.

The buzzer-in and -out can be connected to the 4-pole Phoenix connector:

1.1.3 Power Remote Pin C onﬁ guration

Remote power out is a relay contact that is closed after the power button on the front side is pressed for more than one second. Itis opened after the button is released. Withthe remote power out signal, it is possible to switch an external Beijer Electronics EPC Nautic on and off. TheEPC hasa corresponding ATX power remote input. To use this function, connectthe double-pole Phoenix connector to the corresponding connector on the EPC.

1.1.4 USB Interface

TheUSBinterfaceoftheRBCmodulecannotbeaccesseddirectlybyaplug. In an EPC, the USB interface is built-in and internally connected to the USB root

hub of the PC. This means that if the PC is running, the USB interface is always accessible.

In an external MTe monitor,the USB interface is accessible if the monitor is connected to the PC by a USB cable. Indetail a 4-PortUSB 2.0 hub is accessible to which the RBC module and other monitor components are connected.

If an MTe XXX E (Ethernet) is connected by an Ethernetcable to a PC, the RBC is accessible as a USB device too, because a virtual USB connection exists using the Ethernet hardware.

1.2 DIP Switches

The DIP switches can be used to adjust the mode of the serial interfaces as well as the monitor address.

The four DIP switches that areused to set addresses entails setting 16 binary addresses (0–15) This makes it possible to connect up to 16 monitor for example via the RS485 interface. It is possible to ignore the DIP switch settings; instead using software settings for address and serial mode and assigning up to 240 different monitor addresses in 15 different groups.

With the default setting, all DIP switches are OFF, which means that the monitor is set with address 0 in RS232 mode.

1.2.1 Accessing theDIP Switches

TheDIPswitchesareplacedontheRBCmodule,thatisabuilt-inpartofanEPC C2D Nautic or an MTe monitor.

MTe Monitor DIPSwitches

The DIP switches onthe MTe Monitor are located next to the COM ports and are available from the outside of the device.

EPC C2D Nautic DIP Switches

To access the DIP switches that are located on the RBC module of the EPC C2D Nautic,the housing has to be opened according to the steps below.

Note:

Inside the EPC there are electronic components which can be destroyed by electrostatic charges. Therefore cautionary measures have to be taken from the moment the EPC is opened. These can be found in the guidelines for electrostatic endangered components (EGB-guidelines).

Disconnect the EPC from the powersupply.

Warning:

Make sure that your electrostatic p ad does not damage the front panel of the EPC.

Loosen the screws of the left part of the back cover(the partwith the fan) using a 2.0 mm Allen key.

After removing the screws, the enclosure can be easily opened. Be careful with the cables connected to the fan.

Locate the DIP switches on the RBC module, positionedat the opposite side from the communication ports.
