BB-400 NeuronEdge Controller serial port configuration including RS-232, RS-422, RS-485 modes, hardware jumpers, and software settings

For many applications, a Bluetooth Adapter used in combination with another Bluetooth product (e.g. Brainboxes’ USB to Serial adapter connected to a PC with Brainboxes’ Bluetooth Software Suite, or a second adapter) essentially replaces the serial cable.

Brainboxes products use security enabled encryption.

RS-232 settings and cable wiring guide for Brainboxes ES light-industrial devices (ES-246, ES-257, ES-701, ES-279, ES-357, ES-020, ES-446, ES-457)

When the serial device is first installed, brainboxes' driver uses automated COM Port number assignment. The operating system has a COM number database, when driver is installed Windows OS will give the serial device the lowest free COM port number.

Brainboxes Bluetooth Adapters support the Serial Port Bluetooth Profile (SPP). Android allows communication with Bluetooth devices which have SPP.

The BB-400 features a fully configurable serial port, capable of being set to use any of the serial communication protocols ( RS232, RS422 and RS485 ). In addition to this, the serial port is also capable of accepting many of the most common baud rates, the minimum being 300 and the maximum 921,600.

Xon-Xoff is a flow control method used in communication between devices. It is in distinction to hardware flow control, which is done by specific out-of-band signals, such as DTR/DSR or RTS/CTS on the RS232 standard protocol.

This FAQ will explain how you can use Node-RED to send serial data from the BB-400 to the Cloud. This FAQ will assume you have a basic understanding of Node-RED so if you require further information regarding Node-RED please refer to the following FAQ.

A number of our customers are looking for a way to connect a serial port straight to the cloud securely. This FAQ will discuss the options available:

Full duplex mode uses 4 wires to transmit and receive data. Half duplex mode uses 2 wires to transmit and receive data and can only transmit or receive at any one time. To set an RS422/485 device into half duplex mode both the hardware and the drivers must be set correctly.

Linux support for the Brainboxes Ethernet-to-Serial (ES) range of devices

The only nodes required for this tutorial are:

The Brainboxes RS232 Adaptor (BL-510) is not a convertor, that is to say it does not have an on-board Bluetooth stack. The adaptor can be plugged into a PC's com port and then an application such as CSR's Bluechat can be used to open the port and perform enquiries and serial connections. This is useful for two RS232 devices where Bluechat can be used on both sides (Windows98, Windows2000 OS), but currently not applicable to any other type of device with an RS232 port. Details as to how to use Bluechat are in the Bluetooth section of the Technical Support page. 'Using CSR tools with Brainboxes products'. The Brainboxes RS232 Convertor (BL-521) is currently under development. It will have a Bluetooth stack up to RFCOMM and Serial Port profile embedded and running on the product itself. This means that it will send and receive standard serial data through the serial port. For this reason the device to which it is attached does not need to know anything about Bluetooth. Please monitor our website for details of the RS232 Convertor's release.

What is this FAQ for?

RS232 will reliably communicate up to 15 metres (~50 feet). It may be the case that with a well shielded cable in a noiseless environment greater distances can be achieved.

RS422/485 can reliably communicate up to 1.2 kilometres (~4000 feet).

Opening, closing & sending serial data on the BB-400

If the device connected to the BL-521 or BL-819/830 does not support RTS/CTS handshaking then problems can occur which are usually seen as the data only being communicated in one direction.

Check the following:

This FAQ explains which anti-virus programs may inhibit usage of your Brainbox device and which you may have to add exceptions for.

The cards mentioned above require later drivers to the standard released software version 5.4.1, as they were developed after the standard software was released. The drivers can be downloaded from the following location: Serial Solutions and are labelled as being specifically designed for these cards.

The Sony 9-Pin Protocol is a 2-way communications protocol for controlling advanced video recorders. Sony introduced the protocol to control reel-to-reel Type C Video Tape Recorders (VTR) and VideoCassette Recorders (VCR). It uses a DB-9 connector with 9 pins, where bidirectional communication takes places over a four wire cable, with accordance to the RS422 Standard.

A FIFO (First In First Out) is a type of buffer, where the first byte to arrive is the first to leave.

Brainboxes UARTA UART (Universal Asynchronous Receiver Transmitter) was one of the first really successful integrated circuits. It makes PC serial communications possible and all of Brainboxes Serial Devices (and almost all Bluetooth devices) contain a UART. In order to transmit data along a single wire it must be converted from its native parallel format (inside the PC) into a stream of 1's and 0's, and vice versa on the receive side.

When the gating of transmitter and receiver lines are controlled through software (using RTS) in a multitasking operating system, it can sometimes take too long for a transmitter to become a receiver because the transmitter can not set RTS false quick enough. This means that when the transmitter finishes transmitting data it can potentially lose part of the response because it is unable to become a receiver in time.

DTR/DSR Flow Control is a flow control method that is part of the RS232 standard. It uses two pins on the RS232 connector, DTR (Data Terminal Ready) and DSR (Data Set Ready). These two control lines allow the receiver and the transmitter to signal each other about their readiness to communicate.

A terminating resistor is simply a resistor placed at the ends of a cable. The value of the terminating resistor is ideally the same value as the characteristic impedance of the cable.

RS422 Standard

In the early days of serial communications buffered UARTS were not really necessary. This is because all operating systems were not multi-tasking, I.e. in DOS for example you did not edit text and communicate simultaneously.

Storage Temperature 8% to 95% non-condensing
