Additionally, the serial port are 2.5kV electrically isolated (ISO-version only), making it ideal for deployment in hazardous industrial environments. The USB-COM Plus Mini is fully ESD and surge protected at the USB and serial port interfaces. 500kbps) can easily be set up in the range of up to 960 kbps. USB 2.0 full speed connection allows serial data rates of up to 3Mbps for RS422/485 and 921.6kbps for RS232. A configuration tool allows easy access to special Windows driver options. High/Low biasing resistors are not needed as such, hassle-free usage is guaranteed for the user.Ĭom Port drivers are available for Windows, Linux and Mac OS X. The differential line termination for RS485 (120Ω) is automatically controlled by choosing the appropriate operating mode. The serial port allows different operating modes - which are easily configured using the bottom DIP switch - to fully support RS232, RS422 and RS485 protocols. Lastly, both DIN-Rail and wall-mounting options are available. The ISO version is 2.5kV electrically isolated to withstand unbalanced ground loops that arise in hazardous industrial environment. Furthermore, it can operate across a large range of temperature levels to cope with harsh operating conditions. The device is fully ESD and surge protected, bus powered and accommodated in a tiny metal case. It Allows portable devices (such as cell phones which support OTG) to connect directly to other devices such as USB keyboards, mice and mass-storage devices.All current OTG devices are required to have Micro-AB receptacle usb connector usually marked as 'host aor some symbol.USB-COM Plus Mini provides easy serial port expansion over USB 2.0 connecting to high speed RS232 or RS422/485 devices. USB On-The-Go (OTG) introduces the concept of a device performing both master and slave roles. Power Delivered by Micro-USB 2.0 must not exceed 3A / 20 V (60 W), usually 2A/5V charger is used. Most devices can receive power in host mode, even though this is not part of the standard. Additional Pseudo-standards added by some device manufacturers: If there is no-connect on the data pins, the device will assume it is connected to a charging only cable. Low (small value resistor to ground or connection to ground) if you are connecting an accessory that the device must ask as a host for. The device with the 5-pin connector has a pullup to high on the connector. Table 1 provides the pinout information of the Mini-USB Type-B console port. The default baud rate for the console port is 9600 baud. There are two variants of plugs: Micro-A connector and Micro-B connector and two variants of receptacles - Micro-AB (for both Micro-A and Micro-B connectors) and Micro-B. The Mini-USB Type-B console port uses a Mini-USB Type-B connector to connect to a console management device. Micro-USB connectors, which were announced in 2007 have a similar width to Mini-USB, but approximately half the thickness, enabling their integration into thinner portable devices. See also newer Micro-USB 3.0 cable pinout. Contrary to popular belief, D+ and D- operate together they are not separate simplex connections. Half-duplex differential signaling helps to combat the effects of electromagnetic noise on longer lines. In USB data cable Data+ and Data- signals are transmitted on a twisted pair. NRZI (Non Return to Zero Invert) encoding scheme used to send data with a sync field to synchronise the host and receiver clocks. Micro-USB cable uses 4 shielded wires: two for power (+5v & GND), two for differential data signals (labelled as D+ and D- in pinout). May be N/C, GND or used as an attached device presence indicator (shorted to GND with resistor) The micro-USB connector is often used for portable devices charging (with micro-usb charging cable) or mobile devices data transfer (with micro-usb data cable). Nowdays Micro-USB competes with newer USB type C and Micro-USB 3.0.
