USB-powered multiport serial modules

14 October 2009 Telecoms, Datacoms, Wireless, IoT

FTDI has announced the availability of multiport variants of its USB-powered USB-COM-PLUS family of communication modules. Complementing the previously released single-port USB-COM232-PLUS1 module, these new modules are available in RS232 (EIA-232), RS422 (EIA-422) and RS485 (EIA-485) versions. The USB-COM232 modules provide either dual- or quad-port options. The USB-COM422 and USB-COM485 modules provide dual-port capability for the RS422 differential and RS485 multipoint differential interfaces. Single-port versions of these interface modules are also available.

All multiport modules feature a USB 2.0 Hi-Speed (480 Mbps) interface and are powered from the USB port, saving the need for an additional external power adapter and associated costs. PCB-mounted LEDs provide indication of USB enumeration, RxD and TxD signals. The complete USB protocol and all level shifting is handled by the modules without the need for any application software modifications. In addition, royalty-free WHQL approved drivers are available for all popular operating system platforms, further aiding installation and deployment.

The USB-COM485 family also feature a +5 V output that can provide up to 250 mA. This can be used to supply the interface logic of customer-attached equipment. The dual- and quad-port modules utilise FTDI’s FT2232H and FT4232H ICs. These 480 Mbps USB 2.0 Hi-Speed devices are configured as asynchronous serial interfaces together with an appropriate level shifter circuit.

The whole range of modules can operate from -40°C to +85°C and are CE/FCC approved.
