EPT 232R-US-R1 USB to Serial 1 meter cable


The TRX-1226 USB to Serial cable
Virtual COM Port
Premium Quality, Gold PLated Connectors, Tough Rubber Exterior


The TRX-1226 USB to Serial cable is a complete solution in adapting legacy serial devices with RS232 interfaces to modern USB ports. Each TRX-1226 adapter contains a small internal electronic circuit board which utilises the FTDI FT232R chip, mounted inside a rugged plastic enclosure capable of withstanding industrial temperature ranges.


The Cable incorporates a standard USB-A device connector for connection to an upstream host or hub port. RS232-level signals, including modem handshake signals, are available on an industry-standard DB-9 Male connector. The maximum RS232-level data rate is 0.5 MBaud. The TRX-1226 adapter cable requires USB device drivers, available from www.earthpeopletechnology.com/resources/drivers, which are used to make the EPT 232R-US-R2 appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperSerialPort, to exchange data through the TRX-1226 to a legacy RS232 peripheral device.
