EasySYNC Unveils Its Latest High Performance Single Port USB-to-Serial Adapters

EasySYNC Ltd, a specialist in USB communications, has further strengthened its range of USB-to-RS422/RS485 adapters with the introduction of two brand new products which are not only highly cost effective but also extremely convenient to use. The ES-U-2001-S is a single port adapter which allows plug-and-play installation. Automatic transmit and receive control is incorporated for its 2-wire RS485 half-duplex mode. It is complimented by the ES-U-2001-STB adapter, which has the same features and functionality, but with a 5-pin terminal block connector included which facilitates the wiring process.

Suitable for connection with either USB 1.1 or 2.0 hosts, these adapters’ high speed serial ports are capable of dealing with data rates from 300kbit/s right up to 921.6kbit/s, with non-standard data rates supported. They both have built-in termination and biasing mechanisms. Their construction is such that opening of the chassis to set the RS422/RS485 operation modes can be avoided. Instead the upper panel can be slid open in order to gain access. The serial port on each adapter has electro-static discharge protection to a voltage of 10kV. LED indicators are incorporated - allowing the simple monitoring of the transmitter and receiver functions as well as the power source connection.

Both of these new EasySYNC adapters support Windows 8, Windows 7, Windows Vista, Windows 2003, Windows XP, Windows 2000 and Linux operating systems. They are compliant with EN55022 Class B, EN55024, EN61000-3 and IEC 61000-4 standards. An operational temperature range of 0°C to 55°C is covered. The pricing for the ES-U-2001-S is $58.00, while pricing for the ES-U-2001-STB is $56.98 for single units.
