## Summary description

The EXSYS EX-1309-T is a 1.8 m long black serial cable featuring a USB Type-A connector. Weighing 160 g, it offers reliable connectivity for various devices. Ideal for data transfer and communication, this cable ensures stable performance and durability, making it a practical choice for both personal and professional use.

## Long description

The EXSYS EX-1309-T is a 1.8 m black USB Type-A to RS-232/422/485 serial cable that adds a single high-performance 16C550-type UART compatible RS-232 serial port to a PC, thin client, notebook or server via a USB 1.1/2.0 port. The cable supports multiple serial standards over a 5-pin terminal block and draws power from the USB bus, with optional power via a DB9 connector. It is a plug-and-play solution that provides instant COM port expansion without opening the computer.
Advantages
The cable supports RS-232 (V.24), RS-422 and RS-485 interfaces in one compact solution, providing flexibility for different serial devices. The built-in 16C550 FIFO with 16-byte buffer improves data handling and reduces CPU load. USB bus power eliminates the need for an external power adapter in typical setups, and optional features such as DB9 power support and an installable DIN-rail kit (EX-6099) offer additional installation versatility for rack or industrial environments.
Suitable for
Adding a COM port to desktops, notebooks and thin clients via USB Type-A
Connecting equipment using RS-232 serial signaling (TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND)
Connecting RS-422 full-duplex devices (4-wire: TX+/-, RX+/-)
Connecting RS-485 devices in half-duplex or full-duplex configurations (2-wire or 4-wire)

How to use
Connect the USB Type-A plug to an available USB 1.1 or 2.0 port on the host computer. Terminate the device side to the appropriate pins on the 5-pin terminal block according to the required interface (RS-232, RS-422 or RS-485) and wiring scheme. Install drivers if the host operating system does not automatically recognize the USB-to-serial adapter; after driver installation the cable appears as a COM port and can be used by serial communication software without opening the computer chassis.
Usage recommendations
For stable serial communication, verify correct wiring and ground connections for RS-232/422/485 devices, select matching serial parameters (baud rate, data bits, parity, stop bits) in the host application, and use the optional DB9 power only if specifically required by the connected equipment. For rack or industrial installations consider the EX-6099 DIN-rail kit.
