The PD24 converter is a device designed to transfer data between a computer and a device equipped with an RS-232 interface with TTL voltage levels. The converter provides standard transmission speeds up to 115.2 kb/s, where the speed depends on the length of the cables used. • 1.5 m data transmission cable with RJ12 plugs 1 pc • computer with an USB 2.0 port • operating system: Windows 2000/XP/VISTA/7/8/8.1/10/11 or Windows Server 2003/2008/2012/2016/2019/2022 - 32/64bit The converter is a portable device powered from two sources: from the computer’s USB bus and from a device connected via the...
