Industrial / Non-Isolated
Industrial Port-Powered RS232 to TTL 5V Converter
The TTL-232-1 is a compact, industrial-grade, port-powered RS-232 to TTL converter, which can be used to convert RS-232 to 5V TTL / CMOS compatible levels and vice versa. The unit is efficiently powered from the RS-232 data line, and it comes with the auto-sensing and self-adjusting features, which automatically adjust baud rate, parity, stop bit and other COM port parameters to the devices that they are connected to. Therefore, it requires no external power or software drivers, making the unit a highly reliable and truly plug-and-play device.

The TTL-485-2 is a compact, industrial-grade RS485 to TTL converter, which can be used to convert 2-wire RS485 to 5V TTL / CMOS compatible levels and vice versa. The unit is powered from an external 5V DC regulated power supply (included); it supports data direction auto-turnaround, which automatically enables the RS485 transceiver when data is present on the TTL side. Therefore, it requires no software drivers or flow control, making the unit a highly reliable and truly plug-and-play device. The built-in selectable 120-Ohm terminator can be turned ON or OFF through a simple jumper setting, thus making the unit an ideal solution for all types of applications.
