USB to RS232 Isolated TTL | CMOS Adapter Cable with TB
$43.95
The new USB to RS232 isolated TTL adapter allows you to control your voltage setting as you need whether 3.3V or 5V is needed. Dip switch controls are located at the RS232 terminal block for easy access to your voltage setting.
Up until now you’ve had to make a choice between USB to TTL adapters and their voltage with either or selections. This USB to RS232 isolated TTL/CMOS adapter cable eliminates that by allowing you to choose a voltage setting right at the adapter’s connection point at the terminal block. If there is no need for isolation in your application, this adapter is also available in a non-isolated version.
The USB-2323TTLMOS-IS provides a USB to RS232 port with 5V/3.3V/2.5V/1.8V TTL / CMOS compatible Logic levels. The RS232 signals include TXD, RXD, and GND with 2,500Vrms Isolation on each signal. The RS232 TTL cable is USB bus powered and does not need any DC power from an external AC Power Adapter. The TTL /CMOS RS232 signals are processed on the 5-pin Terminal Block.
