USB to RS-232 Isolated TTL | CMOS 5ft. Adapter Cable w/ TB

Introduction:

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 RS-232 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.

USB to RS232 isolated TTL with voltage choices via DIP switch

The USB-2323TTLMOS-IS provides a USB to RS-232 port with 5V/3.3V/2.5V/1.8V TTL / CMOS compatible Logic levels. The RS-232 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.

Terminal Block Configuration:

Pin 1    TXD (Output)
Pin 2    RXD (Input)
Pin 3    VOUT (Output TTL / CMOS Power)
Pin 4    VIN (Input TTL / CMOS Power)
Pin 5    GND (Ground for TTL / CMOS)

Features:

• Provides 1 TTL/CMOS RS232 Serial Port over USB Port
• Supports 3-Signal TTL/CMOS RS-232 Conversion: (TXD, RXD, GND)
• The 2,500Vrms Isolation Model is Available
• Supports a 5-pin Terminal Blocks for TTL/COMS Signal Wiring
• 5V/3.3V Logic Level Selectable by DIP Switch
• Signal Levels are Similar to Standard RS232 but in TTL/CMOS Swing Level
• Supports 2,500Vrms Isolation for TTL/CMOS Signals
• Easy Serial Port Expansion over USB Port
• USB 1.1 and USB 2.0 Forward Compatible
• Built-in FTDI USB UART Chip
• Supports Serial Speed from 300bps to 921.6Kbps
• Supports 7,8 Data Bits
• Odd, Even, Mark, Space, None parity mode
