Industrial RS232 to 5V TTL Converter

Model TTL-232-5IE

Category: RS232 / RS485 to TTL Converters

DESCRIPTION

The TTL-232-5IE is an industrial grade bi-directional port powered or external powered RS232 to 5V TTL converter which converts a full-duplex RS232 port to a 5V TTL signal. A built-in data direction auto-turnaround feature automatically enables the TTL driver when data is present from the RS232 port, eliminating the need for software drivers, and making the device fully plug-and-play. The TTL-232-5IE has a DB9 female connector on the RS232 serial port, and DB9 male connector on the TTL port. A separate terminal block is included with the product. The terminal blocks plugs into the TTL port, providing screw-lug wire terminations for the port. The unit is enclosed in a rugged ABS housing, and is powered from the RS232 data lines or optional 5V external power input. This converter operates from 300 to 115,200 bps.

PORT POWERED WITH OPTIONAL EXTERNAL POWER:

The TTL-232-5IE has an optional 5V DC external power input, The TTL-232-5IE is normally port-powered from the RS232 data lines while using a capacitor charge pump built into the converter to provide necessary power. There are rare instances where the RS232 host device is not capable of port-powering the converter due to signal incompatibilities or low voltage levels. If this should occur, all that is necessary is adding a 5V DC external power to the terminal block or DB9 connector. Because the TTL-232-5IE is industrial grade and port-powered with an optional 5V power input it makes this converter versatile.

Using one TTL-232-5IE unit:

  1. Check that all connections comply with the connection diagrams.
  2. Perform a loop back test on one unit:
    1. Connect the IN to OUT on the TTL port.
    2. Connect the RS-232 port to the PC RS-232 port.
    3. Running a hyper terminal program on the PC, send ASCII characters to the TTL-232-5IE converter from one PC port, and check that the characters are received at the same PC port. This tests that the transmit and receive functions of the TTL-232-5IE unit is working properly.

Using two TTL-232-5IE units:

  1. Check that all connections comply with the connection diagrams.
  2. Perform a loop back test on two units:
    1. Connect the two TTL ports. Connect OUT to IN and IN to OUT.
    2. Connect the two RS-232 ports to two PC RS-232 ports.
    3. Running hyper terminal programs on both PCs, send ASCII characters to the TTL-232-5IE converter from one PC port, and check that the characters are received at the 2nd PC port. Repeat the test in the opposite direction. This tests that the transmit and receive functions of both TTL-232-5IE units are working properly.
