Using one USB-4232 unit:

  1. Perform a loop back test on one unit:
    1. Connect the TX to RX on one the four RS-232 ports.
    2. Connect the USB connector on the cable to the USB port of the computer
    3. Install the USB-4232 FTDI driver on the computer per instructions provided.
    4. Running a hyper terminal program on the PC, send ASCII characters to the USB-4232 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 USB-4232 unit is working properly.
    5. When there is constant RX data you should see the associated GREEN light blink. When there is constant TX data you should see the associated RED light blink.

Using two USB-4232 units:

  1. Check that all connections comply with the connection diagrams.
  2. Perform a loop back test on two units:
    1. Connect the two TX to RX and RX and TX on two USB-232-2 RS-232C ports. Or connect TX to TX and RX to RX with a null modem.
    2. Connect the two USB connectors to the USB ports of the computers.
    3. Install the USB-4232 FTDI driver on the computer per instructions provided.
    4. Running hyper terminal programs on both PCs, send ASCII characters to the USB-4232 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 USB-4232 units are working properly.
    5. When there is constant RX data you should see the associated GREEN light blink. When there is constant TX data you should see the associated RED light blink.
