DESCRIPTION

The SerialComm USB-4232 is a high quality, high performance industrial-grade bi-directional port powered or external powered 4 port USB to RS232 converter housed in a heavy-duty steel case.  It can convert any standard full duplex USB port to four RS232 ports and is full duplex meaning it will communicate in either direction simultaneously via COM ports on the host computer. The USB to 4 port RS232 converter utilizes the FTDI chipset making it compatible with most computer systems and operating systems.  The unit is powered from the USB port and requires no external power but can also be powered with an external power supply.  It also features data direction auto-turnaround eliminating the need for flow control..  The USB-4232 has a Type A female connector on the USB side and four DB9 male connectors on the RS232 ports.  The software drivers are included with the converter.

The USB-4232 uses the latest FTDI chipset and is fully compatible with Windows 8 32/64, Windows 7 32/64, Vista 32/64, Server 2003, Server 2008, Server 2008 R2, XP 32/64, 2000, 98Se, CE, Mac 8/9/X, Linux

TROUBLESHOOTING INSTRUCTIONS

 

Using one USB-4232 unit:

Perform a loop back test on one unit: Connect the TX to RX on one the four RS-232 ports. Connect the USB connector on the cable to the USB port of the computer Install the USB-4232 FTDI driver on the computer per instructions provided. 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. 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:

Check that all connections comply with the connection diagrams. Perform a loop back test on two units: Connect the two TX to RX and RX and TX on two USB-232-2 RS-232 ports.  Or connect TX to TX and RX to RX with a null modem. Connect the two USB connectors to the USB ports of the computers. Install the USB-4232 FTDI driver on the computer per instructions provided. 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. 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.
