You can use one of the following diagrams to build an RS232 cable: Any other cable you have will work if you can verify that pins 2, 3, and 5 on the RMC-end of the cable are connected as shown in the above diagram. An Ohmmeter or continuity checker will work for verifying the cab...
If the RS232 equipment being connected is a D ommunication Equipment (DCE) device, it’s typical that a straight- through cable can be used. DTE Pin Number Signal Name DCE Pin Number 1 DCD = D arrier Detect 1 2 RXD = Receive Data 2 3 TXD = Transmit Data 3 4 DTR = Data ...
The Digilent PmodRS232converts between digital logic voltage levels to RS232 voltage levels. The RS232 module is configured as a data communications equipment (DCE) device. It connects to data terminal equipment (DTE) devices, such as the serial port on a PC, using a straight-through cable....
