Maximum cable length is 15 meters or the cable length equal to a capacitance of 2500 pF (for a 19200 baud rate). To connect another DCE device to RUT955, a Null-modem (crossed) Male/Male cable should be used: To connect a standard DTE device, use a straight-through Female/Male RS232 cable: This device is DCE and has a female connector. Connectors mounted on DTE are likely to be male, and those mounted on DCE are likely to be female. DTE typically refers to the serial port on a PC or terminal, while DCE refers to communication devices. There are two types of RS232 serial devices: DTE and DCE. Output (connected to +3.8V permanently via a 4.7k resistor) DCE stands for Data Communication Equipment. The RS232 connector type on this device is a DCE female. General information RS232 connector pinout This manual page provides an overview of the RS232 page in TRB142 devices. The RS232 page is used to configure the operating parameter of RS232 serial connector.
