| + | |
| + | There are two types of RS232 serial devices: '''DTE''' and '''DCE'''. DTE typically refers to the serial port on a PC or terminal, while DCE refers to communication devices. Connectors mounted on DTE are likely to be male, and those mounted on DCE are likely to be female. |
| + | |
| + | This device is DCE and has a female connector. |
| + | ---- |
| + | To connect a standard DTE device, use a straight-through Female/Male RS232 cable: |

| + | |
| + | See straight cable pinout below: |

| + | ---- |
| + | |
| + | To connect another DCE device to RUT955, a Null-modem (crossed) Male/Male cable should be used: |

| + | See straight crossed cable pinout below: |

| + | [[File:Straight crossed rs232 cable pinout v2.png|400px]] |
| + | ---- |
| + | |
| + | Maximum cable length is 15 meters or the cable length equal to a capacitance of 2500 pF (for a 19200 baud rate). Using lower capacitance cables can increase the distance. Reducing communication speed can also increase maximum cable length.|}} |
