Appendix B RS-232 Pin Specification
The RS-232 serial port of the TE100-S55 uses a 9-pin female
connector. The port can be connected to a PC emulating a VT100
terminal or an actual VT100 terminal.
For a local connection, the table below shows the pin layout of a
9 to 9-pin or a 9 to 25-pin cable connection between the
TE100-S55 and the management terminal.
