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.
