Developer Kit User’s Manual
2.2 I
The development kit serial board is defined as a DCE (Data Communications Equipment). DCE is wired
to interface directly with DTE (Data Terminal Equipment). Typically, DTE is defined as a PC and DCE is
defined as a peripheral. To interface DCE to other DCE, or DTE to other DTE, a null modem is required.
The null modem simply swaps pins to convert a DCE to a DTE and vice-versa. Normally, a null modem
consists of a female and a male DB9 connector. A typical null modem configuration is shown below.
