Notes: Figure 13, Figure 18, and Figure 19 are special cases requiring custom cables.
The NCM, Companion, and DX9100 RS232 ports have identical pinouts.
Standard null modem cables do not normally have a jumper from DCD to DSR. At Metasys Release 8.0 and
later, this jumper is required for proper operation.
