This is required because the front port on Orion is fixed at 19.2kB and WinECP cannot support a baud rate that high. Note: Accessing Orion via dial-up or Ethernet is also possible. This note details only direct physical connection via RS232. Set the comm parameters of the MMI Interface port to the same parameters as the comm port on the PC.

Some versions of NCD refer to “Passthru Interface” as “Direct Interface Client”.
