Notes:
1. The cable distance between the control unit and a MPDM, PT 510D, or 7406D
with data stand cannot be more than 1000 feet.
2. Some host computers act as DCE devices in which case the MPDMs will need to
be replaced with MTDMs or special wiring. If an MTDM can be used, the switch
settings are the same as an MPDM, but you don't need to set auto answer.
3. The cable distance between the MPDM or MTDM and the local host computer cannot
be more than 17 feet.
4. The cable distance between the 7406D and the data terminal cannot be more than
50 feet.
