sensor (for pinouts, see Table 16 on page 39). Configuration 6 is similar,
except that the GPS sensor takes the SC-104 corrections from port 2,
either RS-232 or RS-422 (for pinouts, see Table 17 on page 40).
You can easily switch between internal BDM and
external SC-104 operation simply by opening or
grounding pin 23 on the connector.
Configuration 5 (for pinouts, see Table 15 on page 38) is used with the
Northstar 8800, which only contains a BDM. Inputs and outputs from
both BDM ports are available in RS-232 and RS-422 signal levels.
