Input signals may be connected to any appropriately labeled input pin,
and output signals may be taken from any appropriately labeled output
pin. Choose either RS-422 or RS-232 pins as required by the host device.
Both RS-422 and RS-232 outputs may be used simultaneously; however,
only one receiver input for a particular port should be connected. You
may use other pins if complex installations require additional inputs or
outputs.
BDM RTCM SC-104 output: The primary output pins supplying dif-
•
ferential corrections.
BDM monitor output: ASCII status messages from the BDM.
•
BDM control input: NMEA or binary commands to the BDM.
•
BDM monitor input: NMEA or binary commands to the BDM.
•
Echo port: An exact copy of the noted inputs.

The 8900's configuration pins should be wired as shown in Table 16, with
connector pins 11, 23, and 24 left open. With this configuration, SC-104
signals pass directly from the BDM receiver to the GPS receiver. In this
configuration, signals appear on the connector pins as described below in
Table 16 (functions highlighted in bold indicate the suggested pins for a
normal installation, and are the minimum connections required for oper-
ation of the 8900):
