Table 13 below contains the hardware port numbers and signal levels
available on all the sensor's connector pins. Specific signal assignments
for standard 8700, 8800, and 8900 configurations are found in Section 9,
"Connector Pinouts."

Table 13: Hardware pin numbers/signal levels

Pin # Signal level
1 RS-422 input 2A
2 Ground
3 RS-422 input 1B
4 RS-422 output 2B
5 RS-422 output 1A
6 RS-232 output 1
7 RS-232 input 1
8 Ground
9 RS-232 output 3
10 RS-232 input 3
11 Configuration pin B
12 Remote ON
13 (–) DC power input (Ground)
The SC-104 port supplies differential corrections. The port characteristics
are listed below.
Signal type: RS-232 or RS-422
•
Data format: RTCM SC-104
•
Baud rate: 4800 or default of 9600 (8 bits, no parity, 1 stop bit)
•
Jumper-selectable.
•
There is some lack of industry-standard labeling of
RS-422 pin pairs listed as A and B or as + and –. If the
interface doesn't work, try swapping the polarity of
the pairs.
