3 Set Up Your System
Connect multiple receivers
When you configure multiple receivers, only one receiver (the
master receiver) is physically connected to the computer and is
able to supply input from the GPS. You attach an external GPS
system (unless it has internal GPS) to the master receiver only.
The other receiver(s) receive their GPS signal from the master
receiver. If other receivers contain internal GPS systems, their
GPS is ignored.
To connect multiple receivers:
1 Attach one end of a short cable to the RX LOOP IN connector
on the master receiver. Attach the other end of the short
cable to the RX LOOP OUT of the second receiver.
2 Continue to attach receivers (up to a total of four receivers)
as in step 1.
3 When all receivers are connected with short cables, connect
one end of a long cable to the RX LOOP OUT connector on the
master receiver to the RX LOOP IN on the last receiver in the
series.
4 Connect the serial port of your laptop to the RS-232 port of
the master receiver with an RS-232 cable.
5 Connect the RF antenna to the RF input of each of the
receivers.
