8.4 Installation guide
8.4.1 How to connect the GPS to UP-2210R
1. Physically install the GPS antenna with a clear view towards the sky.
2. Connect the cable from the GPS antenna to the GPS adapter and connect the adapter
to the Display port on the UP-2210R.
3. After up to 45 seconds the GPS should have started and connected with enough
satellites. The orange LED on the adapter should start blinking once per second. If it
doesn't, check that no object blocks the view from the GPS antenna.
4. Use PQOnline and verify in the UP-2210R configuration that the bps rate on the
computer port is 19200 bps. Also verify that GPS is enabled in the Clock Sync tab.
Finish by sending the configuration to the UP-2210R.
5. Look at the front of the UP-2210R. Every 15 seconds you will see the green LED on
the UP-2210R front go black for a short time. This means a valid time message has
been received from the GPS. If this doesn’t happen, check the port speed settings as
described above.
6. Look on the front of the UP-2210R. After a while the red LED will start blinking
(wait at least 2 minutes). This indicates that the internal clock of the UP-2210R is
synchronised with the GPS. If the red LED stops blinking for several minutes, it is an
indication that the GPS synchronisation doesn't work properly. Start troubleshooting
by checking step 3 above (determine that the GPS is ok), then check step 4 (meter
settings).
7. If more than one UP-2210R should be synchronised by the same GPS, connect
cascade cables beween computer port and display port on the next meter for all meters
in the chain. Repeat step 4 for each meter. The meters' LEDs should then behave
similar according to 5-6.
8.4.2 How to connect the GPS to UP-2210
The procedure is the same as 8.4.1 except that the LED in step 6 on the UP-2210 front will start
blinking with an orange light, rather than red.
8.5 Useful information regarding GPS
When in GPS mode (i.e. the GPS sends valid information to the meter) the meter will not accept time
setting information from either manual operation by PQOnline or automatic setting by PQSchedule.
If the GPS can’t send reliable time information to the meter (it loses contact with satellites, for
instance) the meter will wait for 1 hour before starting to accept time setting from other sources, like
