Troubleshooting guide

Outside data missing
Symptoms: Readings from the outside sensors are missing, but the console display still works in general
and inside readings such as temperature. humidity, pressure, time/date etc are all still present.
On a cabled station, or on a wireless station with just a single wireless transmitter (e.g. just the standard
ISS), all of the outside data is missing. On a wireless station with two or more transmitters then all data
from one transmitter is missing.
However, if only one sensor reading is missing (and with other sensors attached to the same transmitter
reporting normally) then this is of course likely to be a sensor fault rather than a transmitter fault and
troubleshooting should continue with the Sensors topic. (If there is only one sensor attached to a given
transmitter such as a 6372 Temperature Station then it may not be obvious whether this is a sensor or
transmitter fault and both options will need to be investigated.)
This topic is devoted to troubleshooting apparent transmitter faults rather than sensor faults.
Troubleshooting
Wireless station with wireless repeater(s)
If the station has one or more repeaters in use then the first step is to investigate whether a repeater has
stopped retransmitting. See the repeaters topic for further advice. Resume troubleshooting here only if
you’re sure that the repeater(s) are functioning normally.
Cabled stations
It is rare for cabled stations to develop communication problems between SIM board and console, but if a
fault does occur it will usually have one of three causes:
Cable fault: The ISS-to-console cable, especially if it has been extended, can be vulnerable to damage
over time so a through check of cable integrity should be made. Any joints in the cable need inspecting
carefully, as also should the RJ11 plugs at either end of the cable in case one of the four conductors is no
longer tightly crimped into its plug. If there’s any residual doubt about the cable then it’s always worth
testing with a substitute cable, but preferably a genuine Davis extension cable. (The Davis cables are wired
straight-through and while a US-style telephone extension cable may look similar, in practice these are
usually crossed over and will not work with a cabled VP2 station.)
