12 Troubleshooting
This section offers possible answers to common installation and/or configuration issues.
Can’t connect to the iRIS via the RS232 port.
Check that the PC application (iLink or terminal program such as HyperTerminal®) is set for the correct comms
port and speed (38400bps). Also check that the iRIS is not in RS232 Only Telemetry mode. This is indicated
by a solid black house icon with an ‘R’ symbol in it being displayed on the LCD. If it is in this telemetry mode,
switch back to normal mode by pressing any key or if currently logged in, then log out by pressing Alt-Enter
from a top level screen. See Section
for details on using RS232 Telemetry mode.
iRIS will not start when the battery is first connected.
Check that the battery voltage is at least 12.2V. The internal battery management hardware is designed to
shut the unit down when the battery becomes discharged to a certain point. It will not restart unless the
battery is deemed to have sufficient capacity for normal operation.
Pulse lost when iRIS connected to other equipment.
In almost all installations where an iRIS is connected in parallel with other equipment to share a common
pulse input (e.g. from a flow meter) there has not been a detrimental effect, as the iRIS presents a relatively
high impedance to the circuit.
However, in the event that connecting an iRIS does cause pulse failure, try removing the debounce selection
link for the appropriate input. This sets the input to electronic switching mode, even if the actual pulse source
is a clean contact (reed switch or similar).
Unable to connect to an IP network.
SIM Card:
Check the SIM card is active and enabled for IP connectivity service.
APN:
The unit must be configured for a valid APN that must also match the SIM account APN.
Signal:
The iRIS will not attempt to connect if the RSSI is 0 or < -113dBm. Use a higher gain antenna
if the signal strength is marginal.
IP Settings:
The iRIS will not attempt to connect unless both the primary and secondary base settings are
defined. (IP addresses and port numbers are non-zero). If the secondary base is not used, set
it to the same values as the primary base.
See Appendix I for a list of the network settings for the HyQuest Solutions APN or HyQuest Solutions Global
Data Network.
iRIS will not respond to SMS requests.
Account:
Check the account is active and the SMS service is enabled.
Power Mode:
If full power save is selected, the wireless modem is shut down.
Connection:
If the iRIS is connected on an IP session, the SMS feature is unavailable. Use a scheduled IP
connection to minimise the time that SMS is unavailable.
Voice Call:
If an iRIS 350FXV is connected on a voice call, the SMS feature is unavailable.
iRIS 350FXV answers a voice call, but no sound is heard.
If the iRIS is currently connected to the wireless network with an IP link the iRIS voice processing function is
disabled. However the internal modem may still answer the incoming call independently but have no audio
available.
