iRIS 220 / iRIS 320, V1.19 User Guide
8 Troubleshooting
This section offers possible answers to common installation and/or configuration issues.
8.1 IRIS will not start when 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.

8.2 Unable to connect to GPRS network
SIM Card:
Check the SIM card is active and enabled for GPRS 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 less than 6. Use a higher gain antenna if
the signal strength is marginal.
the signal strength is marginal.
Settings:
The iRIS will not attempt to connect unless both Socket A and Socket B settings are defined.
(IP address and port number are non-zero). If Socket A is not used, set it to the same values
as Socket B.
(IP address and port number are non-zero). If Socket A is not used, set it to the same values
as Socket B.
See Appendix F for a list of the network settings for the iQuest APN or iQuest Global Data Network.
8.3 Unable to connect to CDMA network
Account:
Check the account is active and the CDMA data service is enabled.
Signal:
The iRIS will not attempt to connect if the RSSI is less than 6. Use a higher gain antenna if
the signal strength is marginal.

8.4 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:
Connection:
If the iRIS is connected on an IP (GPRS or CDMA-1X) session, the SMS feature is
unavailable. Use a scheduled IP connection to miminise the time that SMS is unavailable.
unavailable. Use a scheduled IP connection to miminise the time that SMS is unavailable.
Voice Call:
If an iRIS 320V is connected on a voice call, the SMS feature is unavailable.
8.5 iRIS will not answer CSD data calls
Power Mode: If full power save is selected, the wireless modem is shut down.

Voice Call:
If an iRIS 320V is connected on a voice call, the CSD feature is unavailable.
8.6 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 320 presents
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). See Section 3.4.5 for details on the digital inputs.
