10.7 iRIS will not answer CSD data calls
Power Mode: If full power save is selected, the wireless modem is shut down.
Connection:
If the iRIS is connected on an IP (GPRS / CDMA-1X / 3G) session, the CSD feature is
unavailable. Use a scheduled IP connection to minimise the time that CSD is unavailable.
Voice Call: If an iRIS 3x0V is connected on a voice call, the CSD feature is unavailable.
10.8 iRIS 3x0V answers a voice call, but no sound is heard
If the iRIS is currently connected to the wireless network with an IP link (GPRS/CDMA-1X or 3G IP), the iRIS
voice processing function is disabled. However the internal modem may answer the incoming call
independently but have no audio available.
Set the IP connectivity using the scheduler so that it has a high availability for voice (short on-line sessions).
10.9 CDMA iRIS 3x0V answers a voice call, but a modem sound is heard
CDMA unit normally has only a single phone number. Determining whether it should answer as a voice or
data call requires the voice capability to be fully enabled.
Enable voice on at least one of the sensors in the Voice menu (option 9 on the Main menu).
10.10 Logged data limits at a value like 32767
The iRIS stores data as a signed 16-bit integer value which has a range from -32768 to +32767. To adjust
the actual measured value for storage, a logging multiplier is applied. If the measured value multiplied by this
factor exceeds 32767, the stored value will limit at that point. Note that the result may be a number like
32.767 after it has been scaling by the unloading application (HydroTel, iLink etc).
See Section 4.4.8 for details on using the logging multiplier.
10.11 Unable to access terminal menu
If the security code has been enabled and this is unknown, then access is not possible. Please contact the
person responsible for setting the code in the first instance. The code is set by an authorised user using
iLink.
However, if the security code is known and yet access is still denied, check the case of the entry is correct.
E.g. Caps Lock key is not on. The code is case-sensitive and must match exactly...
See Section 4.2 for details on the security code.
10.12 Digital output activates when user is logged on
This is normal behaviour. The reason this happens is to enable easy sensor calibration or radio
communication testing when the sensor or radio is controlled by a scheduled digital output. Otherwise the
person on site would have to wait until the next scheduled operation to be able to perform the test.
