Option 0
Select this option to return to the Output Selection menu.
Option 1
When this option is selected you will be prompted to enable/disable the output.
> Enable (0:No 1:Yes)=
Enter a value of 0 if you want to disable the output. Enter a value of 1 if you want to enable it.
Option 2
When this option is selected you will be prompted to select the switching polarity of the output. This relates to
the output’s electrical state with respect to its logical on/off state.
If the polarity setting is 0 (normal), the output will be electrically on when the output logical state is on and be
high impedance (open-circuit) when the output is logically off.
If the polarity setting is 1 (inverted), the output will be high impedance (open-circuit) when the output logical
state is on and be electrically on when the output is logically off.
> Polarity (0:Normal 1:Inverted)=
Option 3
When this option is selected you will be prompted to enter a number representing the operating mode of the
output.
> Mode (0..6)=
Valid modes are:
Source
Description
0
Follow wireless link state. I.e. Output is on if communication link is on-line.
1
Follow Schedule as defined by the settings in Options 3-6 described below.
2
Remote Control from Base. DO1 is controlled by bit 0 of d1000, DO2 by bit 1 of d1000.
3
Low Trigger. Activate when Sensor 1 last logged value <= trigger setpoint and trigger enabled.
4
High Trigger. Activate when Sensor 1 last logged value >= trigger setpoint and trigger enabled.
5
Force output permanently on. Required for DO2 output if Unidata high-speed encoder used.
6
The output is on if any sensor alarm is active. Turns off when all alarms are inactive.
If DO1 is set to Mode 1 (Schedule) AND the Power Save mode is set to 3 (RS232 Only), DO1
will be forced on when an alarm requiring transmission to a base station is pending. This is
to enable an external radio to be powered up in order to transmit the alarm call-in. After
successful acknowledgement, the output will then remain on for the Duration configured in
Option 4 below.
If DO2 is set to Mode 1 (Schedule) it will be forced on while a user is logged on via the
LCD/keypad interface. This is to power up controlled sensors for calibration purposes.
Option 4
When this option is selected you will be prompted to enter the length of time in seconds that you want the
iRIS to keep the output energised for if the mode is set to 1 (Schedule).
