This document describes how to configure your unit using the default factory configuration that
lets you easily setup your network as a simple send/receive network using a dedicated pair of
transmitter and receiver units.
The basic steps for using your unit are:
1. Connect the antenna, power supply and transducer signals using the instructions in
this document. Power supply and transducer connection is described in the section
Unit components and connections. Antenna connection is described in the section
Antenna installation. For more information, see the WI-I/O 9-L-x Install Manual.
2. Reset the transmitter and receiver units to the factory default configurations.
3. Link the transmitter and receiver units to work as a dedicated pair.
4. Bench test your configuration before deploying.
NOTE: You can also configure your network using a user-defined customised configuration that
lets you set specific information about your network. For more information on setting a user-
defined customised configuration, see the WI-I/O 9-L-x User Manual on the enclosed CD.

The front panel contains the following components:
The triangle on the rotary switch indicates the current position, for example:
NOTE: To avoid damaging the rotary switch, use a screwdriver to change the position.
The rotary switch uses the following setpoint levels:
Position Lower level (mA) Upper level (mA)
1 4.8 6.4
2 6.4 8.0
3 8.0 9.6

The LEDs on the front panel indicate the unit status:
LED Status Indicates
None No power supply.
OK LED Green Current status of the unit OK.
OK LED Red Fault condition detected in unit.
TX Led Flashes Transmitting Message.
PG LED on Configuration Cable Connected.
Input LED ON Input LEDS (i.e. D1,D2, SP, AZ.) light when the corresponding input is active.
D1 Digital Input 1 is active (Low).
D2 Digital Input 2 is active.
SP Analog Setpoint is active.
AZ Analog Input is zero mA
All LEDs medium flash Medium speed flash (1.6HZ) indicates the module is half-way through the
configuration process. Medium flash also happens when you set the rotary switch
to position 0 when powering on the unit.

To reset the default factory configuration:
1. Set the RSSI rotary switch to position 0 using a screwdriver.
2. Power on the WI-I/O 9-L-T transmitter.
3. The WI-I/O 9-L-T transmitter flashes all LEDs at medium flash (i.e. 1.6 Hz).
NOTE: If the LEDs do not flash, you must repeat steps 1 and 2 until the LEDs flash before
continuing.
4. Set the RSSI rotary switch to another position (i.e. position 1) within 5 seconds.
5. Set the RSSI rotary switch to position 0 within another 5 seconds.
6. The WI-I/O 9-L transmitter lights all LEDs for 2 seconds before returning to normal
operation.
NOTE: If the LEDs do not light for 2 seconds, you must repeat the process from step 1
until the LEDs light before continuing.
7. You can now link the transmitter and receiver units.

You must reset the transmitter unit to factory defaults (to disable encryption) before linking the
transmitter and receiver units. For more information, see the previous section.
NOTE: You must complete the linking process in 60 seconds.
To link the transmitter and receiver units:
1. Press and hold down the RSSI Pushbutton on the receiver.
2. Power on the receiver while holding down the RSSI Pushbutton
3. Release the RSSI Pushbutton as soon as the Receiver LEDS flash (within 5 seconds
of powering the receiver).
4. The receiver will flash all LEDs for a maximum 60 seconds while it tries to link to the
transmitter.
5. Power on the transmitter. The transmitter sends a special “Link” message to allow the
receiver to recognise the transmitter.
6. When the units link, the receiver lights all LEDs for 2 seconds before returning to
normal operation.
NOTE: If the receiver LEDs continue flashing within the 60 seconds, the units are not
linked and you should retry the linking process by powering the transmitter off and on
again. If you exceed the 60 seconds, you must restart the linking process from step 1.
7. You can now bench test your configuration before deploying.
