FCC Rules and Compliance
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference that
may cause undesired operation.
Changes or modifications not expressly approved by BENTEK SYSTEMS LTD will void the user's authority to operate the
equipment.
This product is intended for fixed installation applications. In order to comply with FCC/ISC adopted RF exposure
requirements, installation of this transmitter system's antennas must be performed in a manner that will provide at least 6
foot(2m) clearance from the front radiating aperture to any user or member of the public.

Module Address Selection Switch
Each pair of I/O modules, such as the AI4 and the AO4, must share
a unique module address. Once a module address has been
assigned to a pair of I/O modules, that module address may not be
used on any other pair of I/O modules or the same radio pair.
Available addresses are numbers 1 through 8. If module addresses
conflict, or are improperly set within a connected group, an indication
will be given by the STATUS LED (see section below).
The IO900 Transceivers are designed to operate as matched pairs,
and are factory programmed. Manual address configuration is not
required for the transceiver units.
Status LED's
Power LED
Power LED indicates presence of power to the device. It is ON when power is present and OFF when there is no power.
Status LED
When flashing rapidly it indicates an "Internal Error" or a "Module Type Mismatch"
A Module Type Mismatch occurs when the Module Address selection for two different modules (i.e. one (1) discrete module
and one (1) analog module) are set to the same address, or two (2) pairs of modules are sharing the same address.
When Status LED is ON steady, Module Address settings are OK.
RF LED
- Flashes once every two seconds when there is no RF Link
- Flashes rapidly when signal strength is marginal (see RSSI Table)
- ON steady indicates an exceptionally strong RF Link.
- Most systems will flash occasionally indicating the presence of intermittent interference in the area
Discrete
Input / Output
OFF means that the discrete input or output is Open
ON means that the discrete input or output is Closed
RSSI Troubleshooting
RSSI vs DC Voltage
The following RSSI table may be used to test the Receive Signal Strength of
the IO900.
The ideal voltage that should be read from the RSSI test point is 2.5VDC.
This represents a -90dB signal loss and typically indicates that the radio has
20dB fade margin left until loss of link. It is recommended that the radios be
set up with no less than 20dB margin.

+DC Volts
RSSI (Received Signal Strength Indicator) is measured using a DC
Voltmeter between the test point and power supply ground. Test point is
accessed by inserting positive meter probe into the RSSI hole on the face of
the IO900.
