Radio/Serial Telemetry Module User Manual
Page 2©March 2000
Thank you for your selection of the 905 module for your telemetry
needs. We trust it will give you many years of valuable service.
ATTENTION!
Incorrect termination of supply wires may
cause internal damage and will void warranty.
To ensure your 905 enjoys a long life,
double check ALL your connections with
the user’s manual
before turning the power on.

FCC Notice:
This user’s manual is for the ELPRO 905 series radio telemetry module. This device complies with
Part 15.247 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.
This device must be operated as supplied by ELPRO Technologies Pty Ltd. Any changes or
modifications made to the device without the written consent of ELPRO Technologies Pty. Ltd.
May void the user’s authority to operate the device.
End user products that have this device embedded must be supplied with non-standard antenna
connectors, and antennas available from vendors specified by ELPRO Technologies. Please contact
ELPRO Technologies for end user antenna and connector recommendations.
Notices:
Safety:
Exposure to RF energy is an important safety consideration. The FCC has adopted a safety
standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated
equipment as a result of its actions in General Docket 79-144 on March 13, 1996.
CAUTION:
To comply with FCC RF Exposure requirements in section 1.1310 of the FCC Rules, antennas
used with this device must be installed to provide a separation distance of at least 20 cm from all
persons to satisfy RF exposure compliance.
DO NOT:
•operate the transmitter when someone is within 20 cm of the antenna
•operate the transmitter unless all RF connectors are secure and any open connectors are
properly terminated.
•operate the equipment near electical blasting caps or in an explosive atmosphere
All equipment must be properly grounded for safe operations. All equipment should be serviced only
by a qualified technician.

How to Use This Manual
To receive the maximum benefit from your 905 product, please read the Introduction, Installation
and Operationchapters of this manual thoroughly before putting the 905 to work.
Chapter Four Configuration explains how to configure the modules using the Configuration
Software available. For configuration using the on-board switches, refer to the separate 905 Switch
Configuration Manual.
Chapter Five Specifications details the features of the product and lists the standards to which the
product is approved.
Chapter Six Troubleshooting will help if your system has problems and Chapter Seven specifies
the Warranty and Service conditions.
The foldout sheet 905 Installation Guide is an installation drawing appropriate for most
applications.
Warning !
1. For 905U modules, a radio licence is not required in most countries, provided the module is
installed using the aerial and equipment configuration described in the 905 Installation
Guide. Check with your local 905 distributor for further information on regulations.
2. For 905U modules, operation is authorised by the radio frequency regulatory authority in
your country on a non-protection basis. Although all care is taken in the design of these
units, there is no responsibility taken for sources of external interference. The 905 intelligent
communications protocol aims to correct communication errors due to interference and to
retransmit the required output conditions regularly. However some delay in the operation of
outputs may occur during periods of interference. Systems should be designed to be
tolerant of these delays.
3. To avoid the risk of electrocution, the aerial, aerial cable, serial cables and all terminals of
the 905 module should be electrically protected. To provide maximum surge and lightning
protection, the module should be connected to a suitable earth and the aerial, aerial cable,
serial cables and the module should be installed as recommended in the Installation Guide.
4. To avoid accidents during maintenance or adjustment of remotely controlled equipment, all
equipment should be first disconnected from the 905 module during these adjustments.
Equipment should carry clear markings to indicate remote or automatic operation. E.g.
"This equipment is remotely controlled and may start without warning. Isolate at the
switchboard before attempting adjustments."
5. The 905 module is not suitable for use in explosive environments without additional
protection.
