ELAN AUDIO - SENTINEL / RCU-01 RCU01R02 PAGE 3/49
The 12V 7AH Gel Cell is a common Re-chargeable battery, and available off the shelf from most electronics
component suppliers. ELAN Audio is unable to supply and ship these batteries by air with the RCU-01, as they
are prohibited as general Air Cargo.
ELAN Audio recommends and supplies the Maestro "Woomera" Modem. The Maestro "Woomera" is an
Industrial Modem having a number of special features, including the ability to operate from 9V DC supplied from
the RCU-01, which is essential to maintain communication with a remote site during mains power failures.
Further development is planned for the SENTINEL system where external 'Intelligent' units will plug into the RS-
485 Serial Port and expand the Input and Output numbers, and also manage 'Pairs of Transmitters' making the
SENTINEL system suitable and economical for use on shared Transmitting sites.
Control Site
Minimum Hardware Requirements
• PC running WIN95C / 98 or NT4
• Pentium 100 or better processor
• 32M of RAM
• CD-ROM
• 5M of free hard drive space
• VGA screen
• One spare serial port.

The Control site runs the SENTINEL Software which allows control of up to 100 'Remote Sites'.
The SENTINEL software features a 'Dial Out' routine which can automatically dial two designated SMS Digital
Mobile Telephones and deliver a text message to them. Each site can page to different mobiles.
Other features possible on the 'Control Site' PC is second Modem, a Relay Output Board for Alarms off the
parallel port, and a Multi Port RS-232 Board if required.
Some of these features will require Software Customisation. Please consult ELAN Audio.
Standard Program
As supplied, the SENTINEL system is programmed with a simple 'Default Program' which is suitable for
demonstration and tests of the system only.
This 'Default Program' is internally held in EEPROM in the RCU-01 as the Operating Program, and may be
altered by the customer to become a working program.
This can be done from a PC at the 'Remote Site' by temporarily connecting directly into the RS-232
Communications Port, or remotely from the 'Control Site' via the 'Modem' and Communications Link using the
SENTINEL Program.
Site related parameters, such as Site Identity and Dial Out number is normally programmed into the 'Remote Site'
unit from the 'Control Site'.
