  • Page 5: Introduction

    The A440 Series 5 Wireless modem will be operated in conjunction with an Adcon A850 Telemetry Gateway. 1.2 Compliance Statement and Warnings The A440 must not be used with any antenna other than the one supplied by Adcon (or an antenna with identical technical specifications).

  • Page 6: Conventions

    Conventions A minimum distance of 18 cm to the antenna is required in order to guarantee compliance with basic safety restrictions. In conformity with the EC Parliament recommendations 1999/519/EG 28V/m is the reference value for the frequency range used. By adhering to any and all recommended reference levels, the compliance to basic restrictions serving the protection of the general public against electromagnetic fields is ensured.

    Gateway is limited, for the complete Base Station. If the A850 is used in combination with one or several Adcon Wireless Modem(s) A440, the Base Station configuration will consist in an indoor unit (the A850) and one (or several) outdoor unit(s), the A440(s).

  • Page 8: Installing The Outdoor Unit

    Note: The cable for the outdoor unit delivered with the system is by default 30 m (about 100 ft) long. If necessary, however, you can increase the distance between your indoor and your outdoor unit up to 75 m by using special cables which can be provided upon request by Adcon.

  • Page 9: Maintaining And Servicing The A440

    WARNING We highly recommend to only use the low attenuation RS-485 cables provided by Adcon with a total length of up to 75 m because attempts to make extensions using other cables could make your Wireless Modem inoperable, due to the voltage loss on the additional cable length.

    Performing Advanced Functions • Command is the command proper, which can be composed of a variable string of characters (for example, ). Each node can implement a set of SLOT commands depending on the functionality of the node itself. However, as a minimum requirement, a node recognizes the CMDS command, which returns a list with the commands recognized by the node.
