    2 SYSTEM COMPONENTS The system consists of the following components: • HD35AP… base unit • HD35RE repeater • HD35ED… series of data loggers • HD35ED-ALM remote alarm device HD35AP… B This device acts as an interface between the network data loggers that are positioned in the measurement sites, and the PC.

  • Page 6: Installing The System

    3 INSTALLING THE SYSTEM Before placing the devices in the final working environment, it is recommended to perform the system function test on the bench. The bench test allows also the wireless network to be con- figured more easily, in case the supplied system is not factory-configured. To check and make the system operational, proceed as follows: 1.
  • Page 7 1. I HD35AP-S NSTALLING SOFTWARE The base unit is supplied with a CD-ROM containing the HD35AP-S software and MySQL Data Base Management System. Install both HD35AP-S and MySQL in your PC. Concerning the in- stallation of MySQL, thoroughly follow the installation guide contained in the CD-ROM. 2.
  • Page 8 Note: even the base unit HD35APW, with Wi-Fi and Ethernet interface, must first be connected to the PC via USB through the CP23 cable for setting the parameters of the local network (e.g., for setting the IP address, for choosing the Wi-Fi or Ethernet mode, etc.). 4.

A DDING REPEATERS TO THE NETWORK If a device is not reachable after installation (it fails communication with the base unit), it could be necessary to install one or more repeaters in intermediate points between the device and the base unit. To add a repeater to the network, connect the internal battery to the repeater and repeat the installation procedure from step only for the repeater.

    5 INSTALLING THE HOUSING FOR INDOOR USE The installation of models in indoor-use housing can be fixed, by means of anodized-aluminum flanges to be attached to the back of the housing, or removable, by means of a practical plas- tic support to be fixed to the wall. The use of flanges allows preventing the instrument to be taken away, thanks to the possibility of applying a padlock, inserted in a fastening pin to be fixed to the wall.
