5. Installation
IMPORTANT WARNINGS
: precautions in handling the board. Electrical damage
may occur to the electronic components as a result of electrostatic discharges from
the operator. Suitable precautions must be therefore be taken when handling these
components
, specifically:
Before handling any electronic component or board, touch an earthed object
(simply not touching the component is not enough to prevent a spike, as static
electricity can produce a 10000V discharge, which can form an arc of about
1cm).
All materials must be kept inside their original package as long as possible. If
necessary, take the controller from its package and place it into antistatic
packaging, without touching the back of the board;
Absolutely avoid non-antistatic plastic bags, polystyrene or sponges;
Do not pass the electronic components or boards directly to other operators (to
prevent electrostatic induction and discharges).
Connect Lonworks card to the dap4 or Mini-dap4
With reference to Figs. 2- 5 below, insert the board in the dap4 or Mini-dap4 as
follows:
1. Disconnect the power supply to the controller.
2. Using a screwdriver, remove the BMS card cover (
serial card
cover on Mini-
dap4) (see Fig. 2).
3. With cutting nippers, remove the pre-cut plastic part from the cover, thus making
the opening for the 3-pin connector (see Fig. 3).
4. Insert the LonWorks card in the corresponding plug-in connector, initially holding
it diagonally and then making sure it is properly inserted and pushed up against
the two plastic supports on the case of the dap4 (see Fig. 4);
5. Close the cover again, aligning the connector on the card with the hole made in
the cover (see Fig. 5).
6. Reconnect the power supply to the controller; if the BMS 1 communication port
has been set to use the Lon protocol, the red LED on the board will come on for
a few seconds and then will go off immediately, indicating correct operation.
