I´m a complete noob to arduino, electronics, etc, but not to programming.
I decide to buy an arduino board to try just for fun.
However I noticed that it have many applications.
I don´t understand much of electronics, but I want to use arduino to send events to a gps positioning equipment.
The gps accepts 5 v TTL > 1 msec with at least 7 ma.
I would like to know if I can connect directly the cables from the output pins (to a DB9 male plug, since the gps input port it´s DB9 female) without having to make a circuit with other components.
I have the following desription in the gps manual:
** Event 1 In and Event 2 In are optically isolated digital inputs.
** Inputs (and their return lines) are not referenced and are independent of
internal mPOS power supplies and GND.
** Inputs can be controlled from an external 5V TTL-level source capable of
supplying a minimum of 7 mA of sourcing or sinking current.
** Examples of possible configurations of Event 1 and Event 2 inputs are
The images of the examples are in the reply:
Tks to everyone
