Merry XMAS

gran18

I am sitting here at the office testing a new pcb. It’s soon midnight and I will give up for today in a short while.  We had some snow here today and I really start to get that special xmas feeling.  For me xmas is all about relaxing, reading a good book or two  and look at some movies.  But most of all I enjoy spending time with my family of course as well as eating good food and sip some tasty whiskey. Important stuff in every life.

Through the VSCP project I have the opportunity to get to know a lot of people from all over the world. Many of you have become friends for life. This is really the best part of a project like this.  A lot of you do not celebrate xmas at all, have other festivals, but I sincerely hope the good thoughts of this message reach you anyway just as your good thoughts sent during other festivals reached me during this year. It’s a great honor for me getting  a chance to know you all.

Merry xmas friends!

New product – Vilnius

vilnius_small

The product page is here.

Vilnius A/D module is a CAN4VSCP based module that have four 10-bit A/D channels for  0-5V or 0-10V and also have two 5V I/O channels that can be set as inputs or outputs. General use is to read analog values and as all other VSCP modules you can get the readings reported automatically with a user specified period.

It is also possible to report A/D readings as a VSCP measurement linearized as a floating point value from the formula

measurement = k * A/D-value + m

where k and m are configurable 32-bit floating point constants. You have full control of which event is sent and which unit is used.

This means you can send out any A/D reading as a real unit such as voltage, temperature or in  any other SI specified unit.

You can also assign alarm limits so that alarm events are sent when the level goes above a certain value or below a certain value.

Two I/O channels are available. Both can individually be set as inputs or outputs.  ON/OFF or TurnOn/TurnOff events can be sent out when I/O change state.

The module can be attached to a standard DIN Rail or be mounted directly on a wall. The mounting enclosures are ordered as separate options when the module is ordered.

The module fully adopts to the VSCP CAN4VSCP specification and can be powered directly over  the bus cable with a good 9-28V DC power source. This means there is no need for a separate power cable. VSCP CAN modules are designed to work on a VSCP4CAN bus which use ordinary RJ-45 connectors or use the daisy chain pinhead which can be used to connect modules that are mounted close to each other.  For the bus a CAT5 or better twisted pair cable is used. Bus length can have a total length of 500 meters with drops of maximum 24 meters length (up to a total of 120 meters). As for all VSCP4CAN modules the communication speed is fixed at 125 kbps.

All VSCP modules contains information of there own setup, manual, hardware version, manufacturer etc. When VSCP modules are started up they have a default functionality that often is all  that is needed to get a working setup. If the module have something to report it will send you an event and if it is setup to react on a certain type of event it will do it’s work when you send event(s) to it.  It does not need to be harder than that.
