Productbeschrijving

De 12-90 is een eenvoudig te configureren paging transceiver en repeater met gevoelige ontvanger gecombineerd met een 100mW zender. Het werkt over het frequentiebereik van 446 Mhz. Decodering en codering van 512 of 1200 baud, alfanumerieke of numerieke berichten via deze transceiver.

De 12-90 kan via een seriële interface worden geconfigureerd om numerieke-, alfanumerieke codering te geven. Hiermee kan een gebruiker een pager bellen, een prioriteitsniveau toevoegen (1 van 4) en een numeriek of alfanumeriek bericht toevoegen. Het apparaat ondersteunt meerdere berichten wachtrijen van maximaal 84 karakters, of zo veel kleinere berichten die passen in de geheugenbuffer. Volledige export van seriële wachtrijen en invoer berichten zorgt ervoor dat berichten worden verzonden met minimale overdracht. Pre-gedefinieerde berichten zijn beperkt tot een lengte van 40 tekens en kunnen worden geconfigureerd met behulp van een seriële terminal applicatie.

Twee discrete ingangen worden ondersteund met verschillende voorgeprogrammeerde berichten op hoge en/of lage overgang. De 12-90 is voorzien van de optie om een bericht te verzenden, meer dan één keer en de variabele tijd tussen deze transmissies kan worden ingesteld.

De 12-90 ondersteunt het relais controle protocol om één intern relais te bedienen, plus een aantal "virtuele uitgangen". Virtuele uitgangen kunnen worden gebruikt om periodieke berichten op afstand te kunnen versturen naar pagers / tekstpagers en andere ontvangers. Met behulp van een virtuele uitgang kan het de ontvangen signaalsterkte van het laatst ontvangen bericht doorgegeven worden zodat de positionering van de ontvanger en de systeemstatus kan worden gecontroleerd. Het kan worden geconfigureerd om te reageren met checksum informatie van het laatst ontvangen bericht.

Uitbreiding van de 12-90 is mogelijk met behulp van de 12-34 relaismodule en 12-32 ingangsmodule, zodat elk nummer of uitgangen of ingangen ondersteund kunnen worden.

Een 'channel busy check' wordt gebruikt om bericht duplicatie of fouten te voorkomen, waardoor de noodzaak om berichten opnieuw te verzenden wordt verminderd. Hierdoor is deze repeater geschikt is voor real-time monitoring van alarminstallaties en productielijnen.

The 12-90 Paging Transceiver & Repeater wordt gebruikt voor:

  • Volledig UHF transceiver, voor encodering en decodering van paging berichten.
  • Een stand-alone ontvanger.
  • Een stand-alone transmitter.
  • Page berichten opslag en repeatfunctie welke gedupliceerde berichten voorkomt.
  • Serial RS232 link.
  • Een eenvoudige telemetrische oplossing voor geavanceerde toepassingen.

    So Far, Really Good for Dry and Sensitive Skin
    Size: 8 Ounce, Size: 8 Ounce
    I’ve only been using this moisturizer for about 2 weeks, but so far I really like it. It keeps my skin feeling hydrated throughout the day without feeling greasy or heavy. The texture is smooth, absorbs nicely, and doesn’t irritate my skin at all. I also noticed my skin feels softer and less dry since I started using it. It’s simple, gentle, and works well for everyday use, especially if you have sensitive skin. So far I haven’t experienced any breakouts or strong fragrance issues, which I appreciate. Too early to say long-term results, but my first impression has been very positive and I would buy it again.

    Switched from luxury brands and never looked back!
    Size: 19 Ounce (Pack of 1)
    I used to spend way too much on high end body moisturizers thinking the price meant better results. Tried CeraVe on a whim and realized I was paying for packaging and fragrance this whole time. This does more for my skin than anything I used before. I use it daily all over my body after showering and my skin stays soft the entire day. No irritation ever. The formula is so gentle that I forget I'm even wearing anything. No fragrance, no stinging, no breakouts. Just clean hydration. If you have sensitive skin and you're nervous about trying something new, this is about as safe as it gets. The 19 oz tub lasts a long time even with daily full body use. Ceramides and hyaluronic acid at this price point is honestly ridiculous value. Save your money on the luxury stuff and just get this.

    At this rate, I'm leaving this to my kids in my will
    Size: 19 Ounce (Pack of 1)
    Ten months in and I have barely made a dent in this tub. I am genuinely starting to consider my options — mixing it into smoothies, using it as a cooking fat, applying it to every surface in the house. Something has to be done because at the current rate of consumption this container will outlive me. In all seriousness, the value proposition here is almost absurd. CeraVe Moisturizing Cream is a legitimately great product — dermatologist recommended, ceramides, hyaluronic acid, fragrance free, non-comedogenic, works on face and body, gentle enough for sensitive skin. It does everything a moisturizer should do without irritating your skin or smelling like you bathed in a candle. The 19oz tub is the right call if you actually plan to use moisturizer regularly. A little goes a long way, which is both the best and most frustrating thing about it. Best because you're getting incredible value per ounce. Frustrating because you will be looking at this same tub for the foreseeable future with no end in sight. Great product, generational quantity. Buy it once, pass it down. One star deducted because I now have to figure out what to do with the remaining 18.5 ounces.

    It's not glamorous but it works wonders - even while I am on Accutane!
    Size: 19 Ounce (Pack of 1)
    This is the best, most luxurious lotion I have ever used. And the only lotion that I can even stand to be on my skin. I started Accutane (for acne) last year and was told that my skin would dry out horribly and that I needed to find a good moisturizer to limit the peeling and cracking that I would inevitably experience. Prior to the medicine my skin was oily and very acne prone and every lotion that I had tried either made me feel like I was wearing a latex suit or broke me out horribly. After doing some research I read that this was a great solution and figured I would give it a try. I started it out right away to try to avoid getting dry and was shocked at how well it worked. Even at the beginning when I was still oily this lotion never felt too heavy. Now don't get me wrong-it goes on like frosting and initially feels like a lot-but within minutes it soaks in and leaves your skin feeling like a little kids (not the sticky kind of little kid though-the good clean little kids with undamaged skin). It will last for days too. No need to reapply because it has soaked in to your skin and doesn't just sit on the surface. My skin has never been this soft. And here I am, nearly 9 months in to my Accutane medication regimen and I am not flaking or peeling. In fact, my skin has never looked better or more healthy. My doctors are shocked at how my skin has stayed moisturized because nearly everyone peels. And it doesn't break you out which is obviously something super important. Now, could I be an anomoly? Maybe, but I don't think so. I honestly think this lotion is Just. That. Good! The price isn't bad either!

    Great for dry skin and the whole family
    Size: 19 Ounce (Pack of 1)
    We use this at home for everyone, including the kids, and it works really well. We all have pretty dry skin, and this cream keeps it hydrated for hours. I apply it after showering and it leaves the skin soft without feeling greasy. It has no strong scent, doesn’t irritate, and hasn’t caused any breakouts. I also feel comfortable using it on my kids because it’s gentle and effective. The jar lasts a long time since a little goes a long way. I would definitely buy it again.
