Anyone have much luck doing rs232 to ip with a serial server. I have an old school rs232 comm for two plc controllers I plan to connect to a lan.

The points made are about knowledge no? Being prepared and understanding what it is and how it can react. I am not trying to be arrogant, but I mean if your prepared for the job, and the new...

I will see one with in the year. Looking forward to it. I have heard some horror stories, but I think the stories were dramatized only because it's CO'2. What start up isn't a crazy few weeks. ...

I am excited to having a steady diet of all kinds of ems work again and before too long I will have it in my brain again.

JP, if you recall me telling you, this was the same store where someone...

I was a little too much in a hurry, should have stayed the day I was there and check it all very fine tooth comb but did not.

I did not just walk away, I was poking around at stuff but you know....

I caught that one on this controller. You know as you step up the DB, which btw thanks to you I learned that JP. Any ways, it when you go from whatever to VR2.081, it tells you, that. Tells you to...

For some reason, pulling the old DB, running it through firmware upgrade, then uploading it to the new controller, it swapped 4 esr circuits. No idea why. The old DB same as new, but Markettechs...

That was me. Oh well.

I have a ton to do. It's the database swap over, where you have to suck the old database, and key in by hand over to the new platform, after you do a few, it just gets very old very quick. It...

Oh god. Seen it happen myself. Sparkticians got the job to run and land wire, by whinning about why a reefer guy was originally intended to do it. Big ole mess on that. But they eventually got...

JP, bear in mind buddy, I now again work for an HP Dealer. I am just practicing my lines.

HP is GGGRRRREAT. ;)

Oh God. Thanks for memory lane. And the refresher. I have quite a bit of work ahead of me cutting over these guys. Quite a few.

It's the plugging the existing database to the new I am not...

I had a cpc engineer sales guy tell me one time that you could put any number in the capacity of a compressor in the suction application, as long as the number represented in some fashion the size of...

Jp, I was just asking cause the ones I have been involved with, a total of 3 in my career, not many, 1 in TX, 2 in MI, we did change them.

Its gotta depend on the valve manufacturer. Gotta. I...

JP, so ball valves and what not, your customers are not requiring it?

Like Matt just said Ice. Customer is requiring ball valves and stuff. I did not understand the swelling and just read more about that, your right on.

Its a pretty big job in short time frame...

That's what I have been apart of doing. Oil done ahead of time. And it takes 3 changes to get to 98% I believe they want to see. I might have that % wrong. U have to use a refractometer to check...

I dunno. Thats a pretty optimistic look.

your first sentence is untrue. the second sentence was about pacifying you.

the second statement is accurate. I talk a great game.

what kind of start? CSIR or CSCR? PSC or RSIR? The later two start configs would perhaps be why you would possibly need to look at equalization pressures causing you an issue. You adjusted the...

325 is 123ish Saturated. You got 115ish liquid line temp. So you have subcooling, but flashing through the glass. I would be curious the delta T across the condenser and the TD. I think this...
