MC2500 - typical installation

[eboe]

ok, i have a question regarding a diagram i saw in a .pdf file on moto's site. here's a link to the file.

http://www.motorola.com/governmentanden ... csheet.pdf

on page 4 of the .pdf, you'll see a chart with 4 different installation configurations. i'm looking at doing the one on the bottom to control a local CDM1550 to send MDC data (selective inhibit, radio check, etc) with the ability to connect to my MTR2000's in the future by telco for the purpose of in cabinet fall back repeat commands, priority broadcast, radio patch, etc. (hence the remote tone adapter). when i mentioned the part about the punch-block (#DDN6481). he wanted to know what made me think i needed that since the CDM would be co-located with the deskset it wouldn't be necessary. i said that it might not be needed now IF you can just run a line with DB25 to RJ11 between the MC2500 and the CDM1550, but wouldn't it be needed when we incorporate the remote MTR2000's into the system? he seemed to act like i was talking stupid (which may be the case, that's why i'm asking you guys). granted, i have no formal background in system design or engineering, but i thought i understood the basic configuration of the deskset.

maybe he just thought i was going to use the deskset to change channels on the CDM and access the different repeaters via RF. i tried to explain that we're trying to get ready for bigger things and will be going with telco lines in the future, but i think he was already decided that i was an idiot. lol.

he's going to stop by so we can sketch out on paper what i'm trying to do and come up with a list of what's needed to do it. he's a salesman not an engineer so he'll be returning to his tech guys with the sketch for final approval. instead of a blank sheet of paper, i'd like to start out with the page from the .pdf file if it's accurate and i understand it correctly. what do you guys think. did somebody drop a tab of acid in my soda or do i got it right?

thanks

You don't necessarily need the DDN6481 punchblock, but you do need something to parallel other units onto the remote...the punchblock is just what Motorola offers for it. I use a BIX strip with 6 built-in RJ11 connectors to do what you want. Works great, and it looks a hell of a lot better than the ugly punchblock. I even mount them into a hinged ABS plastic box at times, if I don't want people getting at the wires.

ok i understand that. maybe i didn't convey that to the salesman properly though. i was just quoting part numbers that i knew of as examples of what i was looking for. although the 'surge protected' part sounds nice. at least on paper. is it worth it?
