I'll "ditto" what Chuck said. LMR-400 should be avoided like the plague in repeater service. If you're not making your cables out of some type of superflex, try RG-214 with proper gender connectors, you can get BNC connectors for this coax. RG-400 is a good choice for interstage wiring, like exciter to PA.
As for the Arcom RC-210's, I feel the same about them as the LMR-400. We had 3 of them at one point, all with v4.74 firmware. One thing I did notice was that on our site with just one repeater and no link radios, it was fairly stable. But, on our other sites (one with a repeater and link radio) and one with two repeaters and IRLP, it was very unstable. After nearly two years of banging my head against the wall, we sought other options. We're now using the SCOM 7330. It has been a VERY reliable performer for us, not one glitch, at all, EVER, since day one. We are doing the same things and more than what we ever did with the Arcom. It was a hard sell to club members because they thought the Arcom was cheaper (they weren't the ones going up there every month to babysit it, either!) But, when you compare the price of an Arcom, pre-built and tested, with cabinet and 3 RAD boards and software cost to an SCOM, which comes standard with the cabinet, 3 audio delay boards, 3 PL Encoders as well, the prices are pretty much the same. If you've ever used hyperterminal, you'll appreciate the ease of programming the SCOM, too, without finicky software to use. I've also had very good success with the CAT line of controllers. They are rock solid, simple controllers, but much less flexible than the new breed of controllers. NHRC also makes good, reliable controllers. I've never used any of the other brands. I know that won't help your "reset" problems, but knowing there are other options out there with the same features. There's so many "fixes" for the random resets hopefully you'll find one that works for you, we never did.
