The Trident Raider/Marauder controllers used a simple Null modem cable for a direct connection to a computer running Hyperterminal or their own Trident "T-comm" version.
From what I recall - all the units shipped with a default password of "Master", and you could re-set the panels to a default condition if you needed to. The tables to set up a "conventional" Tone PL or DPL were a little quirky, but easy enough to deal with once you got the hang of it.
What I liked was their ability to set up CWID on a per-user basis, along with the ability to enable certain features (or not) on a per user basis. You could also put the CWID down in the weeds with some lower deviation, and adjust the WPM settings. They had plenty of adjustability, and did do a fine job of decoding and encoding. Not too many problems with falsing.
I always considered them to be "plug and play" units that didn't require tons of setup (unless you wanted to complicate things) and they were rock solid. Never had a problem with them that I didn't cause - all by myself. The Marauder panels even had a type of "dial up networking" that would allow you to link distant sites by phone lines on an as-needed basis. I never had a need for that, but thought it was a neat feature.
I believe Motorola bought out Trident Microsystems around the time they started to offer Passport LTR in the CDM/Pro Series/Waris line up. They fizzled soon afterwards. I've still got some LTR panels in operation - 20+ years now, so I still carry some spares, but I bet I haven't hooked up to a panel in 5+ years.
