I'm looking to try something that i think is theoretically possible. I would like to find out what it would take to take an IPK system, and possibly make an extension transmit over an LMRS (UHF mobile radio) system. There are more phones in the building than microphone ports for the radio, and this would allow in stant & building wide access to the radio system w/o running to another room to answer local public safety dispatch.
An ideal solution would be a softkey programmed to bring up extension with radio attached, and another softkey right next to it that was "PTT" to key radio (momentary style - nonlatching) System at hand (installed by vendor we no longer utilize)
IPK bearing the following cards; CPUI (200) U10 COIB (4) U30 ESIB (8) U10 VMP (X) U40 (soon to be arriving by fedex) SPE(M) U10 card (which will allow the SAT software i have @ hand to work - correct?)
1) The LMRS radio is cake, i can pretty much program it at will to do whatever i need (radio tech @ heart), but i'm having issues trying to find out what i can do to make the IPK interact. I've explored ideas involving the Door relays and doorphones, but the archaic manual i found online for my system seems to indicate that the relays are adjustably timed from 1-9 seconds based on keypad trigger. This CAN work, but adds a myriad of confusion to the system which needs to be as simple as possible. Can the IPK system trip a nonlatching relay in momentary style without massive hardware hacking?
2) Audio path routing - What are my options to wiring in an audio path to and from the radio? I am going to assume i'm going to need a 1:1 matching transformer in between the two, but what's the safest way to wire in this path? Radio can be tapped for "floating leads", 2 wire or 4 wire output (one path full duplex or 2 half duplex)...but what's the best way to make the IPK interface with it
3) programming - hah, if i can figure out 1 & 2 i'll get to this one next.
4) anyone have an accurate manual for this beast? I have NOTHING.
THanks for all your help!
