So we have an Inner Range alarm system at my work.. It’s a great system, but like most alarm vendors, the manufacturer thinks tight lips is a good policy.
Yeah, no.
$99 for a ‘port 0’ cable to program the alarm boards is a huge rip-off, so I sat down before work this morning and figured out how to talk to them. It’s just TTL RS232.
On the CLOE devices, there’s a 5-pin header. Pinout is as follows:
1 GND
2 UNKNOWN
3 RXD
4 TXD
5 UNKNOWN
Honestly, I don’t care what the unknowns are, probably flow control? however wiring GND, RXD and TXD to a USB->TTL RS232 adapter (With the appropriate swapping of RXD/TXD betwee ends), I’m happily talking to this device at 115,200, so I’m happy and can now program it without finding the $90 cable that’s gone missing :-p
Thanks bud … yes I agree
I don’t understand the thought process behind this kind of gatekeeping. Great work on figuring it out and publishing the info. It will help others.
