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.<\/p>\n
Yeah, no.<\/p>\n
$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. \u00a0It’s just TTL RS232.<\/p>\n
On the CLOE devices, there’s a 5-pin header. \u00a0Pinout is as follows:<\/p>\n
1 \u00a0GND
\n2 UNKNOWN
\n3 RXD
\n4 TXD
\n5 UNKNOWN<\/p>\n
Honestly, I don’t care what the unknowns are, probably flow control? \u00a0however 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<\/p>\n
