I am trying to identify the manufacturer of an single line LED Display Sign that i recieved, and more importantly the RS232 format to talk to it.
I have very little data on this unit, so google has not provided much success. I am hoping that it may match what others have utilized thier HomeSeer systems.
This is the data that I have.
The unit is a single line indoor display with 15 - 8x8 pixel displays. It looks like it has an IR reciever, and the communications is via an 8 pin (ethernet) jack.
Just after the "Welcome" message on startup, it shows "E1120C", "V4.12", "30 Sep 2004", and "Addr #1". It then cycles thru the capabilities of the sign showing that it also supports colour.
Inside the unit, I have identified that it supports modem, 422 and 232 communications via a 2 row 9 pin header (JP5) used for configuration (3 jumpers per option).
On the board itself there are several identifying marks
"CST-5EN-B" with a date stamp of "2004-04-20". On the one chip there is a sticker with the following 3 lines of info "7120RG", "V4.12", and "2004.11.xx". this is a hand written sticker so could not determine what the xx was in the date.
There is also a CR2032 watch battery and several other 2 pin jumpers. SW1 for termination, SW3 (i think for RS232 comms based on tracing the wiring), SW2 marked Password
I really hope someone can shed some light, as I really want to integrate this sign into my system.
