Talk:Access Control
Using this as a scratch page. I have decided to completely redesign ThrICE.
MCS
- Arduino shield
- RS485 chip and 8P8C jacks for connections to TCDs and MCS-E
- 4-pin Molex connector for 12v and 5v power (or screw terms)
MCS-TCD Wiring
- 12v
- 12v
- 12v
- Gnd
- Gnd
- Gnd
- RS485-A
- RS485-B
TCD
- 5v power regulator
- 2x relay (RELAY-JZC)
- Header for FTDI
- Header for ICSP
- 8 position dip switch
- Reset button
- 1x 8P8C jack for connection to MCS
- 1x 3-post screw term for power
- 12v
- 5v
- Gnd
- 2x 3-post screw term for relay output
- Normally Closed (NC)
- Normally Open (NO)
- Common (COM) - Will need to be connected to 12v via wire
- 2x 2-post screw terms for RFID readers (opto-isolate?)
- DATA0
- DATA1
- 1x 4-post screw term for sensors (anyway to isolate them?)
