Node Tussendeur

Logging	[telnet], serial 8N1, 115200, [http], mqtt:///#ac/log/tussendeur mqtt and syslog to the space local server.

You need to be on the local LAN/Wifi of the space to be able to use the above telnet and http links.

Normal operation

Swipe your card - node should beeb for 4 seconds; or give a short intermittent deny signal.

Bypassing the node

Bypass dip switch

With the explicit permission from a trustee - a node can be bypassed. For example when it is broken. There is a red dip switch on the back of the board; near the AC/DC transformer and the fuse.

Placing it in the 'on' position will bypass the node (i.e. to the left in the picture); and provided power to the solenoid.

Obviously - doing so without the express permission is a sure way to loose your membership.

Trouble Shooting

Check what is on the display. The first QR code will bring you to this page. The second QR code will show you the logs in a browser. You can also telnet to the IP address shown in the 'MORE' display to see the log in real time.

See this page for more details.

Swipe ok - but does not want to open door

1. Do you see waiting for card on the display ? If so - it has not read your card (yet).
2. Did you hear one or more beebs when you swiped ? If so - your card is picked up ok ?

If you hear beebs:

1. Did you hear 3 or more beeps when you swiped ? If so - your card is not getting permission from the system.
   1. Does your personal page in mijn.makerspaceleiden.nl show that you have permission ?
2. Did you get your permissions quite recently ?
   1. Is the internet in the space up and running (as it only periodically updates its database).

The Machine does not want to accept my badge

1. Do you hear a beeb when swiping ? If so - it has read your card -- and see above issues.

If it did not beeb:

1. Did it work on the door ?
2. Does it work on any other machine ?

If so - your badge is fine - but we may have a broken ACNode or a broken reader. Report this to the mailing list - or if you know a little of IT and electronics - go to the troubleshooting section and connect to the log via your webbrowser or via telnet. Then swipe again and see what really happens.

Note that we are, at this time, not sure if these nodes will survive the welding area.

Resetting the Node

Unplug the ethernet cable in the main patch cabinet. See this page for details.

Wait at least 60 seconds until you try again (the ESP32 is quite slow & it needs to create some cryptographic date before it can start communicating over https/SSL).

Electronics

De node is PoE powered; set to 12 Volt.

rfid scanner

The middle section is broken out and, with an 6 wire, RJ12 socketed (ISDN) wire, interconnected.

So the main PCB is inside; the RDID bit is outside. The wire carries i2c, 3v3 power and the 2 reset/IRQ signals.

The wiring is straight; RJ12 wiring:

Board jumpers and settings

Note diode and red/black wire to bring 12v to the solenoid, blusdiode over solenoid

Board - Serial #5

1. Rework 1 - verwijderen ESD diodes antenne
2. Rework 2 - omdraaien transistors programmering
3. 0-ohm (jumpering) R109 removed; 5V of USB not connected to 5V rail.
4. Fixed 5v resistor replaced by potentionmeter; and set to 7 (was12) Volt

Jumpers:

1. Vpoe - set to 'Slow Start'
2. Vpoe5 - set 'Slow Start'
3. Vpwr - set to 'Vpoe' as source.
4. 5V- set to 'Vpoe5' as source.
5. Out2 - via the two AC jumpers

Special Wiring

The 12 volt DC of VPoe is wired to L/N of the normal 220V AC input. So that the C/NO of relay 2 is a simple 12 volt on/off.

There is an extra diode wired across the coil-wires.

Connectors

Green Connector

Node tussendeur, connector for solenoid at the bottom; note large capacitor

Only the bottom 2 sockets are needed/switched - and can be wired 1:1 to the solenoid.

current and solenoid

Somehow the solenoids current increases at 12Volt to a point where it needs well over 30 watt. At which point the PoE switch current protection trips.

Solved for now by reducing the voltage to about 7 volt. No trips observed since.

Gele draad RJ12/6 aderige kabel naar de buiten RFID scanner. Witte kabel met RJ45 stekker - ethernet; Grijze kabel met groene stekkertje - naar Solenoid.

Zaak hangt nu in het kastje.
