=WORK IN PROGRESS=
PoE node voor the [[Ceramic Oven / Keramiek Oven| Ceramic Oven]] based on a [[PowerNode White]]. The QR code points to [[https://wiki.makerspaceleiden.nl/mediawiki/index.php/QR_ceramics this]] page.

==Use==
...
==Trouble shooting==
See [[PowerNode White]] for details; or use the MENU button to see a QR code with logging.

 "mac": "34:98:7A:70:B0:E4",

The log file is available on http://192.168.6.91/. 

One can also telnet to this address. Logs are also sent to MQTT and to Syslog at the firewall. Or connect a USB cable; the use [[Galvanic USB isolator]] is wise; but not strictly needed (as it is AC/mains powered).

==Configuration==
See [[VK2000-build]] voor a lot of details.

==Board jumpers and settings==
Board:

# Rework 1 - half of OPTO resistors replaced by jumpers; 2x68k left in place
# Current coil - 6k8 burden
# Relay 1: Normal 5v Songle relay
# Relay 2: Normal 5v Songle relay
# AC/DC unit soldered in
# Fuse soldered in (100 mAmp, slow)

Jumpers:

# VPOE and VPOE5 both explicit on 'off'
# 5V power via VINT
# Vpower via VINT
# N-jumpers for the Optocouples to get the N from the inputs.

==Green Connector==

The heating current goes directly through the coil; we're not making use of the connector. Reason for this is that we're not quite sure of the (starting) currents.
