INSTALLING THE WI-FI BRIDGE ON A DKN-XXX OVEN
1.
VS-4 Wi-Fi Bridge modules:
The Wi-Fi Bridge is implemented as two interconnected modules: One module is installed inside the oven, next
to the Planar board, and another module is installed outside the oven, next to the Option Terminal Block
located on the right side of the oven. To install the module inside the oven, first make sure AC power cable is
disconnected from main Power and Main circuit breaker is set to Off.
2.1.1
Power Supply and RS485 to TTL converter module installation
The Power supply/RS485 module has two harnesses and one USB type A female connector: The AC power
harness is terminated two female receptacles (blue or Pink color). Those receptacle should be inserted on
vacant positions of Terminal Blocks TM1, labeled
“1” and “2”,
The two wire communication harness should be
connected to VS-4 CN3, pins 3 and 4. If you received a unit with a shielded cable on a 4 pin header block, plug
this connector on VS4 connector CN3 so that the coaxial cable “sits” above CN
-3 pins 3 and 4, not pins 1 and 2.
If your device has a two wire connector, the Black wire should be aligned to pin 4 of CN3, while the lighter color
wire (white or yellow) should be on pin 3.
The supplied USB “A” to Micro USB
6’ cable should be connected to
the power Supply module on the “A” side. T
he Micro USB end of the cable should be routed to the outside of
the oven enclosure and connected to the Control and RF module. Remove the extra metal cover plate located
next to the Option Terminal block and use that opening to string the cable out. See figure 1.
