2.2 Pin Assignment Supply Power
For definite pin assignment, please see the inside labelling of the mating plugs.
Supply Power 230 VAC
Supply Power 24 VDC (optional)
3 Device Types
This chapter describes configuration and operation of the different interfaces.
Basically, you need the protocols, which are described in chapter “Control Data“.
Depending on the interface, there may be additional bytes. Please see respective
chapter “Operation“ for details.
Power-up: Blinks at a frequency of approx. 2,5 Hz
Normal operation: Blinks at a frequency of approx. 5 Hz
Boot mode: Blinks at a frequency of approx. 0,5 Hz
Software upload: Flickers during the upload
Configuration:
Defective MKS: Blinks with an Error Code: 1x

3.1.3 Operation
Start-Up Procedure:
Segment test
After this, the display waits for valid user data.
If a valid frame is sent during the test routine, the test will complete and after
that, data are displayed.
The controlling of the device happens with the protocols, that are described in
chapter “Control Data“.
3.1.4 Controlling Example
For details see chapter “Control Data”.
The use of the protocol “universal” is required (standard, see chapter “General”).
Demands:
Display with 3 digits and device address 1
Show “1.23”
Data type: unsigned CHAR
Fixed checksum (standard)
Response frame is activated per DIP switch (standard)

Establish a Telnet connection to port 1:
TELNET XXX.XXX.XXX.XXX 1 < CR>
This connection will fail (disconnect within 3 seconds). However, the
IP address is temporarily changed.
Close the Telnet window after acknowledging the error message.
Establish a Telnet connection to port 9999:
TELNET XXX.XXX.XXX.XXX 9999 < CR>
After the connection has been established, immediately press the enter key (within 5 seconds) in order to enter the setup mode.
Enter “0” (Server).
Enter the desired IP address and press the enter key.
Repeatedly press the enter key until
”Netmask: Number of Bits for Host Part (…)“ appears.
Enter here the number of free bits for the IP address,
f.e. “8“ for the netmask 255.255.255.0
(=11111111.11111111.11111111.00000000) or
“11“ for the netmask 255.255.248.0
(=11111111.11111111.11111000.00000000) and press the enter key.
Repeatedly press the enter key until “Your choice?” appears.
Press “9” to save all settings (-> the Telnet connection is interrupted).
Configuration of the Ethernet interface is now complete.
Now, the control frame can be transmitted to the display via the selected
IP address (TCP/IP connection via port 10001).

3.2.2 Operation
After start-up, a segment test is performed.
Subsequently, after establishing a TCP/IP connection with adjusted IP address
and port 10001, the device waits for valid user data.
The controlling of the device happens with the protocols, which are described in
chapter “Control Data“.
