PELCO D commands















RJ45 - Reverse Polarity 


1. Connect LAN board to any PC or Laptop and using this procedure enable DHCP:




2. Connect board to FRITZ!Box and check IP board (in this example





3. Click on IP address and open Relay board WEb Server




--- Tested with FRITZ!Box 7390 ---











KEEProg EEPROM programmer




Download Software and Drivers from:







UnZip in separate folder ( in example D:\KEEProg )



Open Device Manager


Connect programmer to PC



Click on KEEProg EEPROM PROGRAMMER and next Update Driver...



Click on Browse my computer ...



Locate driver’s holder and click Next


Wait until Windows install driver




Windows will show confirmation message that drivers are installed




Close and open again Device Manager to check that KEEProg programmer is now installed

KMtronic Modbus LAN TCP/IP to Modbus RTU RS485 Serial Communication Module Converter












... On the configuration program just go to Periphery - Devices - RS485 Extension and

just use the following communication parameters: 8 Data, 1 Stop, No Parity, Baud rate : 9600.

Now add a RS485 actuator. Click use as digital output,

write \xFF\x01\x01 on "Command for on" and \xFF\x01\x00 on "Command for off"

and you can control the first relay channel.

Repeat the above for the other relays (\xFF\x02\x01 and \xFF\x02\x00 for the second, so on)....



Thank you Vampiris!
