    IP/UDP frame and sends them to the set IP address and port number of the central system. When encoding messages into IP/UDP frames, the WM868-RFG module uses Softlink’s proprietary ”NEP” encoding system, so the module can only be used for those central applications that use the ”NEP” encoding system. In the opposite direction, the module receives complete radio packets wrapped in IP/UDP datagrams from the superior central system, which are to be sent to the WACO radio network.

  • Page 5: Module Characteristics

    Module characteristics The core of the module is a microcomputer with one Ethernet 10/100 Mb/s communication port, one mini USB configuration port, an integrated 868 MHz radio modem and an integrated GSM/LTE modem. The communication ports serve these purposes: Ethernet 10/100 Mb/s port - the module does not use this port; mini USB 2.0 port - module configuration port;...

    The commands location, contact and name are used to set auxiliary identification data of the module. These data are optional and serve only as its user-editable description. Example: GW33H7-2136#system location Kladno Location : Kladno GW33H7-2136#system contact SOFTLINK Contact : SOFTLINK GW33H7-2136#system name GW868-Kladno Name...
  • Page 14 From the configuration listing, it is clear that the subsystem configuration is saved (Dirty=0), the APN name is set to ”grp.softlink.cz” and PIN checking is disabled. GPS functions and time synchronization are disabled. The ”gsm apn” command can be used for setting the APN (Access Point Name) gateway name between the GSM network and the connecting IP network.
  • Page 15 The ”gsm pin” command can be used for setting the PIN for the SIM card used by the given module for GSM communication. Example of setting the PIN to ”2583”: GW33H7-2136#gsm pin 2583 SIM pin : ’2583’ GW33H7-2136# Using the commands ”gsm useip”, ”gsm gps” and ”gsm synctime” with parameter ”0/1” the individual services of the ”gsm”...

Changing the radio address should only be done in exceptional cases, and always after consultation with the manufacturer! The command ”waco group” is used to set the group address of the module. In the WACO system, group addresses can be used to create an almost unlimited number (65536) of groups (”virtual buses”).
  • Page 17 The ”waco debug” command can be used for setting the desired level of debug outputs that help in diagnosing the module. Example: GW33H7-2136#waco debug 1 Debug GW33H7-2136# The command ”waco test” can be used to set the period of sending a test message. The period is given in ”intervals”, where one interval is 1/20 second (so a value of ”100 intervals”...
  • Page 18 The WM868-RFG module thus supports both ”fast” WACO type communication, suitable especially for imple- menting virtual buses, and ”slow” WACO NB type communication, suitable for collecting data from meters and sensors in larger objects, where the advantage is approximately 2.5 times greater radio range compared to WACO communication.

  • Page 19: Section Of Commands For Checking The Functionality Of Communication Interfaces

    The commands ”rf cw”, ”rf xtal” and ”rf debug can be used only for initial module setup and for diagnostics in the manufacturer’s workshop. The ”cw” command starts generating the carrier frequency when tuning the crystal, the ”xtal” command is used to correct the crystal frequency. The ”debug” command can be used to set the desired level of debug outputs.
