APPENDIX 2 – DIP SWITCH SETTINGS RF MODEM
1. DIP Switches RF Modem
RS-485 operation (for communication with COMBILOG data loggers using RS-485 interface cable):
(2-Wire half duplex)
RS-232 operation (for communication with PC using RS-232 interface cable):
2. Advanced RF Modem configuration
While XStream-PKG-R RF modems operate out-of-box without configuration, you can use the
supplied Xstream-CTU configuration software to change the parameter settings of the RF modems
(default settings RF modem, see Figure 33) such as:
•
Changing Interface baud rates
•
Advanced addressing capabilities, such as DT and HP (see below)
•
etc
In case two or more
LAS-RET
stations are operational within several kilometres and the user(s)
experience communication problems, the following settings can be modified:
•
Module Address (DT): Used to set the Module Address of the module. Only modules with the
same Module Address can communicate.
•
Network Number (HP): Adjusting the network number allows the module to hop on a different
hopping sequence. This allows independent networks of modules to operate in the same
vicinity.
Important:
Be sure that data loggers that have to communicate with each other have the
same Module Address (DT) and same Network number (HP)!
