WRM-TS starts work immediately after power-up. All leds are lit for 0.5 seconds during initial startup, then device
enters normal mode of operation. This means that it is expecting commands on its serial and m-bus ports, while listening for
incoming wireless messages from remote meters.
WRM-TS are set only through serial interface commands.
Serial interface can be set to different speeds to match external reading device.
For wireless device data to become available particular device must be ACTIVATED in WRM-TS memory.
Once activated it is regularly read and updated. WRM-TS itself keeps track of time and saves timestamp with each record.
There are no historical values. Read period can be set in minutes or hours, with maximum value of 240 hours
and minimum value of 5 minutes.
Normally three scenarios can occur:
- Connect WRM-TS to master m-bus converter/display,
like MBM-64/250 – then data will be visualized on display or read through
wired m-bus interface
- Connect WRM-TS to communication device like Ethernet/GPRS/phone modem –
then data can be read from remote location
- Connect portable computer to RS-232 port and read information manually
To start reading particular device there are two main steps that must be done:
- set WRM-TS in desired wireless m-bus mode
- activate a device in memory
- *set desired interval for memorizing
*by default this value is on every 6 hours
Normally device is “listening” the air for incoming transmissions. It can be set in two modes:
- work with filtering – “Normal mode”, which means that all transmissions that do not
have proper headers, are rejected
- work in “Accept all” mode, which means that every message in the air is processed
If one is not sure in which mode should work – we recommend using “Accept all” mode
(which is default by the way). There is only one scenario in which filtering must be used
– if wireless data is AES-128 encrypted.
Most of WRM-TS commands are ASCII-based, so setting can be done with simple terminal for RS-232. Anyway,
there is special Gineers software for quick and easy setting of this device, including searching for
wireless meters in range and activating them in WRM-TS memory.
All commands are detail described in WRM Command reference, which can be freely downloaded.
