GINEERS WM-BUS Series Instruction Manual

3. Electrical connections

All connectors of WRM-TS are shown on the figure on the right:
1 – Power inlet: adapter 6-9 Vac/200 mA
or 5-12 Vdc/200 mA (polarity does not
matter)
2 – SMA antenna connector
3 – Wire m-bus slave interface, 2-pin
terminal block
4 – RJ45 connector (RS-232 interface) -
for connection to PC, external
controller/converter or m-bus converter
(MBRS-xx)
The cable for connecting WRM-TS to external device (PC, controller, etc.) is RS-232
<-> RJ45 and is part of the package. Same cable is used on MBRS-xx type converters.
Software for setting WRM-TS can be freely downloaded from Gineers website or contact us.

4. Warranty

The warranty of the device is limited to 2 years from the date of sale. If the device
shows any defect or malfunctions during that period, the manufacturer is obligated to repair

Wireless m-bus receiver WRM-TS
Instruction manual
WRM-TS is a wireless m-bus receiver, intended to collect data from various devices,
working in modes T or S according to wireless m-bus standard (EN13757-4). WRM-TS have
the following main features and characteristics:
Serial RS-232C interface for communicating with external device (computer,
communication device/controller, etc.)
wired m-bus interface, slave device in a m-bus network
memory for saving data for up to 450 devices
real time clock
several LEDs for work state information
external power supply (adapter 12V@0.5A), included

2. WRM-TS operation

WRM-TS is powered by external adapter 5-12 Vdc/200mA. The central pin of the power
connector is 2mm thick. We recommend adapter with power rating 6-12 Vdc/5W. Power
supply voltage should not exceed 20 Vdc/ 15 Vac.
WRM-TS begin operation immediately after power-up. After initialization (about 1s),
WRM-TS enters in normal work mode.
This device has simple function – collect data from every wireless meter which is told to,
and convert this data to normal m-bus telegram. This telegram can be read both through PC
interface and/or m-bus interface by external controller. It is ideal for mixed type networks
(wire and wireless m-bus) because it can read wireless devices and send needed data
through standard m-bus interface. Supports Primary addressing of attached devices from 1
to 250 (defined by user), but total devices can be up to 450. Addresses above 252 can be
read through m-bus only by secondary addressing.
