Antenna assembly
Warning
In order to be compliant with CE recommendation, the user is not use other radio equipments (antenna) than the ones
provided by Itron or the optional external antenna reference no RFMASTERMAGANT.
RF Master is equipped with a BNC type connector. The antenna is mounted and locked by turning it turn clock wise.
Connection to the hand held terminal
Use a specific cable to connect the hand held terminal to the RF Master.
The RF Master female plug is a 5 pins binder type.
Plug pin out
- 1: DTR
- 2: Rx

3:
Tx
- 4: +Vdd
- 5: GND
The maximal cable length is 1.5 meter.
Operating the RF Master
Once all the above connections are done, run the radio reading software on the hand held terminal.
Thanks to the belt clip located on the rear side of the RF Master, it is easy to fix on a belt, on a pocket side or on the hand
held belt.
LED understanding
Three diodes are located on the RF Master front side. They can be used to visualize the Communication status between
the RF Master and the meter interface unit.
Red: Hand held terminal - RF Master communication
Green:
radio
emission
Yellow:
radio
reception
Timing
Red light: handheld to RF Master communication.
Green light: radio communication from RF Master to meter interface unit.
Yellow light: meter interface unit answer receiving.
If no answer is received from the meter interface unit, the yellow LED will not switch on.
The red LED then the green one will light again to indicate an other try (number of retries is defined by the reading
software).
