Thank you for purchasing an A2B Electronics product. The MyM-3T is a revolutionary solution 
for reception and modulation of satellite transmitted TV-content into an analogue format suited 
for small SMATV networks where cost efficiency and high quality is required.
The MyM-3T receives DVB-S and DVB-S2 transmissions.

The MyM-3T unit is delivered with hardware and software that supports DVB-S/S2 reception, 
MPEG2/MPEG4 decoding, DSB RF modulation with NICAM or A2 audio, IP control and 
management. 
The MyM-3T can be upgraded for enhanced functionality by software upgrades.
Software upgrades are available from A2B Electronics web site.

address: 192.168.0.20. 
First time installation requires that you set a 
static IP address on your computer. For 
example set your PC to IP address: 
192.168.0.19 and Net mask: 255.255.255.0

The MyM-3T can be installed either as a stand alone unit directly on the wall or by the use of a 
dedicated MyM Security Wall Mount (part number 702800.10). The MyM Security Wall Mount 
secures both the MyM and CAM-modules with a locking function to avoid loss of CAM’s and 
smart cards in public places.

Before connecting power to the MyM-3T, make sure that all other connections have been made. A 
coaxial cable of good quality with an F-connector should be connected  to the Antenna  input and 
another one from the RF output to the SMATV network. 
Connect the power supply and make all necessary settings as described in section 4 and 5.
