6.1.1 M2T Connectors
There are four connectors located on the M2T unit as shown in Figure 2. They
are for interfacing the RF, SD/HD SDI Video, ASI out, audio, component and
composite video and Control signals. There are also frequency select switches
located on the side of the transmitter also shown in Figure 2

6.1.1.1 RF Output, Ant Port
The M2T uses a female SMA connector for its ‘RF Output’ port. The
antenna is attached here.
Note: Transmitters should not be powered on without a load
attached to the RF output. Doing so could damage the internal
Power Amplifier (PA).

6.1.1.2 SD/HD SDI
A female BNC connector is provided for SD-SDI or HD-SDI video input
streams. The input bit rate is 270 Mbps for SD and 1.485 Gbps for HD.

6.1.1.3 ASI Out
A female BNC connector is provided for DVB-ASI Transport Stream
Output. The output bit rate is 270 Mbps. This transport stream does not
include the SI tables, User-Data, or AES encryption which is added later
in the processing chain.

6.1.1.4 Frequency Select Switches
There are four external rotary switches mounted into the chassis of the
M2T (reference Figure 2). They are used to control RF frequency
selection. Frequency selection can also be controlled through GMS
control software; see section 6. The most significant switch (SW100)
represents 1000MHz (0-9) units, the second switch (SW101) represents
100MHz (0-9) units, the third switch (SW102) represents 10MHz (0-9)
units and the fourth switch (SW103) represents 1MHz (0-9) units. Hence
the highest switch selection can be 9999MHz and the lowest is
0000MHz. For example with the switches in the following positions, the
frequency will read 2025MHz.
