RECEIVER INTERFACES
Power
The 3510LR will operate on any DC Voltage between 10V and 32V DC. When
operational, the unit dissipates 4W of power.
The power input has reverse polarity protection. However, as the negative terminal
is also attached to the housing ground, large currents can flow to any ground
attachments made to the housing. Reverse polarity must therefore be avoided to
prevent damage to the vehicle supply.
At Voltages below 10V the unit will reset itself to prevent any data loss. At
Voltages below 6V the receiver will turn itself off.
Power is connected to the unit via a 2 metre long, black sheath, red & black 2-core
cable. The cable is terminated with a 3-pin Switchcraft EN3C3F female connector.
The connector pin layout is illustrated in Figure 4.
