DC Power Interface

The DC power interface is comprised of the DC power inputs and a control signal as summarized in Table

7. The three +5V Inputs and three 0V supply returns are used to supply DC power to the 9601 and ensure

that enough current can be drawn across the connector without the 9601 malfunctioning during transmit

due to lack of current supply. Note that all six pins should be connected.

The DC power supply requirements for the 9601 are summarized in Table 8 below. Note that these

requirements apply to DC power measured at the 9601 multi-interface connector input and not at the

output of the power supply. Long power supply cables can cause a voltage drop sufficient to cause the

voltage to be out of specification at the physical power supply input to the 9601.
