DC Power Connection (Plug-In Terminal Block)

The TRACER 64x0 can operate from a supply between 21 and 60 VDC, with either polarity referenced to ground, and consumes less than 25 W. Power supplies should be able to provide up to 25 W at the selected voltage. Current required (in amps) is determined by dividing the power consumed (in watts) by the applied voltage (in volts). For example, at 48 V, TRACER 64x0 would draw approximately 0.52 A

(25 W/48 V). Table 8 shows the DC power connection pinout.

Applying power to the radio without a 50Ω load attached to the antenna interface can damage the system. Verify the 50Ω load is attached before powering the radio.

When using a power source that has the positive terminal or the negative terminal connected to earth ground, the grounded terminal must be attached to the TRACER 64x0 power input that is identified with the ground symbol. Otherwise, equipment damage will occur. When using a power source that has neither terminal connected with earth ground (floating), either terminal may be connected to the TRACER 64x0 power input identified with the ground symbol.

Fuse

The fuse holder, accessible from the rear panel of the TRACER 64x0, accepts a generic 2 A, 250 V, 2-inch slow-blo fuse.

Alarm Contacts (Plug-In Terminal Block)

An RF link down condition is indicated with both normally open (NO) and normally closed (NC) alarm contacts on the rear panel of the TRACER 64x0 system. In normal operation, the NC contact is electrically connected to the common contact (COM) and the NO contact is isolated. When the RF link drops, the NC contact becomes isolated and the NO is electrically connected to COM. This allows RF down conditions to be reported to external alarm monitoring systems. Table 9 provides the alarm contact pinout.

Antenna Interface (N-Type Connector)

The ANTENNA interface (N-type connector) connects to the customer-supplied antenna using standard antenna feedline cable. When determining the cable specifications for your application, refer to Section 2, Microwave Path Engineering Basics (System Losses (L) on page 21) for a discussion on cable length and
