Paradise RA 5785 manual RF Output Sample Port J3 Type N F, Monitor & Control Port J4 MS3112E18-32S

2.2.3 RF Output Sample Port (J3) [Type N (F)]

The RF Output Sample port, J3, is located on the bottom of the amplifier as shown in Figure 2-1. This connector provides a -40 dBc coupled sample of the amplifier’s output signal. It is a type N female connector.

2.2.4 Monitor & Control Port (J4) [MS3112E18-32S]

The M&C (Monitor and Control) connector is the primary input for controlling the amplifier and monitoring fault conditions. It is a 32-pin circular connector, MS3112E18-32S. It requires a mating connector, MS3116F18-32P, which is supplied with the unit. The pin-out for this connector is described in Table 2-2on the following page.

The Mini Compact Outdoor Amplifier has no on/off switch or circuit breaker in the AC Input path. As soon as AC power is applied to J7, the unit’s power supplies and microcontroller are enabled and the cooling fans should begin to spin. However, the internal amplifier module is disabled until the Mute Line Input (J4, Pin B) is pulled to Ground (J4, Pin V). If it is desired to have the RF enabled every time the AC input is applied, a permanent connection can be made between J4, Pin B and J4, Pin V.

2.2.4.1 Alarms on J4

A variety of alarm signals are present at the M&C connector, J4. Both Form-C relays and open collector outputs are available.

2.2.4.1.1 Summary Alarm (J4) Form C Contacts

The Summary Alarm is accessible in both Form C relay and open collector format. The Form C relay is “energized” under normal operating conditions and “de-energized” when a Fault condition exists.

2.2.4.1.2 Auxiliary Alarm (J4) Form C Contacts

The Auxiliary Alarm relay is an end user alarm that can be used to signal an alarm condition that is dependent on the state of the Auxiliary Input (J4-Pin P).

The Auxiliary Input is a contact closure to ground. When this input is pulled to ground the Auxiliary Alarm relay is energized (Normal State). When the Auxiliary Input is open circuited the Auxiliary Alarm relay is de-energized (Alarm State).

2.2.4.1.3 Open Collector Alarm Outputs (J4)

The open collector alarm outputs will require external pull-up resistors (unless connected to the Auxiliary Input). They are capable of sinking up to 20mA current at 30 VDC. The open collector outputs are pulled to ground under normal operating condi- tions and switch to high impedance state during an alarm condition.

•Auxiliary Alarm: follows state of Auxiliary Input as described above
