Page 16: Chapter 2 Theory Of Operation
Theory of Operation Alarm Response When an alarm is triggered, the Bird Antenna & Cable Monitor turns on the alarm LED and de-asserts a TTL logic line (pulls low). In addition, depending on configuration settings, one Form C dry contact relay changes state (i.e. activates or de-activates) as a result of the VSWR alarm activating. -
Page 17: Vswr Alarm
Theory of Operation VSWR Alarm The ACMI continuously monitors forward and reflected power. From the power measurements, the VSWR is calculated and compared to the allowed maximum (default of 1.5 to 1). Based on the results of the comparison, possible actions include: ... -
Page 18: Push-To-Talk
ACMI Operation Manual Push-to-Talk The low power alarm and the VSWR alarm can falsely trigger when the transmitter is not keyed. The Push-to-Talk feature disables alarm checking for a predetermined period after the Push-to-Talk logic line is asserted. In order to prevent false alarms while monitoring for low power and high VSWR, the Push- to-Talk feature must be enabled. -
Page 19: Chapter 3 Installation
Figure 3 on page 9 When connecting the Bird ACMI to RF power, use 50 ohm coaxial cable suitable for the frequency and power level of operation. The cable connector should mate with the connector on the unit. - Page 20 ACMI Operation Manual Connect the amplifier or combiner to the Monitor’s input. Connect the antenna or feeder to the output. WARNING Do not touch the center conductor of the power monitor ports while RF power is being applied. To monitor the RF waveform, connect the forward and reflected power monitor ports to an appropriate power sensor or meter.

Installation To install a Bird Antenna Monitor in the rack mount, follow these instructions (Refer to Figure 2 on page 4 1. - Page 24 ACMI Operation Manual CAUTION Network connections require specific address and protocol information. Have a qualified IT or network professional perform the ACMI Ethernet setup. Failure to comply may result in loss of network communication or the inability to communicate with the ACMI. The setup in this section should be performed only by a person who thoroughly understands IP and network setup protocols.

Page 32: Data Log
ACMI Operation Manual Data Log The ACMI maintains a 365 day log (data log) of forward and reflected power readings and alarm conditions (low power, high power, and VSWR alarm). For each new day, the ACMI will automatically take a power reading every minute and average it with the previous minute. - Page 33 Operating Instructions Example - Comparing data from days 3-6 to days 203-206 on the same chart. You can view the days you've selected by scrolling the list to the right of the Add >> button under Day Selection. Note: The more days you view, the longer it will take to chart them.
