NX100 Pre-installation Manual Planning control/monitor connectionsIssue 3.2 2017-03-31 Page 8-5Remote inputsYou can connect to up to 16 remote inputs, which allow you to remotely control various operationalcharacteristics of the transmitter. Each input is mapped to a control that is user defined. See Table 8.1on page 8-5 for a list of input options and their functional descriptions. See Table 8.2 on page 8-6 forthe associated input terminals and control switches (see “Backup control switches” on page 8-8) onthe remote interface PWB (A11A4). Refer to the NX100 Operations and Maintenance Manual forinstructions on changing the remote input settings, including which setting is assigned to the inputpin and which logic is required to change (activate, enable, etc.) the setting.Unless otherwise noted these inputs are only accepted by the transmitter if the remote/local status isset to remote. That setting can only be made by a local user using the front panel AUI.The external remote input circuits interface with the transmitter via the remote interface PWB andthen with opto couplers on the control/interface PWB. The opto couplers buffer and isolate theexternal circuits and prevent any unwanted transients from affecting transmitter operation whileremote control is selected on the transmitter.Table 8.1: Remote Inputs - Selection OptionsRemote Input FunctionRF On Same as pressing the AUI RF On button. Tells the transmitter to provide RF power if possible.Provide an active pulse to select.RF Off Same as pressing the AUI RF Off button. Tells the transmitter to disable RF power. Provide anactive pulse to select.Reset Causes a system reset. Provide an active pulse to select.Increase RF Power Increases the power level of the current mode. Send an active pulse to increase the powerslightly, or send a signal of greater duration to continue increasing power.Decrease RF Power Decreases the power level of the current mode. Send an active pulse to decrease the powerslightly, or send a signal of greater duration to continue decreasing power.Exciter A Select Causes a changeover to select exciter A as the active exciter. Provide an active pulse to select.Exciter B Select Causes a changeover to select exciter B as the active exciter. Provide an active pulse to select.Auto Changeover Enables or disables automatic exciter changeover. Provide an active pulse to toggle betweenselecting automatic or manual.Scheduler On/Off Enables or disables the automatic mode scheduler. Provide an active pulse to toggle betweenselecting automatic or manual.Max Power LockoutSelectSelects the associated power lockout limit (1 to 8) as active.
