1.433 NPC-ACU-550

This page describes the device driver and the device window for the NPC SYSTEMS NEYRPIC ACU 550 via SNMP. The driver was tested with the following versions:

As the SNMP interface does not allow to read the list of stored targets on the ACU it is only possible to load a preset position or tracking using the storage numbers 0-63.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the antenna controller.

parameter description
address The SNMP address specification for the device (details below).
hasPolAxis Defines id the antenna is equipped with a pol axis drive.
readBackDelay Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized at a proved preset value which should not be changed under normal circumstances.
deviceComment An optional text entered here appears as an addition to the tooltip which is shown while the mouse is placed over a device icon in the GUI. The "\n" character sequence is translated into a newline character, splitting the text into multiple lines.

SNMP address specification

The full address consists of the following fields: aaa.bbb.ccc.ddd:pppp read-community write-community

parameter description
aaa.bbb.ccc.ddd The IP address of the device in 'dotted quad' notation. This field is mandatory.
pppp The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
read-community The SNMP read community name. This must match the read community expected by the device.
write-community The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses public as a default for read and write community string.
