9.103 ChinaSuncom-9293S3-ACU

This page describes the device driver and the device window for the China Suncom 9293S3 Antenna Controller.

The driver controls the ACU via Modbus/TCP, in the VLC Setup a ChinaSuncom-9293S3-ACU device must be attached to an interface / ports with the ACU's IP address and port 502.

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 .

--- The first parameter page displays the antenna pointing and lets you move the antenna to a particular pointing. The page contains all parameters of te ACU managed by the driver.
--- The faults page.
--- The device info page.
--- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set for a proper operation of the ACU.

parameter	description
address	Doesn't care, may be left empty. Modbus/TCP doesn't use device addresses.
azLoLimit azHiLimit elLoLimit elHiLimit plLoLimit plHiLimit	Sets the valid range of the three pointing angles. You should set these to the values of the soft limit as set in the ACU itself. Unfortunately there is no way to read these values via Modbus.

Remarks

The operation of the Suncom ACU is based on a number operation modes. You first have to select the operation mode, then you can enter parameters or command specific to this mode.

To move the antenna to given pointing angles, set 'operation mode' to 'PRESET' and then enter the target angles.
To preset the antenna for a given satellite number, set 'operation mode' to 'SATPRESET' then enter the satellite number and click 'GO'
To start steptrack, set 'operation mode' to 'STEPTRACK' and then select the steptrack mode (OFF/ON).
To stop the antenna, click 'STOP'
'operation mode' may be set to 'MANUAL', but the driver offers no buttons to jog the antenna. The response would be too slow via Modbus for a satisfying user experience.
For machine controlled operation, pointing angles may be commanded in any operation mode. The driver automatically switched the ACU to 'PRESET' mode if it receives a pointing angle command.
