This page describes the device driver and the device window for the MCL MT3300, MT3400, MT4000 and MT4400 power amplifiers. Low Power TWT amplifiers. This driver was tested with 750W MT4430
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 operational parameters (BEAM-ON/STANDBY, RF ON/OFF)
--- Displays meter readings like output power and TWT specific measurements.
--- 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 to make the software talk to the Amplifier.
| parameter | description |
|---|---|
| address | The device address (decimal). The factory default is 49 |
| lowLimit | The low output power limit. A value of 0 disables the limit check |
| highLimit | The high output power limit. A value of 0 disables the limit check |
| Serial | Remember to set the line parameters for the serial interface connected to the TWTA. The factory default of the HPA is 9600,E,7,1 . |
Serial interface settings
You have to configure the the serial interface on the front panel of the HPA. If you want to use RS232 you have to use the "Computer" interface not the "Remote" interface.
Additionally you have to set the jumpers behind the front panel to enable RS232. For details please refer to the user manual of the HPA.
Hint: For testing RS232 communication you can use pin 6(rx), 9(tx) and 5(ground) of J5 Computer interface if the jumper is set to RS485. If set the jumper for RS232, you can use the documented pins of J5.
