SECTION 12 REMOTE CONTROL

The MPS49 ADTS allows remote control by means of a Personal Computer, laptop or other
portable devices.
The ADWIN software is the official remote control software from D.Marchiori. It is available
for Windows and Unix platforms.
The MPS49 Remote Protocol Manual describes the communication protocol, and allows
software   developers   to   integrate   communication   with   the   ADTS   inside   custom-made
software.
For  information   about   the  protocol,   the  available   software,   or  for  assistance   during  the
development, contact your sales representative.
Remote control of the MPS49 is enabled in REMOTE mode, and is activated by pressing
the

SHIFT

+

4

keys. While in REMOTE mode, only the

HALT

key and the visualization

settings (e.g. AoA display) are active; any other key or touching the display allow to leave
the mode and return to front-panel operation.

12.1 WIRED CONNECTIONS

The MPS49, in standard configuration, is fitted with a RS232 port. A USB port is available
as option.
DMA provide a RS232 cable, and also a USB-RS232 cable, for systems that do not feature
a RS232 port.
The USB connection and the DMA USB-RS232 cables are identified by the operating
system as a USB/RS232 converters.

12.1.1 ETHERNET

The MPS49 front panel can be fitted with an Ethernet port. Communication to the ADTS is
by means of a TCP/IP connection. IP address and TCP port number can be set from the
front-panel display.

12.1.2 GPIB

An optional GPIB port allows the MPS49 to be integrated into existing Automatic Test
Equipment.
The GPIB address of the MPS49 is set from the front-panel display.

12.2 WIRELESS CONNECTIONS

The front-panel USB port allows to plug adapters that enable wireless control of the
MPS49.
To enable wireless remote control, plug the adapter, wait for 5 seconds and then press the

SHIFT

+

4

keys. The MPS49 will allow the Operator to select the available connection

option.

12.2.1 BLUETOOTH

The MPS49 can be controlled by means of a “Serial Port Profile” (SPP) Bluetooth
connection.

1. Connect the Bluetooth adapter, wait for 5 seconds and select Bluetooth REMOTE

mode.
