Service mode
Service interface
The MA 30/31 is provided with the service interface for commissioning the
reading stations in the network. This interface can be accessed by removing
the housing cover on the MA 30/31. It has a 9-pin SUB-D connector.
Connection
Thus, you can connect a PC or terminal to the MA 30/31 via the serial inter-
face RS 232/V.24 and parameterise the network. The connection is made
using a crossed RS 232 connection cable that establishes the RxD, TxD and
GND connections. A hardware handshake via RTS. CTS is not supported at
the service interface.

Service DIP switch
In order to activate the service mode,
DIP switch 3
must be set to the "ON"
position. The switch must always be in this position when commands are to
be sent from a PC to the MA 30/31 via the service interface. If the switch is
set to "OFF", data can be listened to passively but cannot be sent to the net-
work.
Attention!
Activating the service mode interrupts the connection to the host computer,
i.e. the serial communication with the network takes place exclusively
through the service interface.
Notice!
The network can also be parameterised via the host interface. For commis-
sioning, however, parameterisation via a PC is considerably more conven-
ient, especially when the configuration software CONFIG 3.0 from Leuze
electronic is used.
