public class NudamConfig
extends RS485Server

A simple configuration tool for NuDam modules. For this program to work, the NuDam module must be in the so-called DEFAULT mode, that is the DEFAULT pin (usually pin number 6) must be connected to GND.
Never connect the DEFAULT pin to any power signal.

The class opens the serial port with the current settings, as defined in the RS485Server class. It reads in the current address (which is, I'd guess always 00 in DEFAULT mode). The new address, baud rate, input range and checksum-flag are found in the KEY_NEWADDRESS, the KEY_NEWBAUD, the KEY_NEWRANGE, and the KEY_NEWCHECKSUM properties.
After opening the serial port with PropertyResources.init(), call configure() followed by AbstractSerialDriver.close() to perform the configuration. Do not forget to unplug the DEFALUT pin after configuration.

Constructor Detail

NudamConfig

public NudamConfig(Map prop)

Constructs a new NuDam configuration tool. All new parameters have default values, except the module address which must be supplied in the properties handed over. If no new address is found, or the baud-rate, respectively the input range has no recognized value, construction fails with an IllegalArgumentException.

Method Detail

configure

public void configure()
               throws IOException

Sends the configure command. Note that on set configuration the checksum flag only enters as a set/unset 6th bit (2^6) in the last byte.

Throws:

IOException

main

public static void main(String[] arg)
                 throws IOException

Reads in the new configuration from the properties file supplied as the first command line argument. The serial port is opened, the configuration command is writtn and the serial port is closed again. The new address of the module is only visible after the DEFAULT pin has been unplugged.

Throws:

IOException
