INSTRUMENT COMMISSIONING Upon switch-on, the display shows in sequence: - instrument model (e.g.: ); - followed by the software code (e.g.: ); - program type: (base); - followed by the software version (e.g.: ); - followed by the hardware code (e.g.: ); - serial number (e.g.: ); Setting the parameters related to: - serial communication (see section SERIAL COMMUNICATION SETTING) - WiFi communication (see section WIFI COMMUNICATION SETTING) PROGRAMMING OF SYSTEM PARAMETERS From the weight display, press simultaneously keys MENU and ESC to access the parameter setting. MENU/ENTER: to enter a menu/confirm the data entry. : to modify the displayed figure or menu item. : to select a new figure or modify the displayed menu item. ESC: to cancel and return to the previous menu. WIFI COMMUNICATION SETTING The instrument can operate as access point or client. WARNING: both operating modes (access point and client) use communication port 10001. In point-to-point communication, an instrument configured as access point generates the network to which the instrument configured as client connects itself. If the client is correctly connected to the network, it shows the message LINKED, otherwise it shows the message READY!; the access point always shows the message READY!. When the device connected to the client communicates and the one connected to the access point replies, on both displays the message TX<-->RX appears. - 4 -
For the connection you can use both a web-socket and a virtualization software of the serial ports on ethernet (see section CONNECTION TO PC BY VIRTUAL WIFI/ETHERNET PORT). If the connection to the network fails, make sure that the distance between the instruments does not exceed 100 meters in open air and/or ensure that no shield or noise affect the antennas. It is recommended to place the client instrument in an easily accessible position, in case an operator needs to check any communication problems. OPERATION AS CLIENT connecting the instrument to an existing network + - : enables the operation of the instrument as a client in a CLIENT/SERVER or CLIENT/ACCESS POINT network. - : network name (it must consist of only numbers; e.g.: 123456). - : instrument IP address. - : access point IP address. - : login password of the access point; if no password is required, set 0. Any password must be an 8-digit number that starts with two zeros; e.g.: 00123456 (only the underlined digits can be displayed and modified by the instrument). In order to apply the changes, turn the instrument off, wait for 10 seconds and turn it back on. OPERATION AS ACCSS POINT connecting other devices to the network created by the instrument + - : network name (it must consist of only numbers; e.g.: 123456). - : access point IP address. - : login password of the access point; in order to leave the connection open set 000000. Any password must be an 8-digit number that starts with two zeros; e.g.: 00123456 (only the underlined digits can be displayed and modified by the instrument). In order to apply the changes, turn the instrument off, wait for 10 seconds and turn it back on. - 5 -

CONNECTION TO PC BY VIRTUAL WIFI/ETHERNET PORT A PC, by a virtual serial port, can be connected to the MODWF via WiFi. To install the virtual COM port, use the CPR Manager included in the supply: - run the file CPR.exe on the CD; - add a serial port; - set an IP address (host) and a TCP port (10001); - save. Use the just created virtual COM port to communicate with the instrument connected to the MODWF using the selected protocol. Alternatively connect to the MODWF using a socket (e.g.: Winsock) on port 10001. - 10 -
ENERGY SAVING + - : energy saving mode disabled (default). - : the display enters energy saving mode after two minutes of keypad inactivity; by pressing a key normal operations will be restored. - (only if relays are not in use): the display, the WiFi module and the load cells enter energy saving mode after two minutes of keypad, serial ports or WiFi module inactivity; normal operations will be restored by pressing a key or when data are received by the serial ports. The energy saving mode is activated also if an outgoing monodirectional protocol is set. (e.g.: or ). Note: the energy saving options turn off the devices involved. ALARMS AND MESSAGES CONCERNING THE WIFI MODULE The bottom line of the instrument display shows the WiFi module status and the battery option. : : READY!: LINKED: TX<-->RX: the instrument is storing and checking the entered settings; wait until the message has disappeared to proceed. during the settings storage and check some error occurred; verify and enter the last settings again. the instrument is ready to comunicate. the instrument configured as client is connected to the access point. the device connected to the instrument is communicating via WiFi. - 11 -
