The viewer can use the following communication types :

RS232 Connection

To establish a RS232 connection, a serial communication cable is required.  This cable can be ordered from Ranger Instruments (part number : 0220).  It has the following pin connections:

2 3
3 2
5 5

This cable should be directly connected between the RS232 port on the WE2111 to a COMx port on the PC.

Click on the " Connect" button on the toolbar to establish the connection.  A window appears which allows the RS232 link to be configured.  The following information must be given:

When this information is correct, click OK to connect.  If the connection is established, the weight appears on the display page of the viewer.  If a connection cannot be established, an error message appears.  If an error occurs, check that the cables are plugged in properly and the communication setup is correct and retry.

RS422/RS485 Connection

To establish a RS422/RS485 connection, the following equipment is required:

Connecting the RS485 Bus
  1. The RS232 to RS485 converter should be plugged into a COM port on the PC.  The 12V power for this converter needs to be connected.
  2. The RS485X crossover cable should be connected between the converter and a WE2111 (either serial port).
  3. If more than one WE2111 is being connected:
    1. Each additional WE2111 should be connected using a RS485 cable between either serial port and the unused serial port on the previous WE2111.
    2. Ensure that each WE2111 has a unique address and is configured to use RS485.  See also How To : Configure WE2111 Networking to check and set WE2111 network settings.
Click on the " Connect" button on the toolbar to establish the connection.  A window appears which allows the link to be configured.  The following information must be given: When this information is correct, click OK to connect.  If the connection is established, the weight appears on the display page of the viewer.  If a connection cannot be established, an error message appears.  If an error occurs, check that the cables are plugged in properly and the communication setup is correct and retry.

To view a different WE2111 on the network, click connect the " Connect" button again and specify the address.
