Winco DGC-2020 - Manual (Page 76)

Modem Communication
If connecting to the DGC-2020 through a telephone line, select USB via Serial RS232, Modem, and enter
Phone Number.
To select the correct COM Port, open Windows  Device Manager and expand the
Modems branch. Right-click on the modem name and choose Properties. Open the Advanced tab to view
the COM port.
Ethernet Communication
Communication with the DGC-2020 can be made through an optional LSM-2020 (Load Share Module). In
order to use the Ethernet capabilities of the LSM-2020, the network settings in the LSM-2020 must first be
configured. The settings are configured through the DGC-2020 and sent to the LSM-2020 over the
CANbus interface. The following procedure is used to configure LSM-2020 network settings and connect
to the DGC-2020 through Ethernet via an LSM-2020.
1. Navigate to the Settings, System Params, System Settings, LSM Setup screen on the front panel HMI
and verify that the LSM-2020 is enabled with the correct CANbus address so that the DGC-2020 and
LSM-2020 are properly linked together. If a USB connection to the DGC-2020 is active, the LSM-
2020 enable setting and CANbus address can be found by using the Settings Explorer in
BESTCOMSPlus to open the System Parameters, System Settings tree branch as shown in Figure
4-20. The DGC-2020 will annunciate a pre-alarm if the LSM-2020 is not connected properly when it is
enabled. If the connection is valid, the network settings of the LSM-2020 can be configured through
the USB interface of the DGC-2020.
2. Connect to the DGC-2020 through the USB port as described under USB Communication. Select
Configure, Ethernet from the File pull-down menu. If the LSM-2020 is connected properly, the
Configure Ethernet Port screen shown in Figure 4-9 will appear.
Figure 4-9. Configure Ethernet Port
Configurable
options include:
IP Address: Internet Protocol Address to be used by the LSM-2020.
Default Gateway: Default host to send data destined for a host not on the network subnet.
Subnet Mask: Mask used to determine the range of the current network subnet.
Use DHCP: Automatically configures IP Address, Default Gateway, and Subnet Mask
via DHCP. This can be used only if the Ethernet network has a properly
configured DHCP server running. The LSM-2020 does not act as a
DHCP server.
The values for these options should be obtained from the site administrator if the LSM-2020 is
intended to share the network with other devices. If the LSM-2020 is operating on an isolated
network, the IP address may be chosen from one of the following ranges as listed in IETF publication
RFC 1918, Address Allocation for Private Networks.
