DGC-2020ES Communication
4 • Communication
DGC-2020ES communication ports include a mini-B USB port, CAN terminals, and provisions for an
optional Remote Display Panel. The following paragraphs describe the DGC-2020ES communication
ports in detail.
Caution
This product contains one or more nonvolatile memory devices.
Nonvolatile memory is used to store information (such as settings) that
needs to be preserved when the product is power-cycled or otherwise
restarted. Established nonvolatile memory technologies have a physical
limit on the number of times they can be erased and written. In this
product, the limit is 100,000 erase/write cycles. During product
application, consideration should be given to communications, logic, and
other factors that may cause frequent/repeated writes of settings or other
information that is retained by the product. Applications that result in such
frequent/repeated writes may reduce the useable product life and result in
loss of information and/or product inoperability.
USB
The rear-panel, mini-B USB port enables local communication with a PC running BESTCOMSPlus
®
software. The DGC-2020ES is connected to a PC using a standard USB cable. BESTCOMSPlus is a
Windows
®
-based communication software package that is supplied with the DGC-2020ES. A detailed
description of BESTCOMSPlus is provided in the BESTCOMSPlus chapter.
CAN
A Controller Area Network (CAN) is a standard interface that enables communication between multiple
controllers on a common network using a standard message protocol. DGC-2020ES controllers have a
CAN interface that supports the SAE J1939 protocol and the MTU protocol.
Applications using an engine-driven generator set controlled by a DGC-2020ES may also have an Engine
Control Unit (ECU). The CAN interface allows the ECU and DGC-2020ES to communicate. The ECU
reports operating information to the DGC-2020ES through the CAN interface. Operating parameters and
diagnostic information, if supported by the ECU, are decoded and displayed for monitoring.
The primary use of the CAN interface is to obtain engine operating parameters for monitoring speed,
coolant temperature, oil pressure, coolant level, and engine hours without the need for direct connection
to individual senders. Table 4-1 lists the ECU parameters and Table 4-2 lists the engine configuration
parameters supported by the DGC-2020ES CAN interface. These parameters are transmitted via the
CAN interface at preset intervals. See the column labeled Update Rate in Table 4-1 for transmission
rates.
CAN interface connections are made at 13 (CAN H), 14 (CAN L), and 15 (SHIELD).
