DVC80 J1939 Bridge

DVC80, J1939 Bridge Expansion Module

The DVC80 (J1939 Bridge) is a unique CAN Bus gateway. The DVC80 is designed for a range of applications, including but not limited to agriculture, construction, forestry, mining, material handling, refuse and transportation. This module was built to serve as a data link between DVC Control System and J1939 CAN Bus systems. It uses the DVC CAN Bus protocol and SAE J1939 standard protocol to receive, filter and re-transmit messages. The data gathered in these messages can then be incorporated into the DVC control system, allowing for a proactive system control approach as well as the typical reactive system control approach. An RS-232 interface allows for connection to on-board computers or laptops. This port is used for setup, real-time diagnostics and data logging. A +5Vdc reference is available for supplying power to external sensors. The module operating temperature is -40C to +80C. The enclosure is a rugged, encapsulated, plastic enclosure designed for harsh environments.

FEATURES

· Network Link: Provides a data link between the DVC and J1939 networks. Passes information requested by the DVC10 (Master Module) while blocking all other network traffic.

· Computer Interface (RS-232): Used to setup the module (baud-rate/node address), monitor J1939 activity and perform real-time diagnostics.

· Diagnostic LED’s: Show Module Status (MS), Network Status (NS) and J1939 activity.

· Software Upgradeable: Flash based application can be re-programmed through the serial port without disassembly.

· Rugged encapsulated enclosure withstands harsh environments commonly found in mobile applications.

· Rugged power supply operates over the full range 8.0Vdc to 32Vdc with reverse polarity protection and transient protection up to 1.5K Watts Peak Pulse Power Dissipation.

DVC LOADER/MONITOR SOFTWARE FEATURES

A. Local RS-232 Connection (connected directly to the DVC80).

1. Set the DVC CAN Bus baud rate.

2. Set the module MAC ID.

3. Monitor the J1939 messages passed to the DVC CAN Bus.

4. Select an additional ten J1939 messages to be monitored.

5. Take a data log of all J1939 messages being monitored.

B. Remote RS-232 connection (connected to the DVC10 RS-232 port).

1. Monitor the J1939 messages passed to the DVC CAN Bus.

COMMUNICATION PORTS

A. The DVC80 has three communication ports:

1. DVC Can Bus 2.0B – This port is used to interface to the DVC CAN Bus. A DeviceNet protocol is used.

2. J1939 CAN Bus 2.0B – This port is used to interface to J1939 CAN Bus. Connecting a jumper wire between P12-C2 and P12-C3 will add a 120-ohm termination resistor between CAN_H and CAN_L.

3. RS-232 serial port – This port is used for setting MAC ID, setting Baud Rate, monitoring, diagnostics and data logging.

POWER SUPPLY

A. The DVC80 Power Input has the following features:

1. Range: +8.0Vdc to +32Vdc

2. Reverse polarity protection and transient protection up to 1.5K Watts Peak Pulse Power Dissipation

3. Power is supplied to the module through P12 (not the Can Bus).

4. +POWER IN: Main power input.

5. PWR COM: This is the DVC80 main common (usually connects to chassis ground).

B. +5Vdc Reference

1. +5Vdc output ( +/- 5%)

2. Maximum current output; 150ma (current consumption of over 300ma may cause permanent output failure).

3. Protected from shorting to PWR COM.

4. Connecting this output to greater than +5Vdc will void warranty and possibly cause module failure.

INDICATORS

A. Module Status (MS) (Qty 1) (R/G)

1. Off – There is no power applied to the Module.

2. On green – The module is operating in a normal condition.

3. Flashing green – Device in standby state. May need commissioning.

4. Flashing red – Recoverable Fault.

5. On red – Module has an unrecoverable fault.

6. Flashing Red/Green – Device is in self-test.

B. Network Status (NS) (Qty 1) (R/G)

1. Off - Device in not on-line.

2. Flashing green – Device in on-line but has not established connection to other nodes.

3. On green – Device in on-line and has established connection to other nodes.

4. Flashing red – One or more connections are in a timed-out state.

5. On red – The device has detected an error that has rendered it incapable of communicating on the network.

C. J1939 Status (Qty 1) (R/G)

1. Off – No message activity.

2. Randomly flashing green – message activity.

3. Flashing red – Loss of communication to the J1939 Bus.
