GridConnect CAN USB-232 Operation & User’s Manual

2.12.2 set timestamp 2.13 CAN Timeout Commands It is possible, under heavy CAN bus loads or faulty CAN bus, to place the unit in a state where no more input parsing from the COM port can occur due to the internal buffers being full and the CAN TX not being able to proceed. Under this condition, a config command cannot be processed. This is to ensure that no CAN messages are lost while waiting for the CAN bus to become available. In order to prevent this, a timeout parameter can be specified that will ensure additional input parsing can occur at th ...

The CAN USB-232 can also be configured to force immediate transmission upon detection of specific user- configured bytes in the data stream (CR or LF, for example). It also supports defining and sending of WAKE messages to support CAN networks that go into SLEEP mode. See more detail in help options under ‘set can vc’ 2.8.1 The ‘XMIT’ and ‘RCEV’ Identifiers When configuring the CAN USB-232 for Virtual Circuit operation, two identifiers must be specified in order for the virtual circuit to work correctly. These two identifiers are referr ...

2-43 2.10.2 Setting Up Message Filters To use message filtering, each filter used must be enabled and then configured as to the type of filtering that is desired. All of these parameters are configured during the configuration process. A filter is configured in the following order: 1) Enable the filter 2) Specify if standard or extended and if single ID or ID range. Once all configuration parameters have been saved and the CAN USB-232 enters the normal operating mode, the new filter settings will become active and will be applied to each received CAN mes ...

The SJW parameter controls the maximum allowable adjustment to the sampling point. This allows for a CAN node to adjust its sampling point when it determines that the sample point would be too early or too late. By setting the SJW field to a large number, the CAN USB-232 can work with other nodes with a large variation is bus oscillator tolerances. The value can range from 1 to 4. 2.7 CAN Command Mode In the command mode, the CAN USB-232 is capable of sending and receiving arbitrary CAN messages via the use of ASCII or Binary formatted message strin ...

2.7.2.1 Examples Example #1 :S123N12345678; This message string indicates a 11-bit identifier whose value is $123, is normal, and has four data bytes: $12 $34 $56 and $78. Example #2 :XF00DN; This message string indicates a 29-bit identifier whose value is $F00D, is normal, and has zero data bytes. 2.7.3 RTR CAN Message A RTR CAN message consists of the type (11-bit or 29-bit), identifier, length, does not have any data bytes, and is encoded as follows: RTR CAN Message Syntax : ; The first character ,‘:’, is for ...
