Description

SerCAN is a protocol converter between CAN and devices with RS232 interfaces. SerCAN allows the connection of devices with serial interfaces to CAN based systems, e.g measuring devices, barcode scanners and handheld terminals. SerCAN obtains its potential through the use of a 32 bit microcontroller with 48MHz clock. High speed processing and low latencies allow the use with high data rates and busloads. SerCAN covers the typical applications for protocol conversions. If SerCAN is used as universal CAN interface, the generation of any desired CAN message under control of the serial device is the most favourable solution. In this case, a fixed, error detecting protocol is used at the serial interface. This protocol is open documented and implemented as default firmware. Filtering of incoming CAN messages is possible and configurable by the user. Should there be a demand to change the serial protocol, an application development kit is available, which allows the implementation of custom specific firmware.

Technical Data

Layout and Connection

The connection to the CAN bus is achieved via pluggable terminals. Besides the CAN signals the clamps also carry the supply voltage for SerCAN-ARM7. The terminals are connected according the following table:

PinNameFunction
1+24VSupply voltage
2, 3, 6-8GNDGround
4CAN_HCAN data line (dominant high)
5CAN_LCAN data line (dominant low)

The Sub-D 9 male plug is connected according the following table:

PinNameFunction
2RxDReceive data line
3TxDTransmit data line
5GNDGround
7RTSRequest-to-Send control line
8CTSClear-to-Send control line
