Philips Kvaser LAPcan manual 8.1Technical Data for DRVcan, 8.2Technical Data for DRVcan

Kvaser LAPcan / LAPcan II Hardware Guide 16(19)

8.1Technical Data for DRVcan 251

Transceiver type	Philips 82c251
Current consumption	40 mA (average)
Maximum bus speed	1 Mbit/s

DRVcan 251 does not have built-in CAN bus termination.

8.2Technical Data for DRVcan 1053

Transceiver type	Philips TJA1053
Current consumption	20 mA (average)
Maximum bus speed	125 kbit/s
Built-in termination, RTH	4.7 kΩ
Built-in termination, RTL	4.7 kΩ

Note: the termination resistors RTH and RTL are optimized for bus analyzing tools. This means that they do not load the bus enough to ensure proper signal levels if there are no other "real" nodes on the bus. If you connect just two DRVcan 1053:s to a long (several meters) bus, the communication may or may not work.

8.3Technical Data for DRVcan 1054

Transceiver type	Philips TJA1054
Current consumption	20 mA (average)
Maximum bus speed	125 kbit/s
Built-in termination, RTH	4.7 kΩ
Built-in termination, RTL	Ω
	4.7 k

Note: the termination resistors RTH and RTL are optimized for bus analyzing tools. This means that they do not load the bus enough to ensure proper signal levels if there are no other "real" nodes on the bus. If you connect just two DRVcan 1054:s to a long (several meters) bus, the communication may or may not work.

8.4Technical Data for DRVcan DNopto

Transceiver type	Philips 82c251
Current consumption	80 mA (average)
Maximum bus speed	1 Mbit/s
Optocoupler type	HCPL 7101-3
Optocoupler delay	20 ns
Isolation voltage	50 V AC, 70 V DC

The transceiver in the DRVcan DNopto can be powered either from the Kvaser LAPcan, or externally by connecting a power source to pin 9 on the D-SUB.

There is no built-in CAN bus termination in the DRVcan DNopto.
