Safety Instructions 5 (18)
2 Safety Instructions
2.1 Information on EMC
Risk of interference to radio and television if used in office or home environment!
Make sure, that DIN rail is connected to the ground.
Use exclusively included accessories. Use exclusively shielded cables.
Make sure, that the shield of the CAN cable is connected.
If necessary, enlarge distance between source of interference (e.g. motors, frequency inverter) or
drain of interference and device to avoid interference.
2.2 General Safety Instructions
►Protect product from moisture and humidity.
►Protect product from too high or too low temperature (see Technical Data, p. 12).
►Protect product from fire.
►Do not paint the product.
►Do not modify or disassemble the product. Service must be carried out by HMS Industrial
Networks.
►Store products in dry and dust-free place.
2.3 Intended Use
The devices are used to establish a physical coupling of two or more segments of a CAN or CAN
FD bus system. It is possible to implement tree or star topologies, as well as long drop lines. With
a galvanically isolated repeater network segments can be electrically decoupled.
The devices cannot be used to extend a CAN/CAN FD system because in terms of signal the
repeater corresponds to a line with delay time.

Configuration 7 (18)
5 Configuration
To operate the CAN repeater no software installation is required. The CAN repeater is configured
via DIP switches (1).
Fig. 1 DIP switches
5.1 Configuring the Lock Time
The CAN transceiver transmits data and receives these transmitted data again after a certain
delay, the so-called loop delay. For example, if the transceiver transmits a dominant bit and after
that a recessive bit, the transceiver only sees the recessive bit in its receive output after the loop
delay. The size of the loop delay depends on several factors, like for example the number of CAN
nodes in the network. The higher the capacity load is, the higher is the loop delay. To avoid bit
errors caused by this delay, the configured lock time must be higher then the loop delay.
►Use a screwdriver or similar tool to set the DIP switches.
►Observe, that the setting depends on the bit rate and the capacitive load of the network
(the higher the capacity load, the higher the value).
►Configure the lock time with DIP switches 1 and 2.
►Observe the following reference values:
– for networks with less than 32 nodes the lock time is about 200 ns
– for networks between 32 and 64 nodes the lock time is about 400 ns
– for networks with more than 64 nodes the lock time is about 800 ns and with this
setting the bit rate is limited to maximal 500 kbit/s

Off Off 200 ns (default)
On Off 400 ns

On On 1600 ns

Configuration 8 (18)
5.2 Extending the Recessive Bit
Due to the internal structure the CAN transceiver shortens recessive bits on the network, and
thus dominant bits are extended. At high bit rates this might cause errors. To extend the
recessive bits may improve the error rate, as the bits then are closer to their nominal value on
the network. If the recessive bits are extended with the DIP switches, the extension is made
independently of the bit rate, also at low bit rates.
►Use a screwdriver or similar tool to set the DIP switches.
►Extend the recessive bit with DIP switches 3 and 4.
Valid Combinations
DIP switch 3 DIP switch 4 Recessive bit extension
Off Off 0 ns (default)
On Off 10 ns
Off On 20 ns
On On 30 ns
