Connection Of Peripherals To The Can Bus - Optimus COMPACT Installation And Operating Instructions Manual

5. CONNECTION OF PERIPHERALS TO THE CAN BUS

The COMPACT device communicates with the COMPACT-E and IF-7P4/0E units via a CAN bus. The data flow rate between the
COMPACT device and the COMPACT-E and IF-7P4/0E expansion units is 500 kbit/s (default rate).
With the other CAN peripherals in the installation (MD-30C, ME-200C, NS-CAN...) and thanks to an internal speed adapter
incorporated in the COMPACT unit, the transmission speed is 33.333 kbit/s. This lower speed makes it possible to reach greater
distances in the connection between the peripherals and the COMPACT
unit. The adapter also makes it possible to galvanically isolate the
COMPACT from the equipment in the installation, protecting it from
possible wiring problems in the installation. To communicate with these
peripherals, the transmission speed of the COMPACT unit must be set to
33.333 kbit/s, as explained in section 5.1.
In installations where COMPACT-E or IF-7P4/0E units coincide on the
same CAN bus with other CAN peripherals (MD-30C, ME-200C, NS-
CAN...) it is necessary to install the external CAN-AV model speed
adapter (code A465AV) to match the transmission speed between units.
