PCAN-TJA AND PCAN-AU

Bus converter module
 
Bus converters enable CAN High Speed components (based on Philips PCA82C250, PCA82C251 and TJA1050 transceivers), such as PCAN-USB or a PCAN-PCI card, to be connected to Low Speed CAN bus systems. The PCAN-AU5790 has been developed for the Philips AU5790 transceiver and the PCAN-TJA1054 has been developed for the PCA82C252, TJA1053 and TJA1054 transceivers.

The bus converter receives its 5 V supply via pin 1 of the 9-pin D-Sub connector. A slide switch allows the termination resistors on the TJA1054 interface to be switched between 0.56 and 5.66 kOhm. An error LED displays the error output from the Low Speed CAN transceiver
(TJA 1054). The AU5790 can be switched between the various operating modes by means of a slide switch mounted on one side.

Note: The TJA1054 Low Speed transceiver always runs in normal operating mode. It cannot be switched to Sleep mode or Standby mode.
