So I got LinuxCNC to start up without errors. I have connected 8i20 drive to 7i43 card. 1) But I do not see it in "Show HAL config" (I expect it to appear there, if sserial module finds it): http://www.linuxcnc.org/docs/devel/html/man/man9/hostmot2.9.html#8i20 Based on that I understand that communication between sserial and 8i20 is not happening. I should mention that between 8i20 and 7i43 is my diy ttl <--> rs422 converter (I am aware of existence of 7i44 card, but since I only want to test, how 8i20 would perform with my servo motors, I thought that building such a convertor would be cheaper). That converter is based on SN75179 chip (very first scheme here): http://www.datasheetarchive.com/dl/Datasheets-37/DSA-720721.pdf Based on firmware's PIN file, there are following sserial pins on P3 connector: 21 34 IOPort SSerial 0 RXData1 (In) 23 35 IOPort SSerial 0 RXData2 (In) 25 36 IOPort SSerial 0 TXData1 (Out) 27 37 IOPort SSerial 0 TXEn1 (Out) 29 38 IOPort SSerial 0 TXData2 (Out) 31 39 IOPort SSerial 0 TXEn2 (Out) I have connected RXData1 and TXData1 to my converter, all the remaining pins are not connected anywhere. Is this correct? How can I test the communication between 7i43 and 8i29 cards, to see, if that convertor is actually working? On 8i20 card 4 LEDs are shining: Pwr Lv status Iso pwr Fault 2) Even more, in INI file I have: [HOSTMOT2] DRIVER=hm2_7i43 BOARD=7i43 CONFIG="firmware=hm2/7i43-4/BOSSVSS.BIT num_encoders=6 sserial_port_0=00" But in "Show HAL config" I see not only 6 encoders, but also 2 pwmgens and 5 stepgens. Can anyone suggest me, where did they come from? Is there a chance for any 8i20 user (preferrably together with 7i43) to share some insights, how to set it up? I would really appreciate related parts of config files.
