RE: The later four ports of IP-Octal-232 could not work.

Dear Li Gang,

 

Is your VIPC616 the standard board, or do you have the -01 option?  I believe that the standard board does not support one interrupt, which is used by the last slot (D).  At the APS we use the VIPC616_01, and I think it works fine with IP-Octal in any slot.

 

You can convert a standard VIPC616 to the -01 option yourself.  You need to wire-wrap some pins, and replace 2 PAL chips.  Marty Smith at the APS can provide you with the details on how to do this.

Hi Everyone;

   I am using the IP-Octal 232 and VIPC616 carrier board, with drvAscii/drvSerial/tyGSOctal. There are four slots(A ,B ,C ,D ) in one VIPC616 and eight ports(a ,b ,c ,d ,e ,f ,g ,h ) in each IP-Octal 232. The communication is ok between IP-Octal 232 and other devices, when the IP-Octal 232 is put into slot A, or slot B ,or slot C of VIPC616. When the IP-Octal 232  is put into slot D of the VIPC616, The later ports(e ,f ,g ,h ) of the IP-Octal 232 doesn't work again, however,the first four ports(a ,b ,c ,d ) of IP-Octal 232 work well. I have exchange several IP-Octal 232 and VIPC616 respectively, the same errors will occur again.

   Is anybody could do help me? any adivce ia appreciated! Thanks in advance.
