My visual sequencer problem

[honnjinn]

i am using serial port to link the ssc-32 to my cpu…the problem i faced was when i open the vseq,it pop out and says that cant find ssc-32 card…
from help file i notice that it asked me to choose com1 or com2 which i had tried it but still cannot detect my ssc-32…i am using a serial cable soldered 2,3 and 5th pin…i can control my motor using lynxterm and the same cable but however using vseq which i bought,it seems that i cant connect to it

Hello honnjinn,

making a RS232 cable is not so easy

on the SSC-32 side, you are right, only pins 2,3 and 5 are needed,
but the PC side is another story…

take a look at this page airborn.com.au/rs232.html

especially the part :

Wiring up something nice and simple, for instance a plain old “dumb terminal”, is just a matter of connecting Tx, Rx and Ground, right?
Usually Not. While the normal PC hardware might well run with just Tx, Rx and Ground connected, most driver software will wait forever for one of the handshaking lines to go to the correct level. Depending on the signal state it might sometimes work, other times it might not. The reliable solution is to loop back the handshake lines if they are not used

Below is another loopback site. I’ve found making the loopback connections (skipping the tx/rx lines) is generally required on win 98 machines. My xp machine doesn’t require this, but it all probably depends on the serial software.
