The Lionel Y connector cable is for having a serial to go to the computer and a connection to go to the Powermaster Bridge. That's the only use for it. The end that goes to the Powermaster Bridge is a totally different set of pin connections than the normal serial pin out.

cjack, the "Y" supplied with the Legacy system is more commonly used to hook a TMCC Base to the Legacy Base, hence the label "Command Base" on the male 9-pin connector.  The connections at the 9-pin "Command Base" connector are still pins 2, 3 and 5.  Those pins just feed into different pins at the male Legacy Base - pins 4, 1 and 5.

 

Perhaps you are referring to a different "Y" cable?
