(Relay Control Line) Pin 2 is hot.  Pin 4 is gnd.  2 shorts to 4 on Tx.

... probably.  The long term problem is that the SB-200's relays are 
slower than a TS-450.  The long term fix is to install high speed 
switching in the SB-200.  See Fig. 7B on my Web site -  or the Jan. 1994 
issue of *QST*.
