There are three different notations used to control relays: Backplane relay 
notation, MUX (multiplexer) channel notation, and Matrix card notation. 
To control analog backplane relays for slots with analog backplane relay 
channels, use S9BX, where: 
S: Slot number 
9: Backplane notation designation (always 9 when referencing a backplane 
relay) 
B: Bank number 
X: Analog backplane relay number 
Analog backplane relays (Bank 2 of Slot 1) examples:
