BC1100 Configuration & Operation

 13

4 . 1. 2 Bit-switch 4

This switch is not used on the BC1100, and should be set to the ON state for normal 
operation.

4 . 1. 3 LVDS RTS

This switch controls the state of the LVDS RTS output. With the bit-switch set to the ON 
position, the LVDS RTS is set ON. With the bit-switch in the OFF position, the RTS control 
is set to follow the HSSI TA input.

4 . 1. 4 LVDS DTR

This switch controls the state of the LVDS DTR output. With the bit-switch set to the ON 
position, the LVDS DTR is set ON. With the switch in the OFF position, the DTR control is 
set to follow the HSSI TA input.

4 . 1. 5 LVDS TT

In order to support Contra-Directional LVDS interfaces the source of the LVDS TT output is 
selectable. With the bit-switch set to the ON position, the LVDS TT is sourced directly from 
the HSSI TT signal.

With the bit-switch in the OFF position, the incoming HSSI TT is used to latch the data into 
a buffer, from whence it is clocked out using LVDS ST to provide a Contra-Directional 
interface.

4 . 1. 6 HSSI ST

In order to support Contra-Directional interface with long cables the HSSI ST output may be 
inverted.
