Software Selectable Line Interface Modes

The Serial Line Interface utilizes Sipex devices SP507 (on Revision A and B cards) or SP508
(on Revision C and proceeding cards). Refer to the data sheet for these devices for all electrical
characteristics of the interface.
The Line Interface Mode is software selectable for each Channel. The following Modes are
available:
