External Driver Electrical Requirements
The Xtium2-CXP allows user selected (software programmable) input switching points to support
differential (RS-422) input signals and single ended (TTL, 12V or 24V) input signals. The following
table defines the external signal voltage requirements from the driver circuits connected to the
Xtium external inputs.
