X-I/O Module Overview
• The X-I/O module requires X64 Xcelera-CL PX4 board driver version 1.00 (or later) and Sapera
LT version 5.30 (or later).
• Occupies an adjacent slot to the X64 Xcelera-CL PX4 Full. Slot can be either PCI-32 or PCI-
64—no PCI signals or power are used.
• Connects to the X64 Xcelera-CL PX4 via a 16 pin flat ribbon cable. J23 on X-I/O to J6 on
X64 Xcelera-CL PX4.
• The X-I/O signals supplement the external signal I/O available on the main board. The two sets
of I/O are independent of each other.
• X-I/O provides 8 TTL outputs software selectable as NPN (current sink) or PNP (source driver)
type drivers. See "
TTL Output in NPN Mode: Electrical Details" on
page 107 and "TTL Output
in PNP Mode: Electrical Details" on page 108.
• X-I/O provides 2 opto-coupled inputs. See "Opto-coupled Input: Electrical Details"
on page 109.
• X-I/O provides 6 TTL level inputs with software selectable transition point. See "TTL Input
Electrical Details" on
page 109.
• X-I/O provides both +5 volt and +12 volt power output pins on the DB37, where power comes
directly from the host system power supply.
• Onboard flash memory to store user defined power up I/O states.
