Table 2 – XJLink2-CFM J12 Main Connector Pinout
4. Recommended Signal Routing
Table 3 shows a recommended signal routing when using all 18 signals. In this example, one XJLink2-
CFM is used with three extender boards and a multi-section ribbon cable that has 6 connectors. Sixteen
of the XJLink2-CFM’s signals are routed to the direct pins on the Teradyne MFAB, and the remaining two
signals are connected to multiplexed pins. The XJLink2-CFM is placed in slot 2, with extender boards in
the remaining three positions.

20 RELAY1
Input from the Teradyne system that controls a relay to isolate the DIR
signals from the testbed. 0 V connects J9 pins 7 & 5 to this connector
23 DIR4 Signal to/from J9 pin 7 when RELAY1 is at 0 V. Otherwise: open-circuit
24 RELAY2
Input from the Teradyne system that controls a relay to isolate the DIR
signals from the testbed. 0 V connects J9 pins 3 & 1 to this connector
27 DIR3 Signal to/from J9 pin 5 when RELAY1 is at 0 V. Otherwise: open-circuit
31 DIR2 Signal to/from J9 pin 3 when RELAY2 is at 0 V. Otherwise: open-circuit
35 DIR3 Signal to/from J9 pin 1 when RELAY2 is at 0 V. Otherwise: open-circuit
