6-22 TOS5051A/5050A
SIGNAL I/O Specifications
Table6-1 Specifications of the SIGNAL I/O Signals
Table 6-2 SIGNAL I/O pin assignments
• * The Interlock signal input pin assignments are different from the old model
TOS5050/5051. To use the Amphenol plug for the old model to this tester, you
have to change the wiring between pins 9 and 14 to the wiring pins 1 and 9.
