PIN卡配置
* Applicable to e Series, i Series, and the retrofit systems • For the GR2280 and GR2281 testers 11 pin boards can be used if the AFTM is not used. • The GR2285e and the GR2289e are both extended performance systems and work at 10 MHz. All other systems operate at 5 MHz except Stinger systems, which are analog only.

Pin卡基本结构
Pin card type: Combo I, Combo II, HDC etc. For TS128L can use Ultra 128L/124 card, max 30pcs pin card. MUX ration is 2X16 or 2X8, 16 or 32 real Driver/Sensor are configured into 8 or 16 groups of 2 each. Each group maps into 8 or 16 nails, therefore, only 2 of 16 nails can be utilized simultaneously.
INSTRUCTOR NOTE: Position 3 is the D/S reference, PIO Fixture ID, PIO Relay Drivers & PIO TTL D/S. These resource is used for digital test. Contains power supplies 1 - 6.
RTC: Run Time Controller, BUS interface for the analog subsystem directs & coordinates pin board activities; data transfers between cpu and the digital subsystem;
