EV2 - GC Ready Inputs

EV2 has the choice between TTL or CC type GC Ready signals. These can be TTL high or TTL Low or CC open or CC closed.

TTL - Transistor to Transistor Logic (Voltage change to trigger a signal; 0 - 5 vdc)

Agilent and Thermo GCs fall under TTL GC Ready signals.

CC - Contact Closure (Dry Contact with a ground: essentially completing or opening a circuit)

Shimadzu and Scion GCs fall under CC GC Ready Signals.
