Specs: I need more than 2 channels of Digital Input. Can the 2700 support this?

Yes, the Model 2700 can support dozens of channels of digital input. While the 2700 mainframe has two digital inputs for triggering a measurement or scanning sequence, additional digital input lines can be created by using the Analog Input channels. Simply set the HI / LO limits on each channel to TTL levels, and configure the 2700 to look for the Pass / Fail flags while scanning.
