Connecting External Devices to the NGC Instrument

Tip: If you do not plan to connect the C-96 autosampler or other external

devices to the NGC instrument you can skip this section.

This section explains how to connect the signal import module (SIM) to the NGC

instrument, and how to connect exter

nal devices to the SIM.

 For information about connecting the C-96 autosampler to the SIM, see

Appendix C, Connecting the C-96 Autosampler to NGC Systems on

page 165.

 For information about connecting the SIM to an NGC instrument, see

Connecting the SIM to the NGC Instrument on page 67.

 For information about connecting other external devices to the SIM, see

Connecting External Devices to the SIM on page 69. Next, see the chapter

System Controls in the NGC Chromatography Systems and ChromLab

Softwar

e User Guide to enable the components.

 For information about installing and setting up an external device, see its

installation documentation.

Controlling Programmed Functions via Transistor-to-Transistor

Logic

You can control a function of an external device or receive function information from

a device via the SIM. Using the SIM’s transistor-to-transistor logic (TTL), the NGC

instrument can mark when a function occurred on an external device through the

SIM’s DIGITAL IN port, or send commands to an external device through its DIGITAL

OUT port.

For example, you can connect a C-96 autosampler to the SIM enabling NGC

systems to pr

ovide automated, accurate, and reproducible sample injections.

Connecting the autosampler to the SIM’s DIGITAL OUT and DIGITAL IN ports

enables the NGC instrument to inform the autosampler when to begin its injection

cycle and to mark when the autosampler injects a sample.
