ERI (Enhanced Remote Interface)
ERI replaces the AGP Remote Interface that is used in the HP
1090/1040/1050/1100 HPLC systems and Agilent 1100/1200/1200 Infinity
HPLC modules. All new 1200 Infinity II products using the FUSION core

All common TTL circuits operate with a 5 V power supply. A TTL signal is defined as "low"
or L when between 0 V and 0.8 V and "high" or H when between 2.0 V and 5.0 V (with
respect to the ground terminal).

Pin Signal Description
1 START REQUEST (L) Request to start injection cycle (for example, by start key on
any module). Receiver is the autosampler.
2 STOP (L) Request to reach system ready state as soon as possible (for
example, stop run, abort or finish and stop injection). Receiver is
any module performing run-time controlled activities.
3 READY (H) System is ready for next analysis. Receiver is any sequence
controller.
4 POWER ON (H) All modules connected to system are switched on. Receiver is
any module relying on operation of others.
5 Not used
6 SHUT DOWN (L) System has serious problem (for example, leak: stops pump).
Receiver is any module capable to reduce safety risk.
7 START (L) Request to start run / timetable. Receiver is any module
performing run-time controlled activities.
8 PREPARE (L) Request to prepare for analysis (for example, calibration,
detector lamp on). Receiver is any module performing
pre-analysis activities.
