Mini-AT User Guide

Introduction:

The Mini-AT is a full featured, stand alone, electronic gas volume corrector. Its standard mounting is on rotary,
turbine, and diaphragm meters that have a rotating shaft (instrument drive) output. The Mini-AT is also com-
patible with meters that provide high or low frequency meter pulses when the appropriate interface board is
installed. The purpose of this Operators Guide is to provide the information necessary to install and use the
Mini-AT.
The Mini-AT combines the size of Mercor Mini with the audit trail functions of the ECAT; hence, the
name Mini-AT. A PC (desktop or laptop computer) is needed to configure and download the Mini-AT
using Mini-AT Link or MasterLink32 software. Detailed information regarding the software is avail-
able through the Mini-AT Link Software Users Manual, or through the MasterLink32 help screens.
In addition to its small, sturdy case, the Mini-AT offers these and other features:
•High-performance, low power microprocessor
•Extended battery life
•Extended Audit Trail memory capacity (140+ days of hourly)
•FLASH memory (hence, no plug-in EPROMs)
•Firmware updates via serial port
•Jumper selectable Form-A or Form-C pulse output
•Jumper selectable Pulse Widths for volume pulses
•Dual serial ports (local and modem) with independent baud rate settings
•High-speed data transfers (up to 38.4 kbaud)
•On-board surge protection for serial & pulse data
•On-board connectors for a second pressure & temperature transducer
•Logging of a 2nd pressure (for monitoring pressure)
•Call-In via Alarm Pulse or AT commands
