CHAPTER 1. OVERVIEW
1. GENERAL
This is a specification of the on-line data communication via RS-232
interface.
It enables the ECR to perform on-line communication.
For on-line data communication a ECR can be connected to a host
computer.
We support mainly the following functions.
a) The function of ONLINE
1) Down load of ECR data (ECR 1 PC)
2) Up load of ECR data (ECR 3 PC)
3) RJE (Remote job entry) function (ECR 1 PC)
CHAPTER 2. SYSTEM
CONFIGURATION
1. GENERAL
Online data communication is allowed always.
2. ONLINE DATA COMMUNICATION
In this machine, the type of data communication is “Direct connection”
only.
(a) Direct connection
