Exiting the LCD Emulator
l
Operation procedure
(1) Click on the Exit command in the Connect menu.
The dialog box asking if you wish to exit the LCD Emulator appears.

(2) Click the Yes button.
This disconnects communication with the analyzer, exiting the LCD Emulator.

Limitation on the Number of Users to be Connected Simultaneously
The analyzer cannot communicate with multiple LCD Emulators at the same time. If a user
attempts to make a communication connection with a particular analyzer using an LCD Emulator
while another user is already communicating with that analyzer using an LCD Emulator, the
second connection cannot be established. In this case, a message box appears indicating the IP
address of the currently connected PC.

Forced Connection
Forced connection is a connection means to establish a communication connection even if the
analyzer concerned is communicating by Ethernet with the Ethernet LCD Emulator on another
PC.
For example, assume that PC1 with the IP address XXX.XXX.XXX.100 has started an Ethernet
LCD Emulator and has been communicating with an analyzer. In this case, if PC2 with the IP
address XXX.XXX.XXX.101 starts an Ethernet LCD Emulator to make a forced connection
with that analyzer, connection with PC1 is terminated and a dialog box stating “Communication
is disconnected due to forced connection from XXX.XXX.XXX.101” appears on PC1. Then
communication between PC2 and the analyzer concerned will be started. (Last priority)
Moreover, if another PC has started an LCD Emulator to make a serial connection and is
conducting serial communication with an analyzer unit’s LCD, forced connection is still possible.
(In this case, proceeding with serial communication will be interrupted.)
