1-1-4 Setting Switches
Use the switches to change the communications conditions for communica-
tions with the host computer. Before using the E5ZN, match the settings to the
host.
Operate the switches under the following conditions only.
• The power supply must be turned OFF. The settings will be enabled only
when the power is turned ON again.
• To change the switch setting, use a flat-blade screwdriver and turn the
switch to the required position.
Unit Number A unit number is set for each Temperature Controller to identify the Tempera-
ture Controllers connected to the host and to an E5ZN-SDL Setting Display
Unit.
The unit number is set in hexadecimal.
The switch settings are 0 to F, which correspond to unit numbers 00 to 15.
↑ Default
Set a different unit number for each Temperature Controller when more than
one E5ZN Temperature Controller is connected for RS-485 communications.
Communications cannot be performed if the same unit number is used more
than once in one system.
Baud Rate Match the E5ZN Temperature Controller baud rate to the host baud rate.
