Section 3-5
3-5 Setting the Conditions of Communications with the Host
by Using the Memory Switches
The communications between the NT20S and a PC/Host are called the host com-
munications.
The NT20S models can be connected to the host using the following communica-
tion methods.
NT20S-ST121-EV3 :Host link or NT link (both direct connection)
NT20S-ST122-V1 :C200H direct communication (direct connection)
NT20S-ST128 :RS-232C communication (command control)
With NT20S-ST121-V3, the host link, NT link (1:1), and NT link (1:N) communica-
tion methods are set with memory switches. Other settings such as baud rate and
automatic resetting of communication are also set with memory switches.
This section describes the communications condition settings by using the
memory switches.
Memory Switches The NT20S has the memory areas used to store the PC connection method, com-
munications conditions, system settings, etc. which can be used as the switches
and called the “memory switches”. Since the memory switches use the flash
memory, the stored data can be held even when the power supply is turned OFF.
Setting Functions and the Memory Switch Menu
The memory switches can be set easily by using the memory switch menu in the
System Menu.
The following settings can be made with the memory switches. Refer to the subse-
quent pages and Section 3-8 Various System Settings for the details of each set-
ting and function.
