Setting Conditions for Communications with Host by Using Memory Switches Section 6-7
• To quit the unit number/communications speed setting screen without
confirming the unit number/communications speed settings, press the
Abort touch switch. The NT631/NT631C will return to the memory switch
setting screen (4/4) with the previous settings still in effect.
Reference: • Unit numbers are numbers assigned to each PT when multiple PTs are
connected to one host, so that the host can identify the individual PTs.
The units numbers that can be set differ according to the host model, as
follows.
• C200HE(-ZE):
Unit numbers 0 to 3 (maximum of 4 PTs per host port)
• C200HG(-ZE), C200HX(-ZE):
Unit numbers 0 to 7 (maximum of 8 PTs per host port)
When making the settings, make sure there is no duplication of unit numbers
among PTs.
On completion of unit number setting, the NT631/NT631C returns to the
memory switch setting screen (4/4).
To set other memory switches, select the relevant screen using the ] (next
screen) or [ ] (previous screen) touch switch, then make the setting.
• To confirm the settings and quit the memory switch setting screen, press
the Quit touch switch. The settings made last will be set and the NT631/
NT631C will return to the MAINTENANCE MODE MENU screen.
• To quit the memory switch setting screen without confirming the settings,
press the Abort touch switch. The NT631/NT631C will return to the MAIN-
TENANCE MODE MENU screen with the previous settings still in effect.
In this example, serial port A is used.
Press Quit.

Press the Set touch switch to the right of the

Speed touch switch to display the
communications speed, standard or 115.2-

setting determines which method of 1:N
NT Link is used.)
The setting option changes each time the
touch switch is pressed. In this example,
serial port A is used for a standard 1:N NT
Link.
