The settings made last will be set and the NT21 will return tothe MAINTENANCE MODE MENU screen.If the combination of settings for serial port A and serial port B is not allowed, anerror message (indicating that the protocol settings are incorrect) will be displayed when the Quit touch switch is pressed. In this case, correct the settingsto a combination that is allowed.• To quit the memory switch setting screen without confirming the settings, pressthe Abort touch switch.

The NT21 will returnto 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 unit numbers that can be set differ according to the host model, as follows.S C200HE(-ZE):Unit numbers 0 to 3 (maximum of 4 PTs per host port)S C200HG(-ZE), C200HX(-ZE), CS1G/H(-H), CJ1G, CQM1H:Unit numbers 0 to 7 (maximum of 8 PTs per host port)When making the settings, make sure there is no duplication of unit numbersamong PTs.On completion of unit number/baud rate setting the NT21 returns to the memoryswitch setting screen (4/4).To set other memory switches, select the relevant screen using the [ ] (nextscreen) or [ ] (previous screen) touch switch, then make the setting.• To confirm the settings and quit the memory switch setting screen, press theQuit touch switch.
