This means that serial port Bmust be used for communications with the host.Communication Condition Settings for Bar Code ReadersSetting ItemFunctionSetting OptionsPageData bitsSets the bit length for the data bits.7* or 8 bitsPage 145Stop bitsSets the stop bit length for the data.1 or 2* bitsPage 145Parity bitSets the parity bit for the data.None, odd, even*Page 145Baud rateSets the baud rate for the bar code reader4800, 9600*, or 19200bpsPage 145Input methodSets the method for confirming data when it is input to a character string input field.Manual: The data is confirmed with a touch switch.

The “Calendar Check” displays the most recent clock data read from thehost.Reference:S The NT21’s clock function is not a counter. This function just displays the mostrecent clock data read from the host.S The clock data is initialized to the default settings when the NT21 is turned OFF.The default date and time is 01/01/00 00:00:00. (The clock data is not backedup even if a battery is installed.)S After the NT21 is turned ON, the default date and time (01/01/00 00:00:00) willbe displayed until communications are established with the host and the clockdata is read properly from the host.S The clock function does not strictly check the date and day of the week settings.S The clock data cannot be set from the NT21’s System Menu or the NT SupportTool.S Numeral memory table entries 247 to 253 are reserved for the clock function(read-only).
Clock data can be read from these addresses in the numeralmemory table during operation and displayed.147Section 6-11System MaintenanceDisplay clock data by following the menu operations from the System Menu asshown below.Select Maintenance Mode.Select Calendar Check.Press QuitThe NT21 will return to the MAINTENANCEMODE MENU screen.148Section 6-11System Maintenance6-11-2 Checking the PT Setting StatusThe direct connection settings of the NT21 screen data, and the settings for serial port A and serial port B, can be checked.Screen Configuration and Display ContentsThere are four different screens that show the PT setting status.

Only the screens for which the display history screen attribute has beenset in advance are processed by this function.The record data can be displayed using an operation from the System Menu.This section explains how to display the display history record data recorded inthe NT21.Note that there are two display methods: sort by occurrence (display time order)and sort by frequency (order of number of times displayed).Reference:S Install an optional battery in the NT21 when using the display history recordfunction.S When a battery is not installed or the battery fails, the contents of the historyrecord will be unpredictable when the NT21 is turned OFF and will be initialized.S Time stamps will be recorded with the history records using clock data read bythe NT21 from the host.
