Using the SEHI100TX Hub View

NOTE

If your device Þrmware can accept four-digit year values, the Date Þeld will allow you to enter the year portion in one-, two-, or four-digit format. If you choose to enter one or two digits for the year, any value greater than or equal to 88 will be presumed to be in the 1900s; a value of 87 or less is presumed to be in the 2000s. No matter which entry format you choose, the year will still be displayed and set as a four-digit value.

If your device Þrmware cannot accept four-digit year values, the Date Þeld will allow you to enter the year portion in one- or two-digit format (with leading zeros supplied automatically for single-digit entries). No presumption is made about the century, and any two-digit year value (from 00 to 99) will be accepted.

Attempts to set the date may result in one of three different error messages. Two of these messages will indicate that the wrong number of digits has been used for the year value, and will indicate the appropriate number of digits to use for the selected device; the third message will indicate that the entered date is invalid because it is not an actual calendar date (such as 02/29 in a non-leap year, any month value greater than 12, or any day value greater than 31).
