Configuration - Lantronix SCS Reference Manual

Getting Started
If your timezone is not listed, you will need to set it manually. Use the following information to set the
timezone:
A three-letter timezone abbreviation; for example, PST
The number of hours offset from UTC (Greenwich Mean Time); for example, -9:00
The time, day, and amount of any time changes (for example, daylight savings time information)
Specifying time change information is optional.
Note:
Figure 2-18 shows an example of how to set the timezone.
Local>> DEFINE SERVER TIMEZONE EST -3:00 EST 1 Mar Sun>=1 3:00 Oct lastSun 2:00
The first EST specifies that Eastern Standard Time will be used as the reference point. The second value of
-3:00 indicates that this timezone is 3 hours behind Eastern Standard Time. The third and fourth values, EST
and 1, specify that when a time change occurs the time will move forward one hour. The time change will
occur in March, denoted by Mar. The date that the time change will occur will be the Sunday (Sun) greater
than or equal to 1 (>=1), in other words, the first Sunday in the month. The 3:00 specifies that the time
change will occur at 3 o'clock.
The final three values of the command string represent the day and time when the time will revert to the
original time, in other words, when the time change will be reversed. The Oct and lastSun indicate that the
time will revert on the last Sunday in October. The time change will occur at 2:00.
2.4.4.3 Designating a Timeserver
The SCS regularly verifies and updates its setting with the designated timeserver. A timeserver is a host
which provides time of day information for nodes on a network. The SCS can communicate with either
Daytime or Network Timeserver Protocol (NTP) servers. For NTP, the SCS can periodically broadcast a
message asking for time information and wait for an NTP timeserver to reply (the Broadcast parameter),
periodically query a specific NTP timeserver (the IP ipaddress parameter), or just listen for NTP broadcasts
on the network (the Passive parameter).
To specify a timeserver, use the Set/Define IP Timeserver command.
Local>> DEFINE IP TIMESERVER DAYTIME 193.0.1.50
Local>> DEFINE IP TIMESERVER NTP PASSIVE

2.4.5 802.11 Configuration

This section applies only to the SCS200. Topics discussed in this section assume that you understand IEEE
802.11 wireless Ethernet concepts and architectures. If you do not, please refer to the IEEE 802.11 standard
or the documentation that came with your PC card or Access Point (AP).
The SCS does not support PC card hot-swapping. Any time you insert a PC card
Note:
into an SCS PC card slot, you must reboot the SCS.
