1. Introduction Time Machines Precision Clocks (TMPCs) provide an accurate synchronized time source when you absolutely can't afford a time shift. TMPCs use Power over Ethernet (PoE) and Simple Network Time Protocol (SNTP) to make installation and setup as clean and simple as possible. Connecting the clock to a PoE enabled Local Area Network (LAN) Ethernet drop is all that needs to be done.
2. Initial Setup 2.1 PoE TMPCs require connection to a PoE enabled LAN. There are two ways of going about this, one is to have a PoE switch and the other is to have a PoE injector. PoE injectors are offered through Time Machines as an accessory.
2.3.2 Rack Mounting 1. Attach an ear to each side of the clock. 2. Attach clock to rack. Illustration 1: Attaching Rack Mounting Ears 2.3.3 Dual Clock Mount Bracket Materials needed; 1. Two Time Machine Clocks of the same size 2.
the cables can run through the bracket and down into the backside of each clock. 2. At the ends of the clocks, leave the screws out about 1/4” so that they can be inserted into the key holes on the Dual Mount Bracket. 3.
3. Configuration 3.1 Web Page – Default password is “tmachine” All TMPC parameters are accessed on the configuration web page. The page can be accessed by pointing any web browser at the IP address of the TMPC. The initial IP address can be found by using the push button (double-click) located on the back of the TMPC.
Illustration 5: Parameters Page (Part 2) 3.1.1 Network By default the network parameters are setup up using DHCP. In order to set static values, uncheck the DHCP check box and enter new values in the address fields. If the values aren't changed the current addresses will be kept.
have a predetermined offset except for CUSTOM. 3.1.2.3 Custom Time Zone If CUSTOM is selected for the Time Zone then this field is editable. Set the desired custom offset by using the drop down menus to select hours, minutes and (+/-). 3.1.2.4 SNTP Resync Period The SNTP Resync Period entry sets the period between SNTP requests.
3.1.3.2 Fixed Day The Fixed Day check box indicates whether or not DST occurs on a specific date. For example, if DST started on March 1 of every year, the Fixed Day box would need to be checked. The Fixed Day box is important in that it changes how the Start and Stop parameters function.
NOTE* If a constant display of the date is desired, the “Time” field can be set to 0 seconds, and the “Date” field can be set to any value greater than 0. 3.1.4.5 Date Offset This field is used to select a forward offset, in days, to the current date. If the “Date Offset” value is selected as 0, the current date will be displayed.
3.1.6.1 External Connection External connection will require the user to make a connection from the clock's internal relay to an external system. The Time Machine Clock alarm closes an internal relay. Relay closure presents 12Vdc (500mA max) on the Normally Open (NO) output. Position 1, of the relay connector. Illustration 6: Connector for Relay The Common and Normally Closed (NC) carry 12Vdc during normal operation.
3.1.7 Brightness This parameter allow the user to control the brightness of the display. There are three settings that are selectable. DEFAULT, the brightest setting • MEDIUM • LOW, the lowest setting. • 3.2 Push Button 3.2.1 Changing the Time Zone Using the push button provides a quick way to set the time zone with out having to access the configuration web page.
4. Troubleshooting 4.1 Flashing Seconds There are two instances when the seconds (6 digit clock) and the AM/PM dots will flash to indicate a problem. 4.1.1 Lost Link If the seconds and the AM/PM dots are flashing it is possible that the link was lost, check to make sure everything is connected properly at both ends of the cable.
