Arbiter Systems

With the proper settings, the SEL-3610 Port Server, SEL-3620 Ethernet Security Gateway, and

SEL-3622 Security Gateway are all capable of synchronization with these clocks. This

application guide outlines the steps necessary to set up time synchronization between an Arbiter

clock and any of these SEL devices. It also describes how to test the connection to ensure proper

operation.

If the Arbiter clock you are using has a GPS lock (e.g. has an attached antenna and has found

satellites), skip to Set Up IRIG-B Settings (after consulting your Arbiter instruction manual to

ensure that proper settings are in place).

To set the time on an Arbiter satellite clock for local testing without a GPS lock (e.g., the clock

has poor reception or no antenna), you need local access to the device. If the device has a front-

panel LCD, ensure that the main EIA-232 port is set up in INTERROGATE mode. Connect a

null modem cable from the main EIA-232 port to a local computer. Use a terminal program, such

as Tera Term or PuTTY, and connect to the device.

Once the device is connected, use the set receiver time command to locally set the time on the

clock. This time is only used if there is no GPS lock. The command, yyyy:mm:dd:hh:mmTS,

and the format are described in Table 1. Note that if the time is set locally, it is cleared when the

device restarts.

This sets the Coordinated Universal Time (UTC) of the device. You should now be able to set up

the local time offsets on the Arbiter clock. Note that these local time changes will not show up on

Page 1 SEL-3622 Security Gateway are all capable of synchronization with these clocks. This application guide outlines the steps necessary to set up time synchronization between an Arbiter clock and any of these SEL devices. It also describes how to test the connection to ensure proper operation.
Page 2 SEL device even if the Arbiter clock is set to send local IRIG-B time; these changes will send during the IEEE 1344 extension of the time code. The SEL device will use the delivered UTC time, so setting the Arbiter clock to send local IRIG-B time has no effect. To set up the SEL devices for the time zone of your choice, consult their corresponding instruction manuals.
Page 3 ONCLUSION This application guide describes a process for testing an Arbiter clock with SEL devices. When set as shown in this application guide, the Arbiter clock properly provides IRIG-B time to the SEL devices.
