Connect Transmitter Antenna
1. Carefully screw the transmitter antenna onto the transmitter. Turn the antenna clockwise, being careful to avoid cross-threading
the antenna. The antenna must be snug and flat against the case.

Configure NTP Time (Optional)

The transmitter has the option to be configured to use NTP time. If the system will use NTP as its time source, complete the
following configuration procedures.
Overview
To use NTP time, the transmitter is required to be connected to a wired Ethernet network, its switch settings 1 and 2 must be set to
the up position, and optionally can be configured to use an alternate NTP time source if the factory-default NIST time source will not
be used.
The transmitter NTP settings are accessed and configured from a Web browser on a computer that is on the same Local Area
Network (LAN) as the transmitter. If you need assistance, contact your IT department.
NOTE:
Prior to configuring the NTP time source, please be aware the IP address of an NTP server and transmitter is required
to complete this configuration. Also, before beginning this procedure, set the computer to use a static IP address.
Transmitter Factory Default Settings

Pre-Configured NTP Time Source: By default, when configured for NTP time, the transmitter is programmed from the
l
factory to obtain the NTP time from the National Institute of Standards and Technology. According to the NIST, they
provide a public service by outputting one of two official time sources by the United States. Readings from the clocks of
the NIST contribute to world time, called Coordinated Universal Time (UTC). The time maintained by NIST should never
differ by more than 0.000 0001 seconds from UTC. For more information, please visit:
