1 - Introduction
The World Time Solutions MC500 is a Network Time Server with an
Ethernet port and an RS-232 serial output. The MC500 obtains time
information from a connected antenna and uses this data to service
NTP time requests from multiple devices on a TCP/IP network. The
MC500 also provides RS-232 level time and date information and
PPS (Pulse Per Second) data.
The MC500 is based around World Time Solutions proprietary
software for enhanced security.
1.1 - Quick start guide
The following list of procedures can be used for rapid installation of
the MC500:
• Install the MC500 into a 19” equipment rack or on a suitable
surface (see section 2.1).
• Install and connect a suitable antenna system to one of the
remote synchronisation inputs (see section 2.2).
• Connect the MC500 to a suitable 100-240 VAC mains power
supply via the supplied power adapter (see section 2.3).
• Enter the required network address settings or set the MC500 for
DHCP operation (see section 3).
• Select the local time zone (see section 4.1 & appendix D).
• Connect the MC500 to your TCP/IP Ethernet network via a
network switch or hub (see section 2.4).
The following optional procedure may also be performed:
• If required, congure the RS-232 serial time and date / PPS
(Pulse Per Second) outputs.
• If required, connect the RS-232 serial port to a third-party device.
1.2 - Package contents
The MC500 is supplied with the following component parts:
• MC500 Network Time Server
• Power adapter
• CAT5 patch & RS-232 serial cables
• User manual
What is NTP?
Network Time Protocol (NTP)
enables the synchronisation
of computer clocks across data
networks. It was originally
proposed in the early 1980s
and has been continually
updated and used ever since.
Further information may be
found at the home of the NTP
project:

Section 1: Introduction
1.4 - LCD time and status displays
In normal operation, the liquid crystal display (LCD) shows the local
time and date and synchronisation status. The MC500 also has three
status display screens accessible via the ‘STATUS’ switch. The status
display screens show basic information from the connected antenna
systems and the status of the network interface.

2 - Installing the MC500
The MC500 is supplied in a robust metal case suitable for mounting
into an industry standard 19” rack. The system is supplied with an
external power adapter and also requires a connection to your local
area network and connection to a compatible World Time Solutions
Time Receiver System.
System setup should be performed using the front panel switches.
2.1 - Physical installation
The MC500 has been designed for installation into an industry
standard 19” rack. The unit is 1U (44mm - 1.75”) high.
2.2 - Remote synchronisation input connections
The MC500 has two remote synchronisation inputs for connection
to compatible World Time Solutions Time Receiver systems. The
MC500 is designed to operate with either one or two antenna systems
connected. In installations using two antenna systems, the MC500
uses the second antenna as a live backup system.
2.2.1 - Installing the antenna system
The antenna system/s should be installed as specied in the
accompanying installation guide.
2.2.2 - Connecting the antenna system to the MC500
The antenna system/s should be connected to one of the Remote
Synchronisation Inputs using the supplied cable. Connections should
be made as shown in the installation guide accompanying the antenna
system. Please also refer to the antenna installation guide for details
of how the cable may be extended.

Section 2: Installing the MC500
2.2.3 - Antenna system setup and status
The MC500 monitors the status of any connected antennae and
automatically selects the most stable and accurate as a synchronisation
reference source.
All compatible World Time Solutions Time Receiver systems
incorporate setup information into data messages sent to the MC500.
This setup information is used by the MC500 to perform any required
setup changes automatically. Therefore, new or different antenna
systems can be connected to the MC500 in the future without any
programming changes by the user.
Detailed information regarding antenna synchronisation status may
be obtained via the sync status screens (see section 1.4.2).
2.3 - Power connection
The MC500 is supplied with an external power adapter. The power
adapter should be connected to the MC500 before being connected
to a local mains power supply.
2.4 - Local area network connection
PLEASE NOTE: In order to prevent possible network setup conicts, it is
recommended that the MC500 is not connected to the network before the Network
Setup Procedure in section 3 has been completed.
The MC500 should be connected to an Ethernet switch/hub on a
TCP/IP network. The MC500 has a 10BASE-T/100BASE-TX auto-
sensing Ethernet port and should be connected to the network using
the supplied CAT5 patch cable (or similar).
2.5 - RS-232 output
The MC500 has an RS-232 data output providing user programmable
serial time and date messages and PPS (Pulse Per Second) data.
Please refer to section 4 for connection and setup details.
2.6 - Earth connection
To ensure compliance with the relevant Electromagnetic Compatibility,
Radio disturbance and Immunity standards, the MC500 should be
connected to a suitable earthing point using the rear Earth binding
post.
MC500 - Network Time Server - User Manual - Version 1.56
3 - Network setup
The Ethernet port enables the MC500 to be connected to a TCP/IP
network via an Ethernet switch or hub (see section 2.4).
The network interface may be programmed to operate with DHCP
enabled or disabled. When DHCP operation is enabled, the MC500
attempts to obtain network address settings automatically from a
DHCP server on the network. With DHCP disabled, network address
settings are manually entered into the unit.
3.1 - How to enter the network setup menu
The network setup menu can be accessed using the front panel
switches as shown in the graphic below:
3.2 - Changing the DHCP setting
As shown in the graphic on the following page, with the MC500 in the
network setup menu and the DHCP option screen displayed, pressing
either the ‘UP’ or ‘DOWN’ switches will toggle the DHCP mode. When
the correct mode has been selected, pressing the ‘ENTER’ switch will
forward on through the remaining network setup menu options.
If DHCP is enabled, the remaining network setup screens will show
the IP settings obtained from the DHCP server. If the MC500 has
not yet obtained a DHCP lease, the IP address, subnet and gateway
screens will show ‘---.---.---.---’ in place of a valid network address.
The status of the network connection may be conrmed by displaying
the network status screen (see section 1.4.3).
From this point, the network setup menu may be exited by a further
four presses of the ‘ENTER’ switch.
What is DHCP?
Dynamic Host Conguration
Protocol (DHCP) enables the
automatic assignment of IP
address settings on a TCP/IP
network.
Upon connection to a
TCP/IP network, a client
device congured for DHCP
operation communicates with
the DHCP server and obtains
an IP address lease.
The DHCP protocol is dened
in RFC 2131, available for
download from:
