1200T Series Analog Clock Displays Manual
Revision 1.2 1200T - 1
1. OVERVIEW
The 1200T Series Analog Clock Displays take master and slave clock technology to new levels of
convenience and excellence. The clocks are microprocessor controlled and employ separate direct drive
motors for each hand. This means that, as well as being able to set the time almost instantaneously, the
new displays are also silent in operation. The hands of the clocks can be programmed to move in sweep
mode or in steps.
Each clock can be programmed for automatic Daylight Saving Time adjustment, as well as for any time
zone offset using a laptop computer. It is then only necessary to supply the clock system with Universal
Coordinated Time (UTC) from the master clock. Daylight Saving Time changes will be automatic, as will
adjustments for different time zones.
Each clock can be used as a master or slave clock. When used as a slave clock, it reads SMPTE linear
timecode (LTC) from a master clock. When used as a master, it generates LTC for distribution to other
slave clocks. In fact, any clock in the chain can generate timecode as soon as it loses timecode input from
the master. The system is therefore extremely robust and reliable.
When the +T option is added, the 1200T series clocks can lock to time disctributed as Network Time
Prototcol (NTP) over Ethernet.
The problems of power distribution have also been considerably simplified. With other clock products, it is
necessary to install power outlets wherever clocks are to be located. The 1200T system slave clocks may
be powered from the Ethernet cable that distributes both power and NTP time. The clocks may also be
powered locally using the AC to 12VDC adapter provided.
Internal crystal oscillators ensure that the clocks will continue to operate in the absence of input timecode.
Internal battery backup ensures that each clock will continue to keep time in the absence of timecode and
power. When power resumes, the hands will immediately reset to the correct time.
The 1200T series clock displays are offered in two sizes. Backlighting is available for all models.

1.1. Compatibility with Original 1200 Series Analog Clocks
This manual is applicable only to the 1200T Series hardware. This 1200T Series hardware can be
distinquished from the original 1200 Series hardware by inspecting the rear panel of the unit. 1200T
series units are fitted with an RJ45 connector which is used to provide Power over Ethernet, SNMP and
NTP. The original 1200 series units do not have this RJ45 connector. This is the easiest way to tell the
difference between the two types of hardware. Please contact the Evertz service department to get
manual for the 1200 Series clocks.
Although this cursory examination reveals some obvious differences in the units, there are other
differences, which may not be as obvious. Series 2 hardware supports most but not all of the features of
the Series 1 hardware.
Features supported in the 1200 series hardware, that are not supported in the
1200T Series hardware are highlighted in special notes such as this throughout
this manual.

2. INSTALLATION
The 1200 series clocks have keyhole slots for mounting. They have a 4 pin connector for timecode input
and output. They have a power jack for 12 VDC input and there is a 12 VDC adapter supplied which is
installed in a slot in the rear panel. This allows the clock to run on 12 VDC, 100240 VAC or to receive
power from a Power over Ethernet power sourcing device. There is a DB-9 connector for RS-232
communications from a PC.

If you wish to control the 1200T series clock using the VistaLINK®software, it is
important to set up the IP address before the clock is installed. This is done
using the com port and a computer. See section 7.

1200T Series Analog Clock Displays Manual
1200T - 4 Revision 1.2
2.1. TIMECODE INPUTS AND OUTPUTS
There is a terminal block at the rear of the clock that can contain the time code inputs and outputs.
IN+, IN- These two input pins are for connecting SMPTE/EBU linear timecode (LTC) to the clock.
OUT+, OUT-These two output pins are for connecting LTC to other clocks.
The LTC output can be configured to operate as a loop through from the input LTC, for
connection to downstream clocks, or an output of the local clock time.
The 1200T Series clocks are not compatible with the power over LTC feature of
the 1200 Series analog clocks. As such they can not be powered from an
upstream 1200 Series clock, neither can they power downstream 1200 Series
clocks. The LTC inputs of the 1200T Series clocks will not be damaged if they are
connected to powered LTC outputs from a 1200 Series clock.
2.2. ETHERNET CONNECTIONS
The 1200T clocks are designed to be used with either 10Base-T (10 Mbps) or 100Base-TX (100 Mbps)
also known as Fast Ethernet, twisted pair Ethernet cabling systems. When connecting for 10Base-T
systems, category 3, 4, or 5 UTP cable as well as EIA/TIA – 568 100 
STP cab
connecting for 100Base-TX systems, category 5 UTP cable is required. The cable must be “straight
through” with a RJ-45 connector.
The straight-through RJ-45 cable can be purchased or can be constructed using the pinout information in
Figure 2-3. A colour code wiring table is provided in Figure 2-3 for the current RJ 45 standards (AT&T
258A or EIA/TIA 258B colour coding shown). Also refer to the notes following the table for additional
wiring guide information.

Figure 2-3. Standard RJ45 Wiring Colour Codes
Note the following cabling information for this wiring guide:
•Only two pairs of wires are used in the 8-pin RJ 45 connector to carry Ethernet signals.
•Even though pins 4, 5, 7 and 8 are not used, it is mandatory that they be present in the cable.
•10BaseT and 100BaseT use the same pins, a crossover cable made for one will also work with the
other.
•Pairs may be solid colours and not have a stripe.
•Category 5 cable must use Category 5 rated connectors.

1200T Series Analog Clock Displays Manual
Revision 1.2 1200T - 5
The maximum cable run between the 1200 and the supporting hub is 300 ft (90 m). The maximum
combined cable run between any two end points (i.e. 1200 and PC/laptop via network hub) is 675 feet
(205 m).
Devices on the Ethernet network continually monitor the receive data path for activity as a means of
checking that the link is working correctly. When the network is idle, the devices also send a link test
signal to one another to verify link integrity. The 1200T rear panel is fitted with two LEDs to monitor the
Ethernet connection.
10/100 This Amber LED is ON when a 100Base-TX link is last detected. The LED is OFF when a
10Base-T link is last detected (the LINK LED is ON). Upon power-up the LED is OFF as
the last detected rate is not known and therefore defaults to the 10Base-T state until rate
detection is completed.
LN/ACT This dual purpose Green LED indicates that the 1200 has established a valid link to its hub,
and whether the 1200T is sending or receiving data. This LED will be ON when the 1200T
has established a good link to its supporting hub. This gives you a good indication that the
segment is wired correctly. The LED will BLINK when the 1200T is sending or receiving
data. The LED will be OFF if there is no valid connection.
2.3. RS-232 COMMUNICATIONS PORT
The COM connector is a female 9 pin D connector used for connecting a computer to control the 1200T
series clocks. This port is wired at the factory as an RS232 DCE port as shown in Table 2-1 and can be
connected directly to most PC COM ports using a ‘straight through’ cable. The RS-232 communication is
57600 baud, 8 bits, no parity, 2 stop bits, no flow control. See section 7 for information on controlling the
clock using the serial port.

2.4. POWER
The 1200T series clocks come with an auto-ranging DC voltage adapter that automatically
senses the input voltage. This power adapter should be used when the clock is operating in
Master mode. Power should be applied by connecting a 3-wire grounding type power supply
cord to the power entry module on the DC voltage adapter. The power cord should be
minimum 18 AWG wire size; type SST marked VW-1, maximum 2.5 m in length. The DC
cable of the voltage adapter should be connected to the DC power jack on the rear panel.
Alternativly, they can be powered from the Ethernet port if the Ethernet supports “Power Over
Ethernet”, type 1. If it is powered from Ethernet, then no power needs to be applied to the
power adapter.
The 1200T Series clocks are not compatible with the power over LTC feature of
the 1200 Series analog clocks. As such they can not be powered from an
upstream 1200 Series clock, neither can they power downstream 1200 Series
clocks. The LTC inputs of the 1200T Series clocks will not be damaged if they are
connected to powered LTC outputs from a 1200 Series clock.
2.5. MOUNTING
The 1200T series clocks are designed to be surface mounted on a wall using two screws in the keyhole
slots provided. The rear panel drawing shown in Figure 2-4 shows the location of the keyhole slots for the
1212T and 1216T clocks.
