The I/O tab is used to configure the options for each of the individual hardware ports. 

The I/O ports 

The I/O ports in this list will be automatically generated based on the order code of the connected clock. 

For each point on the list, the point will demonstrate the type of I/O the port is equipped with, what port number that has been assigned, A description of the type of port that is available, and lastly the draw from each port (if appropriate) 

Outputs

User-Defined Pulse

If the user has chosen the "User-defined pulse" option they are given the opportunity to configure a custom pulse that can output every, second, minute, hour or day. This is done by configuring the "every" field. The user can then configure how many pulses occur for each period under the "pulses" field. 

The offset and duration of the pulses can also be configured and are measured in hundredths of a second. 

DCF-77 Simulation 

The DCF77 stimulation signal can be modified so that the user can invert the polarity of the pulse output. Unfortunately, this is the only configurable option available for DCF-77. 

IRIG-B

In the IRIG-B pulse options, the user has the ability to choose from either DCLS (DC level shift) or Modified Manchester. When the DCLS output is selected the port will output a IRIG-B00x signal, whereas when the Modified Manchester signal is select an IRIG-B22x signal will be outputted.

Much like the user-defined and DCF-77 pulse types, the user can also choose to invert the polarity of the pulse. 

Serial Strings

There are four configurable options for the Serial String output. The first is the serial string type, which defines the time string format when using the serial port. The table below can be used to decode the different strings.

The time source, field will allow the user to configure which output time source they would like to use, the two options will be Local time and UTC  time.

The parity of the signal can be configured to dictate whether there should be a even, odd or no parity. 

Lastly, the Baud rate can also be configured to be either 1200, 2400, 4800, 9600, 19200, 38400 Baud.

AM IRIG-B

The AM IRIG-B output has very few configurable options, instead display some information about the AM IRIG-B output.

T1/E1 & Frequency outputs   

Initial frequency outputs can be configured to output a base frequency of 1.544MHz (T1/J1) or 2.048MHz (E1) as well as a none base frequency of 10MHz

Framed frequency outputs, however, provide a lot more configurable options, allowing the user to be able to configure, the framing format, the encoding method, waveform shape, the transmitter impedance, fill pattern and decided whether it is a high impedance output, long haul or SSM.

Each of the options will depend on whether the output is being used as T1, J1 or E1. The table below will allow a quick view of each available output options for each of these. 

Inputs

IRIG-B Monitor

This function is used when the IRIG-B input is being monitored, to determine if the IRIG-B port fails in which case an alarm will be raised. 

IRIG-B 

If the clock is synchronised to a timing source other than IRIG-B and the IRIG-B input port fails, no alarm is raised. However, if this port is being used to synchronise the clock, and all timing sources (including IRIG-B) fail, an alarm may be raised dependent on the sync settings.  

Event Record 

The event record type allows the clock to record time tags in accordance with the rising edge of an incoming pulse. 

Alarms

The Tekron configuration software will list the alarm ports fitted to the connected clock. When an alarm port is selected an information box under the I/O ports section on the I/O tab will appear and give an overview of its functionality.

Some clocks such as the obsoleted products TSC100 and NTS 100 allow the user to configure the alarm relay output. When selected, the information box will show a list of alarm conditions and their current state.
