4 Signals
This chapter explains the signals and their statuses used in the tally light system using this product.
Tally control signals
A tally control signal is a physical or logical signal output from a video switcher for the purpose of controlling a tally lamp. The Base Unit of this product operates by receiving the tally control signal.
Input numbers
The tally control signal outputs a signal which indicates the selection status of multiple video channels that can be input to the video switcher. In this device, to distinguish between these channels, a unique “input number” is assigned to each channel, and these are referenced by the input number.
When using dry contacts inputs, the input numbers are assigned the same as the point numbers, 1 to 16. However, when operating with three input states, “Not selected”, “Preview” and “Program”, the input numbers are assigned 1 to 8. When using other interfaces, the input numbers usually correspond to the video input numbers of the video switcher, but this may not be the case when using a software switcher, etc.
Input status
The tally control signal can have three states - “Not Selected,” “Preview,” or “Program” - independently for each channel.
Tally control signal physical interface
The physical interface that the video switcher uses to output the tally control signal varies depending on the video switcher model. The interfaces listed in the table below can be connected to the Base Unit of this product.
Please check the following that the models listed in the table below may be updated in the future. For the latest information, please check the compatible switcher list on the product page.

Dry contacts signal interface
For dry contacts signal signals, use a dedicated cable to connect to the tally input connector on the Base Unit. If the input status is operated in only two states, “Not selected” and “Program”, 16 channels can be input. If the input status is operated in three states, “Not selected”, “Preview” and “Program”, two points are used per channel, allowing eight channels to be input.
Connector
The type of connector on the Base Unit is a D-SUB 25-pin female. The compatible connector is a D-SUB 25-pin male.
Signal assignment
Signal assignment is as shown in the table below.
If the input mode is set to 16 channels of program only, input numbers 1 to 16 are assigned one contact each, and when a contact is made, the corresponding input number is recognized as being in the program state. If the input mode is set to 8 channels of program/preview, input numbers 1 to 8 are assigned two contacts each, and depending on which contact is made, the corresponding input number is recognized as being in the program or preview state.

Equivalent circuit diagram
The equivalent circuit diagram for non-voltage contact signal input is shown below.
Ethernet interface
In the case of Ethernet, the Ethernet interfaces of the video switcher and the Base Unit are connected to the same network and communicate via IPv4.There is no limit to the number of logical channels that can be input, and the value output by the video switcher is used as the input number.
USB interface
In the case of USB, a USB cable is used to physically connect the video switcher and the Base Unit. There is no limit to the number of logical channels that can be input, and the value output by the video switcher is used as the input number.
Lamp ID
The lamp ID is a number used by the Base Unit to distinguish between lamps connected to the system, and can range from 1 to 128. Lamp behavior can be defined for each lamp ID.
A Lamp Unit always has one lamp ID as a setting value for which lamp ID it will behave. The lamp ID of a Lamp Unit can be set using the DIP switch on the rear side of the Lamp Unit.
It is also possible to have multiple Lamp Units with the same lamp ID set in one system. In this case, these Lamp Units will behave in the same way in parallel. There is no limit to the number of Lamp Units with the same lamp ID that can be connected.
Restrictions on lamp IDs of Lamp Units connected wirelessly
When using the wireless connection function between Lamp Units, there are restrictions on the lamp IDs that can be used. Only 16 lamp IDs selected from the following range (can be set on the Base Unit) and can be transmitted wirelessly.
1 ~ 16
17 ~ 32
33 ~ 48
49 ~ 64
65 ~ 80
81 ~ 96
97 ~ 112
113 ~ 128
Therefore, the lamp ID set for the Lamp Unit that will be used as a wireless client must be a value within the selected range.
If you use both wireless and wired connections at the same time, this restriction does not apply to Lamp Units connected via wired. For example, if the range of lamp IDs for wireless transmission is set to 1 to 16, the lamp IDs 1 and 16 can operate as wireless client devices, but the lamp ID 17 cannot. However, if you connect a Lamp Unit via Ethernet, lamp ID 17 can also be used.
Mapping
Mapping is information that defines how a lamp ID changes when a certain input number changes to a certain input state. Mapping allows you to determine the behavior of a certain lamp ID for a certain input number.
Default mapping
The following mapping is set as the default value when this product is shipped from the factory. The default mapping is the same regardless of the physical interface of the tally control signal.

Even if the power supply complies with USB Power Delivery and can supply more than 10 watts, it cannot be used if it cannot output 2.0 amps at 5 volts. Please check the instruction manual and nameplate of the power supply before use.
The Base Unit has two power input terminals, MAIN and SUB. When using a single power supply, connect the power supply unit specified in this manual to MAIN. When using dual power supply, connect both MAIN and SUB to the power supply unit. When connecting the Base Unit to a power supply unit, be sure to use a cable with a current resistance of 2.0 amps or more and USB Type-C connectors on both ends.
When using dual power supply, also refer to the section on power supply redundancy.
→ Power supply redundancy
Power supply redundancy
By connecting different power supplies to the MAIN and SUB power input terminals at the same time, the power supply to the Base Unit can be made redundant. When both systems are receiving power, the Base Unit will give priority to receiving power from the MAIN side, and if the power supply from the MAIN side is interrupted, it will switch to receiving power from the SUB side and continue operating. Also, if power is supplied to the MAIN side while receiving power from the SUB side, the power receiving will be switched from SUB to MAIN and operation will continue.
Power switching is performed without interruption, and hot swapping of power supplies is also possible. However, depending on the power receiving status of the Base Unit and the power supply capacity, a power interruption may occur during switching. Please perform sufficient verification when operating power redundancy and hot swapping.
Tip
Depending on the model, a power bank may be equipped with an auto power off function that automatically turns off the power if the battery is left unloaded for a certain period of time.

Troubleshooting
I can not connect the Base Unit and my switcher.
Connecting via GPIO cable
Please check and make sure that the video switcher connection interface is set to “GPIO”.
→ Changing the connection interface with the video switcher
Additionally, check and confirm that the GPIO cable used for connection complies with the specifications of the Base Unit and video switcher.
Also, if you are using a switcher that allows users to freely set the GPIO output signal information, please check the settings again.
Connecting via USB
Please check and make sure that the video switcher connection interface is set to “USB”.
→ Changing the connection interface with the video switcher
Try replacing the USB cable used for connection with another one (preferably a new one) and check again whether it is connected properly.
We also recommend checking whether the connected video switcher is a model that supports USB connection with this product. Even if the video switcher is equipped with a USB connector, it may not be compatible with USB connection with this product.
→ Compatible switcher list
Connecting via Ethernet
Depending on the network environment and devices are connected, problems may occur with the connection of each device. In such cases, you may be able to connect successfully by turning off DHCP in the network settings of the connected Base Unit and the switcher, and manually setting a static IP address (fixed IP address).
→ How to set a static IP address (fixed IP address)
Issues Regarding Connectivity with TriCaster
If the TriCaster does not connect to the Base Unit, please check that the TriCaster password has been unlocked.
