1st BYTE:

Bit 7 – Defined as 0.

 

 

 

 

 

 

D – “DESTINATION”:

 

 

 

 

 

 

0 - for sending information to the switchers (from the PC);

 

 

 

1 - for sending to the PC (from the switcher). N5…N0 – “INSTRUCTION”

The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is performed via the machine’s keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The instruction codes are defined according to the table below (INSTRUCTION NO. is the value to be set for N5…N0).

2nd BYTE: Bit 7 – Defined as 1. I6…I0 – “INPUT”.

When switching (i.e. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched. Similarly, if switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was switched. For other operations, these bits are defined according to the table.

3rd BYTE: Bit 7 – Defined as 1.

O6…O0 – “OUTPUT”.

When switching (i.e. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be

switched. Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT

NUMBER which was switched. For other operations, these bits are defined according to the table.

4th BYTE: Bit 7

– Defined as 1.

Bit 5

– Don’t care.

OVR – Machine number override.

M4…M0 – MACHINE NUMBER.

Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine numbers will accept (implement) the command, and the addressed machine will reply. For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1.

i

All the values in the table below are decimal, unless otherwise stated

This capability is powered by its compatibility with the latest HDMI 2.0 and HDCP 2.2 standards, making it suitable for high-definition and ultra-high-definition content.

The VS-88DTP supports a variety of signal formats including HDMI, DTP (Digital Twisted Pair), and analog audio. The DTP technology utilizes twisted pair cabling, allowing for the transmission of video signals up to 70 meters at 4K resolution or up to 100 meters at lower resolutions. This flexibility ensures that integrators and installers can maintain clean and efficient cable management, reducing clutter while providing sufficient distance coverage.

One of the key technological advancements incorporated in the VS-88DTP is its built-in scaling and switching capabilities. This allows users to seamlessly switch between different input sources without interrupting the signal flow. The device features a user-friendly interface that can be operated through various control methods, including a front panel, an IR remote, or through a network using its built-in web interface or third-party control systems.

For audio management, the VS-88DTP includes stereo audio inputs and outputs, allowing for integration with audio systems easily. Additionally, it supports audio routing, which is crucial for environments requiring separate audio and video signal handling.

Reliability is another defining characteristic of the Kramer Electronics VS-88DTP. With its robust hardware design and built-in redundancy features, users can be assured of continuous operation even in demanding scenarios. Furthermore, the device is compatible with Kramer's extensive line of products, making it a scalable solution ideal for growing systems.

In conclusion, the Kramer Electronics VS-88DTP equips users with high-performance switching and scaling capabilities for both video and audio. Its range of features, advanced technologies, and comprehensive compatibility make it an excellent choice for professionals seeking reliable and high-quality signal distribution solutions in various media-rich environments.
