Hi David, We recently encountered this, testing a server in Taiwan for BSMI approvals. We argued that the display is auxiliary equipment, only used to install and debug, and the port would be not populated in final use. They insist not only on scrolling Hs, but testing all screen resolutions to find worst case.

While testing a network switch to EN 55022/24 and FCC Subpart B, the customer insisted that a scrolling "H" must appear on a visual display used as a peripheral of the network switch. Test setup included a number of PCs, mouse, keyboard, and visual display. All of these were auxiliary/peripherals of the EUT (network switch). According to my understanding of both EN 55022 and ANSI 63.4, scrolling "H" is only relevant if the visual display is the EUT. I consulted a few people in the field and they and us were of the same opinion that scrolling "H" is not relevant if the visual display is peripheral/auxiliary equipment. Any additional opinions are welcome. Thanks in advance for any responses.
