Power interruption
MultiStation is immune to most power interruptions of less than three
seconds. Since the keyboard power is supplied from MultiStation, you may
need to reset it if a power interruption happens.
Video distance capability
The limitation on driving distance is usually due to the quality of the video.
Table 11 shows the distances, resolution and quality of video that can be
expected. The table uses a letter, which shows the cable type, and a number
that refers to the quality of the video, as described below. Rose Electronics
does not recommend systems where the video quality is 1 or 2. There are
further capabilities not listed here in order to send the higher resolution video
longer distances. Please contact Rose Electronics technical support for more
details.
Z – Micro coax cabling
C – Mini coax cabling
4 – Perfect or near perfect; unable to easily detect defects in screen.
3 – Very acceptable; images clear, small reflections around lettering
depending upon color; if you examine the screen closely you will find defects.
2 – Acceptable; slightly fuzzy images; readable text, acceptable for casual
use, but not for prolonged viewing as this will cause eye fatigue.

75Hz refresh rate used for testing.
