Pin Assignment
The ELSA ERAZOR II and ELSA VICTORY Erazor LT issue analog signals in accordance
with the requirements of Guideline RS-170. The synchronization information is sent sep-
arately. If your monitor provides a switch for the input impedance, you should select '75
Ohms' (= '75
Ω
') for the R, G and B video inputs and '2 kOhm' (= '2 k
Ω
') for the sync inputs.
You should only try other switch settings at the sync inputs if your monitor expects sync
levels other than those used by normal monitors and does not produce a stable display.
The switches are labeled “Low” and “High” only on some monitors. You can then refer
to your monitor manual to find out what input impedance level this refers to, or you can
experiment to find a position in which a stable image appears in all graphics modes.
