210 Trinix NXT — Installation and Service Manual
Section 3 — Hardware Installation
In systems controlled by SR-33000 boards, Monitor Expansion jumpers JN3
and JN4 on the SR-33000 boards must be set to “Exp.”
Note Output monitoring is not available for input-expanded systems controlled by
an SR-33000 Sync/OPM board.
Trinix Asymmetrical Frames
In expanded systems, output monitors are cascaded from expanded frames
to the main frame via the TRX-SR for the 256x512 and the TRX-OPM for the
128x256, and 512x1024 output monitor inputs. See
Figure 115 on page 202
for Monitoring connection locations.
Expansion of two 128x256 Asymmetrical frames to form a 256x256 with
output monitoring. There will be missing ports in the inputs that will need
to be adjusted in the Control system.
