2. Introduction
Functions
SMS7000
If you are using an SMS7000 router control system, you will require an SMS7000 mezzanine card
installed on all router control cards.
Functions
The NV5256 router can be configured with partitions of 4 types. Each partition is considered a
physical level. The physical levels can be of 4 “signal types.” The signal types accommodate the
different characteristics of Miranda’s NVISION series routers and third-party routers.
Any of the router’s ports can be specified as one of 7 different types, generally configuring the port
as a controlling port, a controlled port, or a port whose type can be changed dynamically.
The port types accommodate (1) the different devices you might have in use and (2) the connection
requirements that differ between RS-422 and RS-232 ports.
The signal types and port types are specifiable as parameters in UniConfig. Those parameters, how-
ever, affect the behavior and operating characteristics of the router, which are discussed briefly
here.
on page 27 for more information.
Signal Types
Four “signal types” are available:
NV5256 physical levels in NV9000 router control systems always are “machine control forward.”
Third-party control systems are “machine control reverse.”
A controlling device sends commands to a controlled device. The controlled device passes
responses (such as status) back to the controlling device. A source device can be a controlling
device or a controlled device. A destination device can be a controlling device or a controlled
device.
When you are configuring some NV9000 control panels, you can create a “source is master” button
that toggles whether the source or the destination is the master (i.e., controlling device).
Some control panels have a broadcast button that allows one source to control multiple destination
devices. (“Source is master” is a requirement for machine control broadcast.)
Machine Control Forward
“Machine control forward” means that the source device is the controlling device.
Machine Control Reverse
“Machine control reverse” means that the destination device is the controlling device.
