of these jumpers, and a detailed illustration of their locations and pin-numbering, are to be
found in chapter 3 of this manual.
The remaining components on this simple low-cost industrial base board are in CMOS SMD
logic and GALs to ensure reduced power consumption/thermal generation over it's predeces-
sor.
1.7 Advantages and Features of the VMOD-2 PepCard
The VMOD-2 is an improved version of the original VMOD, which was designed with a major
objective in mind: to provide a low cost and easy to implement user configurable I/O interface
for industrial interface applications and/or space-savings in many different customer applica-
tions.
This result is a maximized choice of design flexibility. The VMOD-2 provides a very cost-
effective solution, with quick and easy implementation, and full compatibility with the extensive
range of existing VMOD-piggybacks and the ability to accept the planed "enhanced" piggy-
backs of the second generation.
With the flexibility offered by the VMOD-2 and the existing range of industrial I/O modules, you
are able to configure many complex and usually very intense interfaces, in a very quick and
compact way. This may be especially important when needing to add interfaces to an already
existing system, or where when using other products several additional slots or a larger rack/
sub-frames or additional power supplies/cooling, were needed/used with their financial over-
head.
Now with the VMOD-2 you may replace several of these existing cards, or external interface
boxes, with a single VMOD-2, fitted with two piggybacks containing the desired interfaces,
and also offering the added feature of a local reset input.
1.7.1 Features of the VMOD-2 Module
Features of the VMOD-2 are:
* Widest possible range of base address selection to allow up to thirty-two VMOD-2's to
be used in any one system. (Previously only eight original VMOD's could be fitted due to
their fixed base addresses).
* Each piggyback location now supports 11 address lines. (A1...A11 to each piggyback).
* Each piggyback location now has 8/16-bit Databus lines. (D0..D15 to each piggyback).
* Galvanic Isolation between each interface and to the VMOD-2's VMEbus circuitry
depending upon the piggybacks fitted.
* External Reset facility, can be used to cause "local-reset" of the VMOD-2's piggybacks.
* Two Individually configurable piggyback locations, with board ID byte for remote (soft-
ware) configuration identity checking.
* Compact size, VMOD-2 plus two piggybacks containing your chosen interface circuitry,
are all contained within standard single-height, single-slot PepCard dimensions. Choice
of interface connector options, so where needed the connection method can be kept
internal, i.e. via a 50-pin on-board connector.
* Easy maintenance (i.e. swap-and-test, reduce service down-time)
