VMOD-2/VMOD-2D Product Overview 1. Introduction 1.1 Product Overview VMOD-2 is a "User Configurable" Industrial I/O module with the ability to fit any two (identical or different) standard sized VMOD piggybacks. Each fitted piggyback shares half of the front panel's 50-way connector allowing a flat-ribbon cable to be easily routed to either one or two end devices.
VMOD-2/VMOD-2D Product Overview please use a VMOD-2 with a board index of 01 upwards since this will have an increased galvanic isolation gap around the 50-way external interface and 26-way piggyback I/O pin areas. 1.3 Glossary of Terms This is a brief description of some of the abbreviations used throughout this manual.

VMOD-2/VMOD-2D Functional Description 2. Functional Description The VMOD-2 is a very simple and compact Modular Base-board accepting any two VMODPiggyback sub-modules for user-configurable I/O in any VMEbus system. It is better suited for use in conjunction with other VMOD-2's in a VMEbus system than the original VMOD, which only had eight different base addresses. This chapter will describe the "physical" interfaces of the VMOD-2, and the function of the external "local" reset interfaces.

VMOD-2/VMOD-2D Functional Description The External Reset is limited to the VMOD-2 and it's piggybacks, and will not reset the VMEbus unless your application software demands it to. I.e. via the polling of an output register to detect a "reset" state. Special note! There can be occasions when spurious interrupts are caused with the use of the "local" reset facility. This can happen when a VMOD-2 IRQ is cleared by the local reset before the VMEbus system has had a chance to clear the interrupt itself.

VMOD-2/VMOD-2D Functional Description Caution! When using the VMOD/VMOD-2 with any piggyback, take care to note that the terms ST1 and ST 2 used in the piggybacks user's manual and circuit diagrams, refer to the connectors of the Piggyback and equate to their Plug 1 and Plug 2 (ST from the German word "Stecker") these fit to BU1a and BU2a or BU1b and BU2b (BU = "Buchse" = Socket) on the VMOD/VMOD-2.
VMOD-2/VMOD-2D Functional Description to help see which pins are only on the VMOD-2, we have shown these additional lines in bold/italics.
VMOD-2/VMOD-2D Functional Description Remember! If any of the piggybacks you wish to use need any of the signals shown bold/italic above (i.e. a 5230-xx type), a VMOD-2 set for an 8 KByte wide address area must be used. Any piggyback not needing these additional lines can be used on the VMOD-2 in either a 256 Byte or 8 KByte address width setting. 2.5.
VMOD-2/VMOD-2D Functional Description Caution! The term "ST2" on the schematics at the back of any piggyback manuals, refer only to the ST-2 connector of the actual piggyback (which plugs into the above BU2) not to the VMOD-2's ST2. Take care not to confuse these when making connections to your VMOD-2 front panel. Remember also that the pin-outs change when swapping the previously fitted piggybacks around or replacing them with different types.

After fitting, please look under the fitted piggyback to ensure that every pin of it's front 26-pin connector is in a socket hole. If any holes are not occupied or any pins are left without a hole, there is a strong possibility that the piggyback is the wrong-way round and/or displaced in pin number/height.

VMOD-2/VMOD-2D Installation 4. Installation This section describes how to install the VMOD-2 fitted with one or two piggybacks for use in your VMEbus system. Before you proceed with this section please make sure that you have configured all of the necessary VMOD-2 jumpers as described in the preceding section. 4.1 VMEbus Connection Caution! Before installing or removing any VMEbus boards always turn off the power to the bus and any external peripherals.
VMOD-2/VMOD-2D Installation 3/. Check the desired external interface leads, lengths and connector orientations suit your intended application and match the connector types required for your targeted external devices. 4/. Ensure all power is off, including that to all other devices connected to the VMEbus system. 5/. Choose the desired slot for your VMOD-2 with it's chosen piggyback(s) , and if necessary reposition the other modules. For this chosen slot you must remove the IACK* daisy chain jumper.

VMOD-2/VMOD-2D Installation The recommended maximum cable length should be limited to 5 meters (~15 feet) to ensure minimum voltage drop/risk of cables becoming damaged/trapped, etc Caution! Ensure that the current ratings of the connected flat-band cables are never exceeded. 4.5 Front Panel Functions The front panel of the VMOD-2 has only the 50-pin connector on it. The odd numbered pins of this connector are on the right side when looking at the connector from the VMOD-2's front (see figure 4.5 below).
