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 sys-
tem.
5/. Choose the desired slot for your VMOD-2 with it's chosen piggyback(s) , and if neces-
sary reposition the other modules. For this chosen slot you must remove the IACK*
daisy chain jumper. (See figure 4.3 on next page).
6/. Place the PCB into the card guides for the desired slot.
7/. Push the module into it's position carefully, checking that the flat ribbon cable (if con-
nected to optional internal 50-way header) does not become snared or damaged. Once
the insertion force of the 96 way VMEbus connector has been overcome, the front panel
securing screws can be tightened up.
8/. To ensure reduced risk of shock hazard when using higher voltage piggybacks, fit cov-
ers to unused slots either side of the slot into which the VMOD-2 with such piggybacks
is to be fitted.
9/. Connect the flat ribbon interface cables to your chosen external devices.
10/. Restore power only when you are satisfied that all the modules are correctly electrically
and mechanically fitted.
Removing the VMOD-2 (or any other PepCard) is virtually the reverse procedure, where it is
especially important to remember when removing any modules like the VMOD-2, with the
option for externally powered devices, etc. to power down each of these external sources and/
or disconnect the external connector, otherwise you may risk short-circuiting the external
devices power supply outputs, with risk of damage to the interface leads, the interface on the
piggyback and even the circuit traces on the VMOD module itself.
