1.2 EM LAYOUT
Figure 1-1 shows the layout of the D32EM. Jumper J1 must be set to position C/D. Jumper
headers J2 and J3 let the user select the clock source. Jumper J4 determines the logic
direction of the RESET signal at the target connector. Switch array S1 determines which
device is to be emulated. Switch array S2 must have all switches set to closed.
Connectors P4 and P5 provide the interface to the target system. If you install the D32EM
in the MMDS05 station module, the target cable passes through the slit in the station module
enclosure. Connector P1 connects to a logic analyzer. (Connector P1 has more significance
for an EVS system, as an MMDS05 system includes a bus analyzer.) Expansion header
connectors P2 and P3 connect together the EM and the control board (for an MMDS05) or
the EM and the platform board (for an EVS).
