2.5 Making Cable Connections
You must connect the station module to the host computer and to line power.
According to your specific application, you also may need to connect the EM to your
target system, or to connect the logic clip cable assemblies.
2.5.1 Host Computer Connection
Connect the 9-lead serial cable between the MMDS 9-pin serial connector and the
COM1 serial port connector of the host computer.
• COM1 is the default serial port. You may use a different host serial port, provided
that you use the appropriate software startup command to specify the port number.
• A 9-to-25-pin adapter came with your MMDS. If the host serial port is a 25-pin
connector, use this adapter between the port connector and the serial cable.
2.5.2 Bus State Analyzer Connection
If your work session includes bus state analysis, you may need the logic clip cable
assemblies. The two logic clip connectors, pod A and pod B, let the analyzer capture
external events. Logic clip connections also let you input external clock signals for the
emulator and analyzer.
The pod A and pod B connectors are on the right side of the station module. Pod A is
nearest the station module power supply. These pod connectors correspond to the
cable A and cable B selections available in the bus state analyzer configuration
window. The Connector Information section includes pinout information for both
logic clip connectors.
If you need only one logic cable assembly, connect it to either pod A or pod B. Orient
the cable connector so that its pin 1 connects to pin 1 of the pod, according to the
keyed plastic. Connect the other end of the logic cable assembly to an external target
point. Optionally, connect the probe tips to the ball clips that come with the cable
assembly, then connect the ball clips to appropriate external test points.
NOTE
Always connect the black (ground) probe tip to an appropriate target-
system ground point before connecting other clips to target points.
The pod A white probe is the external clock input for the emulator;
the pod B white probe of pod B is the external clock input for the
analyzer.
