Motorola MVME162 manual System Controller Select Header J1, Installation of New SIM

Hardware Preparation

Installation of New SIM

1.Observe the orientation of the connector keys on SIM connector J1 and MVME162 connector J10. Turn the SIM so that the keys line up and place it gently on connector J10, aligning the mounting holes at the SIM corners with the matching standoffs on the MVME162.

2.Gently press the top of the SIM to seat it on the connector. If the SIM does not seat with gentle pressure, recheck the orientation. If the SIM connector is oriented incorrectly, the mounting holes will not line up with the standoffs.

Caution

Do not attempt to force the SIM on if it is oriented incor- rectly.

3.Place the two 4-40 x 3/16” Phillips-head screws that you previously removed (or that were supplied with the new SIM) into the two opposite- corner mounting holes. Screw them into the standoffs but do not overtighten them.

The signal relationships and signal connections in the various serial configurations available for ports A and B are illustrated in Figures 2-3 and 2-4.

System Controller Select Header (J1)

The MVME162 is factory-configured as a VMEbus system controller (i.e., a jumper is installed across pins 1 and 2 of header J1). Remove the J1 jumper if the MVME162 is not to be the system controller. Note that when the MVME162 is functioning as system controller, the SCON LED is turned on.

Note

For MVME162s without the optional VMEbus interface (i.e., no VMEchip2), the jumper may be installed or removed without affecting normal operation.
