RELIANCE 802220-14VC Industrial module

The serial ports on the MVME172LX are connected to four 8-pin RJ-45 female connectors (J17) on the front panel. The two IPs connect to the MVME172LX by two pairs of 50-pin connectors. Two 50-pin connectors behind the front panel are for external connections to IP signals. The memory mezzanine board is plugged into two 100-pin connectors. The Ethernet LAN connector (J9) is a 15-pin socket connector mounted on the front panel. The SCSI connector (J23), is a 68-pin socket connector mounted on the front panel.The tables in this chapter furnish pin assignments only. For detailed descriptions of the interconnect signals, consult the support information for the MVME172LX (available through your Motorola sales office).

Remote Reset Connector - J2

 The MVME172LX has a 20-pin connector (J2) mounted behind the front panel. When the MVME172LX board is enclosed in a chassis and the front panel is not visible, this connector enables you to extend the reset, abort and LED functions to the control panel of the system, where they remain accessible.Up to two IndustryPack (IP) modules may be installed on the MVME172LX. For each IP module, there are two 50-pin plug connectors on the board: J5/6 for module A, J7/8 for module B. For external cabling to the IP modules, two 50-pin IDC connectors (J4 for module A, J3 for module B) are provided behind the MVME172LX front panel. The pin assignments are the same for both types of connector.

Ethernet Connector - J9 

The MVME172LX’s Ethernet interface is implemented with a DB15 connector located on the front panel of the board. The pin assignments for this connector are listed in the following table.A four-segment RJ45 connector located on the front panel of the MVME172 provides the interface to the four asynchronous serial ports. The pin assignments for each segment in the connector are as follows.Connector J22 is a standard double-row 100-pin socket connector mounted on the MVME172LX Embedded Controller PWB. It connects to a corresponding 100-pin plug connector on the ECC DRAM mezzanine board and (together with J15) carries the DRAM address, data, and control signals to and from the mezzanine board. The following table lists the pin assignments for J22.
