1.0 GENERAL DESCRIPTION The VX402C-64 Active Carrier allows an A- or B-size VME, VXI, or VME64 module to be used in a C-size VXI mainframe chassis. Throughout the rest of this manual, the VME/VXI card being carried will be referred to as the VME module. The carrier provides an actively-buffered electrical interface for the standard VME bus signals. The VX402C-64 does not support the full VME64 extension bus; however, -0001, -0003, and -0004 versions provide +3.3V power to the P1 row

2.0 INSTALLATION 2.1 UNPACKING AND INSPECTION In most cases the VX402C-64 is individually sealed and packaged for shipment. Verify that there has been no damage to the shipping container. If damage exists then the container should be retained as it will provide evidence of carrier caused problems. Such problems should be reported to the carrier immediately as well as to C&H. If there is no damage to the shipping container, carefully remove the module from its box and anti static ba

3.0 FUNCTIONAL DESCRIPTION 3.1 GENERAL VX402C-64 is a general purpose carrier module for VXI C-Size chasses. The module provides actively buffered signals, which meet all VME specifications, to the VME module. A functional block diagram is shown in Figure 5.

3.2 TRIGGERS Both ECL and TTL triggers are supplied through the VX402C-64. There are switches on the carrier which are used to set the direction of the triggers (to the backplane and from the backplane). 3.2.1 TTL TRIGGERS Eight TTL Trigger lines pass through the VX402C-64 to the front panel: TTLTRG0-7. Each trigger line may be set as an input or output trigger. The trigger direction is set using switch S1 which can be seen in Figure 6. The directions are also clearly marked on

3.2.2 ECL TRIGGERS The VX402C-64 supports two ECL Trigger lines: ECLTRG0-1. Each trigger line may be set as an input or output trigger. The trigger direction is set using switch S2 which can be seen in Figure 7. The trigger directions are clearly marked on the board itself.

3.3.3 PASS-THROUGH CONNECTORS One major difference between the VME bus and the VXI bus is that the outer rows of the P2 connector are not defined on the VME bus and they are defined on the VXI bus. For this reason, the VX402C-64 Active Module Carrier provides a Pass-Through Connector system that be used to optionally connect or not connect the VME P2 Rows A & C signals to the VXI P2 Rows A & C signals. The VX402C-64 can be shipped with an optional pass-through connector cable (1102850

A one-to-one cable that connects Pin 1 (C32) on the VXI side to Pin 1 (C32) on the VME side, and so on, could only be used if the VME module was designed to meet all of the VXI bus specifications for these pins. If the installed VME module can not handle -24V, +24V, -5.2V or any other signal on the corresponding pin, then a one-to-one cable can not be used. The signal list for both the VXI side and the VME side is shown in Table II. The pass-through connectors on the PCB are standard 64

3.4 SUMBUS CONFIGURATION The VX402C-64 provides a direct connection of the SUMBUS signal through the pass-through connector to the front connectors. The board also has a prototyping area so that the user can hardwire a custom buffer for the SUMBUS signal. 3.4.1 SUMBUS CUSTOM AREA The SUMBUS custom area consists of a prototyping grid, ±12V supplies, and two jumpers for configuring the signal. The prototyping area is a 10x10 grid of 0.1” spaced through-hole pads which can be used in

3.4.2 SUMBUS JUMPER SETTINGS In order to use the SUMBUS signal, the jumpers J11 and J12 must be configured properly. The three different settings for the jumpers can be seen in Figure 10. The SUMBUS signal can be connected directly to the front panel (A), connected through the prototyping area (B), or disconnected (C). The pass-through connector must be installed for the SUMBUS signal to route to the front panel. Also, both jumpers must be configured the same, or the SUMBUS signal
