Both MVME761-0x1 models use the same transition module. The MVME761-001 comes with a P2 adapter that connects to a 3-row DIN chassis backplane. The MVME761-011 comes with a P2 adapter that connects to a 5-row DIN chassis backplane. MVME7616E Transition Module Installation and Use (6806800A43B)
The SIM contains the receiver and transmitter circuits for converting the input and output signals of the host VMEmodule to the appropriate serial data communication protocol. MVME7616E Transition Module Installation and Use (6806800A43B)
EIA-232-D DTE SIM232DTE5E 01-W3877B11A Additional SIMs may be released. Please see your Emerson representative for a complete list of SIMS that are available for the MVME761-0x1. P2 Adapter Boards The P2 adapters route the asynchronous and synchronous port, printer port, and Ethernet signals to the MVME761 transition module.
1. You will need to purchase or fabricate the port cables.

If you supply your own 64-line cable to connect the P2 adapter to the MVME761 transition module, the cable should not be longer than 1.5 feet. A longer cable is likely to cause problems, especially for the Ethernet and parallel port signals. MVME7616E Transition Module Installation and Use (6806800A43B)
Class A equipment. For minimum RF emissions, it is essential that you implement the following conditions: Install shielded cables on all external I/O ports Connect conductive chassis rails to earth ground to provide a path for connecting shields to earth ground Tighten all front panel screws MVME7616E Transition Module Installation and Use (6806800A43B)
Modules (SIMs). Unpacking the Hardware The MVME761 is packed in an antistatic wrapper to protect it from static discharge. Emerson strongly recommends that you use an antistatic wrist strap and a conductive foam pad when handling the equipment. Electronic components can be extremely sensitive to electrostatic discharge (ESD).
Figure 2-3 on page 3. Gently press the top of the SIM to seat it on the transition module SIM connector. If the SIM does not seat with gentle pressure, re-check the alignment of the connectors. MVME7616E Transition Module Installation and Use (6806800A43B)
Do not force the SIM onto the transition module. 4. Secure the SIM to the transition module standoffs with the two Phillips-head screws provided. Do not over tighten the screws. Figure 2-3 Installing the SIM 1911 9609 MVME7616E Transition Module Installation and Use (6806800A43B)

6. Attach the P2 adapter, for either the 3-row or 5-row version, to the backplane connector that is directly in line with the P2 connector on the host VMEmodule. 7. Orient pin 1 of the P2 adapter’s connector with pin 1 of the backplane connector. MVME7616E Transition Module Installation and Use (6806800A43B)

Make sure there is good contact with the transverse mounting rails in order to minimize RF emissions. 11.Install the chassis cover, making sure that cables are not pinched by the cover. 12.Connect the power cable to the AC power source. MVME7616E Transition Module Installation and Use (6806800A43B)
The MVME761 transition module contains a small amount of “house keeping” circuitry. Bulk capacitors are on the power sources (+5Vdc, +12Vdc, and -12Vdc). Pullup resistors put the inputs to the host board in a known high even when no SIM is installed. MVME7616E Transition Module Installation and Use (6806800A43B)
MVME761 transition module multiplex and demultiplex some of the P2 signals. This function, called P2MX is transparent to the software and the user. Four pins are used for the signal multiplexing: MXCLK MXSYNC# MXDO MXDI MVME7616E Transition Module Installation and Use (6806800A43B)
MXSYNC# is clocked out using the falling edge of MXCLK and MDXO is clocked out with the rising edge of the MXCLK. MXDI is sampled at the rising edge of MXCLK (the transition module synchronizes MXDI with MXCLK’s rising edge). MVME7616E Transition Module Installation and Use (6806800A43B)
-12V supply. The diodes are located on the transition module rather than on the SIM due to space limitations. For all port interfaces, the SIMs support the transmitter signal element timing as either input or output signals. MVME7616E Transition Module Installation and Use (6806800A43B)
