Hardware Preparation and Installation

Headers J2 and J3 are used to configure Serial Port 3 and Serial Port 4,
respectively, in tandem with SIM selection. With the jumper in position
1-2, the port is configured as a DTE. With the jumper in position 2-3, the
port is configured as a DCE. The jumper setting of the port should match
the configuration of the corresponding SIM module.
When installing the SIM modules, note that the headers are keyed for
proper orientation.
For further information on the preparation of the transition module, refer
to the user’s manual for the MVME761 (listed in Appendix D, Related
Documentation) as necessary.
The next three figures illustrate the MVME2603/2604 base board and
MVME761 transition module with the interconnections and jumper
settings for DCE/DTE configuration on each serial port.
