1C31205G01卡件,EMERSON使用教程
標頭J2和J3用于配置串行端口3和串行端口4，分別與SIM卡選擇配合使用。跳線(xiàn)就位時(shí)1-2，端口配置為DTE。當跨接線(xiàn)處于位置2-3時(shí)端口配置為DCE。端口的跳線(xiàn)設置應匹配相應SIM卡模塊的配置。安裝SIM卡模塊時(shí)，請注意，報頭上鍵入了方向正確。

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.P2 Adapter Preparation (Three-Row)
The P2 adapter for the MVME761 transition module routes the
synchronous and asynchronous serial, parallel, and Ethernet signals to the
MVME761. The P2 adapter also has a 50-pin female connector (J2) that
carries 8-bit SCSI signals from the MVME2603/2604. To run SCSI
devices, you may install an additional transition module that is equipped
with a SCSI port, such as the MVME712B.
Preparation of the P2 adapter for the MVME761 consists of installing a
jumper on header J1 to enable the SCSI terminating resistors if necessary.
Figure 1-16 illustrates the location of the jumper header, resistors, fuse,
and connectors.For further information on the preparation of the transition module and the
P2 adapter, refer to the user’s manual for the MVME761 (listed in
Appendix D, Related Documentation) as necessary.P2 Adapter Preparation (Five-Row)
The MVME761 transition module uses a five-row P2 adapter to transfer
the synchronous and asynchronous serial, parallel, and Ethernet signals to
and from the MVME2600 series VME module. The P2 adapter has a
68-pin female connector (J1) that carries 16-bit SCSI signals from the
MVME2600. (To run SCSI devices, you may install an optional front
panel extension, MVME761EXT, next to the MVME761. The panel
extension supplies both 8- and 16-bit SCSI.) The P2 adapter for the
MVME761 also supports PMC I/O via connectors J3 and J4.
Preparation of the P2 adapter for the MVME761 consists of installing a
jumper on header J5 to enable the SCSI terminating resistors if necessary.
Figure 1-17 illustrates the location of the jumper header and connectors.
