Emulation mode:
Each port can be configured to emulate a DCE port or a DTE port by setting the appropriate
switches on the MSDL. For details on how to set the switches, refer to
of this document.
DCE is a master or controlling device that is usually the source of information to the DTE and
may provide the clock in a synchronous transmission linking a DCE to a DTE.
DTE is a peripheral or terminal device that can transmit and receive information to and from a
DCE and normally provides a user interface to the system or to a DCE device.
Interface:
Each MSDL port can be configured as an RS-232 or an RS-422 interface by setting the
appropriate switches on the card.
Table 144: RS-232 interface pin assignments
specifications for EIA and CCITT standard circuits. It shows the connector pin number, the
associated signal name, and the supported circuit type. It also indicates whether the signal
originates at the DTE or the DCE device.
This interface uses a 26-pin (SCSI II) female connector for both RS-232 and RS-422
circuits.
