4.2.2 CONNECTION TO A “DCE” DEVICE
Since the Model 1030 is wired as a DCE, you cannot connect it
directly to another DCE such as a modem, multiplexer or printer. If you
need to connect the Model 1030 to another DCE device, you must use
a
null modem cable
wired according to diagram below. We recommend
that you use the shortest possible cable, preferably 6 feet or less.

Note: When connecting to another DCE device, the Model 1030
should be configured for “external clock” (see Section 3.2).
4.3 OPERATING THE MODEL 1030
Once the Model 1030 is properly configured and installed, it should
operate transparently—as if it were a standard cable connection.
Operating power is derived from the RS-232 data and control signals;
there is no “ON/OFF” switch. All data signals from the RS-232 interface
are passed straight through. In addition, one hardware control signal is
passed in either direction.
