The HN-510 is wired as a DCE device and as such can be connected to DTE devices such
as PCs with a straight-through cable. When connecting a HN-510 to a DTE device, a
“null modem” cable is required. To effect a null modem cable, cross-wire TXD and
RXD and connect ground. The HN-510 can operate with just these three wires
connected. However, as the WIT2492 does not support software flow control, there will
be no flow control in this mode. If the DTE device fails to respond, connect DCD from
the HN-510 to the DTR and RTS inputs to activate the DCE device whenever the
WIT2492 asserts carrier.

When connecting to the WIT2492M/S4, make sure that all of the inputs (TXD, CFG,
RTS and SLEEP) are terminated for proper operation.
