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 WIT2410 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
WIT2410 asserts carrier.
When connecting to the WIT2410M/S4, make sure that all of the inputs (TXD, CFG,
RTS and SLEEP) are terminated for proper operation.
9.3. Approved Antennas
The WIT2410M/S4 is designed to ensure that no antenna other than the one fitted shall
be used with the device. The end user must permanently affix the antenna by using an
adhesive on the coupling such as Loctite, or ensure the antenna has a unique coupling.
The table below lists the antennas which can be purchased directly from Murata. Contact
Murata Technical Support with any questions.

Note: The WIT2410M4 is the
standard part number and has
the serial connector pins
pointing down allowing
connection to a mother board
without using a cable.
WIT2410S4 has the serial
connector pins pointing up.
