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 WIT2410T 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 
WIT2410T asserts carrier.   
 
When connecting to the WIT2410TM/S4, make sure that all of the inputs (TXD, CFG, 
RTS and SLEEP) are terminated for proper operation. 
 
 

The WIT2410TM/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.
