2.3.2 Interface Port
The T-96H signals are defined as DCE.
Connection to user DTE is made via a DE-
15 female connector. This connection meets
the
DATARADIO
Interoperability Standard
(DIOS).
Users can build a suitable cable by referring
to the connector pinout and the Interface
Signal Description given in the next section.
A cable for connection to a PC AT type
DE-9 connector is available from
DATARADIO
as p/n 730 03267-001.
Important Note:
The T96H RSS kit, used
to configure the T-96H, includes a special
setup cable, p/n 730 03266-001.
Do not use
this cable to connect a user application.
Doing so will result in the T-96H switching
to “setup mode”, in which case it will not
transmit or receive user data. The green
LED flashes to indicate that the unit is in
this mode.
