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 Sig-
nal 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.

T-96H.
CTS. Clear to Send. Asserted when the
T-96H is ready to accept TX Data.
RTS. Request to Send. Causes the T-
96H to transmit when asserted by the
DTE.
DCD. Data Carrier Detect. Asserted by
the T-96H when a data signal is being
received.
DTR. Data Terminal Ready. Asserted by
the T96HRSS/OFLNDIAG to select
