When you are connected, proceed to Paragraph
and make a test call.
2-9. RED SERIAL DATA PORT 1
The
RED SERIAL DATA PORT 1
is available on the rear panel of all STEs (
The
RED SERIAL DATA PORT
or
RED SERIAL DATA PORT 1
, is a DB-25 connector. This data port is
located at the rear of the STE, to support your synchronous and asynchronous data communications.
The port can be configured for EIA-530A or EIA-232 operations via selections in the STE HMI menus. At
this port, the STE functions as a Data Communication Equipment (DCE). Refer to
appropriate pin outs. Use this table to identify which pin on the connector receives which specific logic
functions or signals.

* The timing (clock) for the transmit element is supplied by the DCE (the
STE) via pins 12 and 15 for an EIA-530A interface or just pin 15 for an EIA-
232 interface.
Use a shielded serial cable to connect a PC or FAX unit to the
RED SERIAL DATA PORT
on the rear of
the STE unit. All connections to this port must be made with TEMPEST approved, full-foil and 85 percent
braid covered cables.
Although not part of the initial installation, you should be aware there is a “STE Toolset Program” that
runs on a PC connected to the STE’s
RED SERIAL DATA PORT
. Refer to
for more
information on the STE Toolset.
2-10. RED SERIAL DATA PORT 2
The RED SERIAL DATA PORT 2 is available on the rear panel of the DATA STE, STE-R (but not active),
STE-RI, and STE-RT.
Pin 25 is connected to a hard-reset line. When it may become necessary to invoke a STE hard-reset, you
can momentarily short Pin 25 to Pins 1, 7 or 23.
2-11. INITIAL OPERATIONAL CALL
After Network Settings have been completed, the STE should be tested on all connected services. This
ensures that the STE and all services can perform at the minimal level – non-secure (NONSEC) voice.
You do not need a FORTEZZA PLUS
KRYPTON™
ENHANCED CRYPTOCARD CARD to make test calls.
At this point, your STE is at the default settings, except for the network setting you have completed to this
point. Therefore, the displays for the non-secure calls will be based on the “Auto-secure” Initial Secure
Mode formats for your service being tested.
