Figure 2-8 shows the connector of the BDR rear panel DATA 2 port (J3). The connector is a
25 pin D-sub. The part number is ITT DBU-25S-FO or equivalent. A mating connector with a
metal backshell for shielding purposes should be used.

2.4 COMPONENT JACK LOCATIONS
The following paragraphs describe the purpose and location of the jacks for each of the radio
assemblies.
2.4.1 MOBILE DATA RADIO JACK LOCATIONS
Figure 2-9 depicts the MDR connector panel. The MDR front panel contains two data jacks
,
DATA 1
(J2) and
DATA 2
(J3). The MDR transmits and receives data from the control
equipment across the
DATA 1
port (J2). A cable connects the
ANTENNA
port (J5) to the
antenna. A cable connects the
DIAGNOSTIC
port (J4) to an LCP terminal providing a menu-
driven user interface (refer to paragraph 2.5.2). Port
POWER IN
(J1) connects the MDR to
the VDC power source.
DATA 2
port is an RS-232 port that can be connected to customer provided equipment as
required.
DATA 2
provides asynchronous data that is sent from the BDR. The parameters of
this port are programmable via the diagnostic terminal. The
DIAGNOSTIC
port is
unconnected during normal operation.
