(2) The HSD system is capable of being integrated with the MCS--3000, MCS--6000,
MCS--4000, and MCS--7000 multi--channel (MCS) satellite communications
(SATCOM) systems with Aero--H/H+ high gain antennas (HGA). The HSD system is
interfaced with its own dedicated 40 W high power amplifier (HPA).
(3) The L--band radio frequency (RF) outputs of the HSD system HPA and the satellite
data unit (SDU)/radio frequency unit (RFU) 40 W HPA is combined with a high power
combiner. The output of the high power combiner drives a common diplexer/low noise
amplifier (DLNA) and a nominal 12 dB gain antenna. The SDU manages the satellite
selection and steers the HGA.
(4) The Aero--H/H+ SDU and HPA requires no hardware or operational software
modifications, and operates without knowledge of the HSD system presence.
However, each SDU used in conjunction with the HSD system will require advance
configuration of its data logging terminal (DLT) parameter settings.
(5) The SDU’s DLT RS--232 port must be configured to transmit the ASCII data given in
Table 1-1, at a rate of approximately 1 Hz, for the functions in Table 1-1 to be
performed in the HSD system (SDU to HSU transmit only).

(6) The SDU CMT keystrokes given in Table 1-2 (starting from the main menu) are
required to configure the SDU to broadcast the desired data from its DLT port.
