3.2 EXPANSION UNIT CONFIGURATION
Details of the standard PGSC Flight Laptop Configurations are provided in Annex 1.
Configuration 1 (PGSC Flight Laptop without Expansion Unit) is listed in this section only to
provide completeness for standard configurations. The PGSC with Expansion Assembly
(Configuration 2, 3, 4, & 5) contains the interfaces listed in section 3.1 plus the combinations of
the following:
Configuration 1
• Stand alone PGSC Flight Laptop without expansion assembly.
Configuration 2
• PCMMU port - The Pulse Code Modulation Master Unit (PCMMU) is the Orbiter central
processing unit that includes all of the Orbiter downlink (OD) telemetry. Select PCMMU
data may be de-commutated by the PGSC PC-DECOM software and routed via packetized
data to other PGSC’s.
Configuration 3
• OCA port - The OCA includes two functionally independent sections: the Ku-band
• interface and the modem interface. The OCA system, consisting of a single printed circuit
board, associated software, and interface cable, provides a means for two-way transfer of
computer files between a ground-based computer and a Payload and General Support
Computer (PGSC) on-board the Orbiter.
Configuration 4
• Proshare (AT-Bus) Card - The Proshare (AT-Bus) Card provides a means for two-way
transfer of video teleconferencing sessions between a ground-based computer and a
Payload and General Support Computer (PGSC) on-board the Orbiter.
