The Headend Satellite Receiver can be operated and monitored remotely via the
EXPANSION port when connected to a PC workstation or data terminal. Remote
receiver operation requires installation of a PC/data communications program.
Note that certain program settings may vary, depending on the type of worksta-
tion/terminal equipment being used. Data interface cables connected between the
Headend Satellite Receiver and some customer equipment may require a unique
pin-out for proper operation via the EXPANSION port (DB-25 female connector).
For port pin-out information, see the accompanying table. Note that only those
EXPANSION port pins used are shown (i.e., all other pins are unused, or are not
required for normal operation).
