9625LG Series Logo Inserters and Media Keyers Manual
The ports are also used to interface to the EAS Decoder (EAS optioned units) or optional
temperature probe. These ports can be individually changed to run in either RS422 or
RS232 mode by reconfiguring jumpers J19 or J20 on the 7700FC card inside the unit. The
SERIAL CONTROL C port is controlled with jumper J19 and the COM D port is controlled
with jumper J20. When they are set for the RS-232 mode of operation, the ports have the
same pinout as Port A (shown in Table 2-1). When they are set for the RS-422 mode of
operation the ports have the pinout shown in Table 2-3. The COM D port was not available
on early HD9625LG units.
The COM D port is not available on early versions of the HD9625LG
The RS-422 pinout for the SERIAL CONTROL and COM D ports is not a standard
SMPTE RS422 pinout. You will have to make a custom cable in order to use these
ports in the RS422 configuration.
The function of each port must be configured using the Serial Control and Com D menu
items on the GENERAL menu. (See section 3.6.5)

GPI/O
This 15 pin female high density 'D' connector contains several general purpose control
inputs and outputs. The inputs are used to connect manual or automatic triggers for the
display or insertion of media. The outputs provide feedback on internal unit status of the
keyer.
See section 2.9 for information on connecting the general purpose inputs and
outputs. For information on configuring the GPI functions, see the GPI Setup menu item on
the PRESET menu (section 3.8.1)
