Connecting Your SP-10D Digital Video Processor
11
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4
to 6 on the controller side.
Method B
(
Figure 4
)—Connect the RS-232 9-pin D-sub port on the unit via
a straight (flat) cable to the null-modem adapter, and connect the null-
modem adapter to the RS-232 9-pin D-sub port on the PC. The straight
cable usually contains all nine wires for a full connection of the D-sub
connector. Because the null-modem adapter (which already includes the
flow control jumpering described in Method A above) only requires pins 2,
3 and 5 to be connected, you are free to decide whether to connect only
these 3 pins or all 9 pins.

DIP-switch settings are defined in
Table 3
and
Table 4
:
Table 3: DIP-switch Settings
DIP-Switch
Set as Follows:
1
Pedestal
ON for pedestal of output signal (7.5 IRE offset selection for NTSC); OFF for no pedestal
2
HsVs/Cs
ON for Composite Sync on outputs Hs/Cs and Vs/Cs; OFF for Horizontal Sync on
Hs/Cs, and Vertical Sync on Vs/Cs outputs
3
Secam VBI
ON for insert identification signals occupying 9 lines of field-blanking period (only for
SECAM output standard) (bottle pulses); OFF for no insert (no bottle pulses)
4, 5, 6 Test Signals The status of these DIP-switches defines the test signal: see
Table 4
7
AGC
ON for enabling automatic gain control; OFF for disabling automatic gain control
8
