KRAMER: SIMPLE CREATIVE TECHNOLOGY

Connecting Your SP-11D Digital Video Processor

6.1 Connecting a PC

You can connect to the unit via a crossed RS-232 connection, using for

example, a PC. A crossed cable or null-modem is required as shown in

method A and B respectively. If a shielded cable is used, connect the shield

to pin 5.

Method A (Figure 2)—Connect the RS-232 9-pin D-sub port on the unit via

a crossed cable (pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5) to the

RS-232 9-pin D-sub port on the PC.

Note: There is no need to connect any other pins.

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 3

)—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.
