Connecting Your FC-400 Time Base Corrector/Synchronizer

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.
