A DB-9 female connector cable receives power and provides the control connections
for the R256 Controller. The DB-9 cable has a 3 pin connector provided for the
converter card in order for the controller to communicate with the PC via RS232 or
USB. The remaining 6 wires are for power & controls, allowing the user to solder and
program the switch push button and the Opto Sensor, enabling several options. The
I/O’s will allow for options such as solenoids, relays, opto isolators, LED’s and many
other input and output connections. See Table 2 below for details.
