Motor Driver Connectors (J11 through J22)
These connectors provide for up to four Gecko Stepper Driver modules. Gecko stepper drivers may be
installed on these sets of connectors in any combination. The only restriction is that the step and
direction signals from the PC’s parallel port are hard wired to specific connectors, as shown in Table 7 on
page 16.
