DlOl Digital Input/Output Module The DIOl Digital Input/Output Module 1 provides 32 programmable digital inputlout- put channels at LS-TTL levels. These channels are grouped into &bit ports, and each port can be individually programmed for input or output by on-card DIP switches. Rapid settling times allow sampling of high-speed digital inputs. Outputs are latched to allow asynchronous reading of the output data. I/O connections are made to on-card screw terminals, which accept 16-24 gage wire leads. In addition to the screw terminals, a jack is provided for quick connection and disconnection of inputs and outputs. The DIOl module can be installed in any available slot in the system; however, digital modules should generally be placed in the high-numbered slots if any analog modules are present in the system. To install the module, remove the baseboard top cover and insert the module into the desired slot with the component side facing the power supply. CAUTION: Always turn off the baseboard power before installling or removing modules. Replace the top cover and secure it with screws. To avoid the possibility of EM1 radiation, never operate the system with the top cover removed. User-Configured Components User-configured components for the DIOl include the input/ output connections and the I/O programming DIP switches, as listed in Table 1. Connections can be made either to screw terminals at the top of the module or to a separate on-card jack, which allow s the quick connection and disconnection of I/O lines. Input/output programming of each of the four ports is performed by setting DIP switches located on SlOl. for the location of these components, refer to Figure 1. Table 1.
