IOS module documentation for configuration and assembly which is accessed via data transfers in the "ID Read" space. instructions. Model IOS-440 digital input boards have no 8-bit I/O - Port register Read/Write is performed through 8- hardware jumpers or switches to configure.
The I/O space may be as large as 64, 16-bit words (128 Modules. bytes) using address lines A1..A6, but the IOS-440 uses only a portion of this space. The I/O space address map for the IOS- Note that the inputs of this device are bipolar, and may be 440 is shown in Table 3.1.

Bits 0-5 of this register are not used. Bits 6 & 7 of this register are used to indicate the bank of registers to be On the original IOS-440, this register was used to select the addressed. In Enhanced Mode, three banks (banks 0-2) of eight 8MHz IOS clock for debounce.
ID PROM bytes are addressed using only the even connection with each other. Separate commons are provided for addresses in a 64 byte block. The IOS-440 ID PROM contents each port to facilitate port-to-port isolation. A high signal is are shown in Table 3.2.
The following example outlines the steps necessary to FPGA input and does not include the opto-coupler delay. You configure the IOS-440 for Enhanced Mode operation, to setup can combine debounce with event sensing to obtain “glitch-free” event-generated interrupts, configure debounce, and read and edge detection of incoming signals for all 32 channels.

Channels are isolated from each other in directly for technical assistance via telephone or FAX through the groups of 8. There are 8 channels to a group or port. Because numbers listed below.
