USB-7230/7250 2 Getting Started WARNING: The appropriate driver must be installed before connection to the computer system. See Section 1.5: Software Support for driver support information. 2.1 Unpacking Checklist Before unpacking, check the shipping carton for any damage. If the shipping carton and/or contents are damaged, inform the dealer immediately. Retain the shipping carton and packing materials for inspection. Obtain authorization from the dealer before returning any product to ADLINK.
NOTE: The USB-7230/7250 module is exclusively powered by the USB port and requires 400 mA @ 5 V. If the USB-7230/7250 module cannot be detected, power provided by the USB port may be insufficient. 2.3 Device ID A rotary control on the rear of the module (as shown) controls device ID setting and can be set from 0 to 7. The device ID allows dedicated control of the USB-7230/7250 module irrespective of the connected USB port.
USB-7230/7250 All remaining hardware configuration is software programmable, including sampling/update rate, input/output channel, input range, and others. Please see the UD-DASK Function Reference manual for details.

USB-7230/7250 3 Operations Figure 3-1: USB-7230 Functional Block Diagram The USB-7250 provides 8CH optical isolation digital inputs, 8CH relay outputs (4CH form C and 4CH form A), and 2CH frequency/event counters.
Figure 3-2: USB-7250 Functional Block Diagram 3.1 Isolated Digital Input The USB-7230/7250 support 16 or 8 opto-isolated input channels,as follows, with digital input first routed through a photo-coupler (PC3H4), and normal input voltage range for high state from 5 to 24V.
USB-7230/7250 Figure 3-3: USB-7230 Isolated Input Figure 3-4: USB-7250 Isolated Input 3.2 Change of State (COS) Detection COS (Change of State) refers to input state (logic level) changing from low to high or vice versa, wherein the COS detection circuit registers the edge of the level change.
In the USB-7230/7250, the COS detection circuit is applied to all DI channels, with the channel(s) to enable COS detection selectable by software. When an enabled channel changes logic level, the COS detection circuit generates an interrupt request to the USB microcontroller, which, when detected, latches corresponding DI data into the COS latch register.

By default, when enabled, the input channel ignores signal changes from one state to another when not remaining in the state for a pre-defined period. The digital filter function is applied on all DI channels and counters, with the default setting disabled.

Figure 3-12: Form C Relay Figure 3-13: Form A Relay Form C relays have NC (Normal Close), NO (Normal Open), and COM (Common) contacts. The COM terminal, located in the center,must contact either the NO pole or NC pole.
A relays have only NO (Normal Open) and COM (Common) contacts. When the control bit is high (1), the COM terminal znd NO pole contact. If the control bit is low (0), no contact takes place. Current relay output status can be read back by software, and during normal power up, reset, and power down (ejection from USB port), the relay is low status. In addition, USB-7250 also features programmable power-up output status, providing output state when powered up.
