AOM2 High-Resolution Analog Output Module The AOM2 High-Resolution Analog Output Module is available in two versions. The AOM211 has one channel, while the AOM2/2 has two channels of analog output. Each channel has a separate D/A converter. Unipolar and bipolar ranges are switch-selected independently for each channel. The converters provide true X-bit resolution with a maximum nonlinearity of stO.OOl5% and low temperature coefficients. The AOM2 module also supports the system strobe feature, which allows any number of output channels to be updated simultaneously. Signal connections are made directly to screw terminals located on the module itself. The AOM2 module may be placed in any slot in the baseboard. To install the module, first turn off power and remove the top cover. Insert the module into the desired slot with the component side facing the power supply. Place the AOM2 as far away from the power supply as possible. CAUTION: Always turn off the power when installing or removing modules. To avoid ' the possiblity of EMI radiation, never operate the system with the top cover removed. User-Configured Components Each channel of the high resolution AOM2 module has a range selection switch, op- tional filter capacitor location, and screw terminal for signal connection. In addition, channel 0 or channel 1 may be connected to the AN OUT baseboard path. See Table 1 and Figure 1 for a summary of user-configured components on AOM2. The range-selection switch sets, Sl.01 and SlO2 (AOM2/2 only), can be set for two out- put ranges; *lOV and 0 to +lOV. Optional filter capacitors help preserve the converter's X-bit accuracy through the reduction of noise. Screw Terminals for both converters are located on a single bank, with a common ter- minal for ground connection. Jumpers select whether channels 0 or 1 are connected to the analog output signal path, and allow shorting of the output resistor for each channel. Document Number: 500-930-01 Rev.
