Chapter 7: sDIO Module WARNING: Remove power from the controller before plugging in or unplugging any IEEE-1394 cables to SmartServo IEEE-1394 con- nectors. Failure to remove power could result in unpredictable beha- vior by the system. 5. Connect a user-supplied ground wire to earth ground on each sDIO module. 6. Connect the 24 VDC input power to the controller. 7.3 sDIO Module Connectors and Indicators 1 R LINK 1.1 1.2 XDC1 XDC2 X3 IEEE-1394 X1 X2 X4 24V 0.5A *S/N 3563-XXXXX* SC-DIO OK SF - + - + 2 3 7 4 5 6 Figure 7-5. sDIO Connectors and Indicators 1. Status LEDs . Two LED s indicate link status of the IEEE 1394 connection and system status. LINK :
Green LED = communication with another device over IEEE 1394 connection OK. OK/SF : Red LED = output driver fault detected due to excessive temperature or current (output is automatically shut down), solid green LED = communication with controller OK, blinking green = not configured in software. 2. IEEE 1394 ports : Connects to one of the SmartServo ports on controller or IEEE 1394 ports on additional sDIO modules. 3. X1 Output: 44-pin female D-sub connector, for digital output signals 0033-0048. 4. X2 Output : 44-pin female D-sub connector, for digital output signals 0049-0064. 5. X3 Input : 26-pin female D-sub connector, for digital input signals 1033-1048. 6. X4 Input :
26-pin female D-sub connector, for digital input signals 1049-1064. NOTE: For installations that use two or more sDIO modules, the above signal num- bers apply to the signals for the first sDIO module. See Modifying the Default sDIO Configuration on page 62 for information on configuring more sDIO modules. 7. Two 24 VDC connectors : Connect power from the unused XDC connector on the SmartController to the XDC1 connector on the sDIO module (see Connecting Power on page 19 for power specifications).
