Flexible I/O - MCi iControl User Manual

• Node Response test
1. Insert a probe wire into pin 20, connect the positive voltmeter lead.
2. You should see 5-volts, +/- 10%. Leave the probe wire in place.
3. Bend the wire/jumper and short pin 20 to pin 17.
4. Insert a probe at pin 5 and connect the positive voltmeter lead.
5. You should see something under 1-volt.
6. Leave the pin 20 to pin 17 jumper in place and the positive voltmeter lead connected to
pin 5.
7. Use a second jumper to short pin 10 to pin 12.
8. You should see something over 20 volts.
9. Leave the pin 20 to pin 17 jumper in place. Remove the lead from pin 5.
• Driver output voltage test
1. Place the positive DC voltmeter lead on the Hall Call Bus SHCS Terminal.
2. You should see something over 35-volts.
3. Insert a probe wire at pin 16 and connect the positive voltmeter lead
4. You should see something over 25-volts.
5. Leave the pin 20 to pin 17 jumper in place. Remove the lead from pin 16.
• Node control flag test
1. Insert a probe wire at pin 18 and connect the positive voltmeter lead.
2. Bend the wire probe and temporarily short pin 18 to pin 17 or pin 15.
3. Watch the voltmeter as you unplug the wire from pin 17 (or 15), it should read less than
1-volt when the short is released.
• Node control flag test preferred alternate method
1. Install a ¼ Watt 10K Ohm (brown, black, red) resistor between pin 15 and pin 18 and
connect voltmeter to pin 18.
2. Release pin 20 from the ground (pin 17). The voltmeter should read something over 20-
volts.
If the preferred alternate method is used you will see a short positive pulse on your voltme-
ter.
1. Place the positive DC voltmeter lead on the Hall Call Bus SHCS Terminal. The voltmeter
should indicate less than 1-volt.
2. Remove all test connections. If the driver passed all of the above tests it will likely oper-
ate OK.

Flexible I/O

iCue makes extensive use of a serial bus to handle a range of communication and control needs.
The serial bus is used to service the MCE Serial Hall Call System and to control I/O through one
or more SC-ION boards (input/output expansion boards). Each SC-ION board provides 16
user-configurable inputs and 16 user-configurable outputs. Input and output configuration,
using the MCE iView graphical user interface, is described in Section 6 of this guide. This sec-
tion describes physical I/O connections.
