have been configured to supply +5VDC power to pin 9 of their DB9 connector. COM3 and

COM4 may supply up to 0.5A of current; do not exceed this limit.

Note: COM3 and COM4 may also be configured for pin 9 to be RI (ring indicator) or to

supply +12V 0.5A. This configuration must be performed at the UTC RETAIL facility.
