The back of the BCOM-USB device has two DB-9 Male connectors and a Modem Power
connector. The +5VDC Modem Power connector (MDM PWR OUT) is only for powering the
ASE 2-channel Bell-202 Test Set Modem from the BCOM-USB device.

It is recommended that the Modem Power be connected to the BCOM-USB device prior to
connecting the BCOM-USB device to your machine.
The bottom of each BCOM-USB device contains a serial number which is used for device
registration and BCOM-USB license management. For certain support and upgrade situations,
you may be asked to provide this serial number.
