Cable Box Testing with DeviceMaster


A cable company was testing diagnostic ports on their cable boxes. These diagnostic ports connect a television to an external signal, and turn the signal into television content for your home television set. These diagnostic ports also activate if there is a problem with the cable box, and diagnose problems if failure occurs.

99040_6_DMSH8_bklfThe company needed a testing system that would ensure that their products were being tested accurately, and went to Comtrol. Comtrol recommended their DeviceMaster serial hub.
