A programmable data link module is used on a time division multiplex data bus and includes a system master clock signal. The module is functional as an input device, an output device, or both as an input and output device. It receives data from the data bus during a selected time slot for a selected number of frames to control output devices connected to it. The data link module includes a clock loss signal for generating an inhibit signal when a loss of the master clock signal is detected. The inhibit signal will prevent any changes to the state of the output device during the duration of the loss of the master clock signal.
