Log Data Output Request

The VS-900 Log Data Output allows you to monitor most station and system activity. Send the string below to initiate Log Data flow from individual or multiple exchanges simultaneously. Once the data stream has been initiated, the VS-900MF will continue to send the log data without re-sending the request.

After the initial Log Data Request, the VS-900MF will send an enquiry (DLE & ENQ, 10H & 05H) to the PC when log data is available in the queue. The PC should then respond with an acknowledgement (DLE

&ACK, 10H & 06H) so the log data will be sent from the VS-900MF. This process will repeat until there is no information left in log data queue.
