LVS MODE - COMMUNICATING WITH A PROFILE DISK RECORDER
When the HD9010-SIE is in one of the LVS modes, the receive input of the COM1 serial port is used to
listen to a serial data stream from the Profile disk recorder. The Profile sends status, LVS scene and
CTL information out to multiple devices that are connected in a 'daisy chain' to the Profile's serial port.
In order to properly address each of the HD9010-SIE units connected, the Profile sends out an
'address' before each command. The LVS ADDRESS menu item on the Utility menu must be set to
match the address that the Profile is using for a specific output. (See section 3.8.7).
4.2.1. Data Format
The COM1 serial port is used to listen to RS-232 commands from an LVS device.
communications protocol runs at 9600 baud, 8 bits, and no parity.
4.2.2. Message Block Format
All command values, arguments and data values shown are expressed in hexadecimal
format unless otherwise noted.
Each message block starts with the ESC (1BH) and is structured as follows:
