MC-8 Serial Communications Protocol
Line1

Max Length:
Line2
Data Type:
Max Length:
The MC-8 includes 8 custom characters that are defined to display increments of a display block. (i.e. Volume Bar)
The custom characters are ASCII character codes 8E - 93(hex). The codes are used as follows:
'8E' - empty cell
'8F' - left 1 bar
'90' - left 2 bars
'91' - left 3 bars
'92' - left 4 bars
'93' - full cell
6.1.3.3 HOST Response
The MC-8 does not expect any response from the HOST.
6.1.4 MC-1 Parameter Change
MC-8 will transmit predetermined parameter change notifications. If a parameter value is changed due to any user
action or system action the MC-8 will transmit the current value of the parameter that is changing.
This command has been maintained for backward compatibility with MC-1. In order to maintain backward
compatibility, the MC-8 Parameters have been mapped to the MC-1 parameters as described in the Supported
System Parameters table listed below.
MC1 Parameter Change Notification can be enabled/disabled by using the Communication Configuration Packet as
described in
6.3.19 Get Communication Configuration
The MC8 disables these notifications in its default state.
