Application Note 65
Quartz Routing Switcher Remote Control Protocol
Revision 1.4 Page - 17
4. RESPONSES
4.1. ACKNOWLEDGE
Acknowledge is used as a no error response to some messages:
.A(cr)
4.2. ERRORS
If an error is detected in any sequence prior to a (cr), the matrix replies with:
.E(cr)
4.3. POWER UP
At power up or reset the matrix outputs a (cr).P(cr) to inform a remote computer that the matrix is now on-
line.
4.4. UPDATE
If any routes are changed in the matrix, either by remote panels or the remote control protocol, the matrix
replies with an update message for each route changed. For a normal take, where the destination and
sources are routed on the same control level updates are of the form:
.U{levels}{dest},{srce}(cr)
The response message always replies with levels in the following order: V,A,B,C,D,E,F,G…
4.4.1. Tieline Update
This type of update was used exclusively on the SC1000 controller. The SC1000 is obsolete.
Since a tie-line take has a different level for the destination as for the source then the level information
is included as;
.U{dest level}{dest},{ {srce level} ORed with {srce} }
In this circumstance there will be only one level defined for the source and destination. The source value
will contain both the source number and the level from which it has been routed to.
When the source number is represented in hexadecimal, the lower 12 bits of the source value define the
source number (this gives the source number a range of 1-4095). The next 5 bits define the level value
(between 1 and 31) of the tieline source.
