MATRIX ROUTING SWITCHER

replies to instructions 10 and 11 are as per the definitions in instructions 7 and 8 respectively. For
example, if the present status of machine number 5 is breakaway setting, then the reply to the HEX
code
0Bh

80h

80h

85h

would be
4Bh

80h

81h

85h

NOTE 3 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or
if a parameter associated with the instruction is out of range (e.g. trying to switch a 16x16 matrix with
an input or output greater than 16, or trying to switch an input or output greater than the highest one
defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is
being programmed via the front panel. Reception of this code by the switcher is not valid.

NOTE 4 – The output VCAs are 32 logarythmics steps. Values are 0 to 31 (decimal).

NOTE 5 – The input levels are 32 logarythmics steps. Values are 0 to 31 (decimal) and coded in the 5
lowest bits of the output byte.
When bit 5 = 0, the gain value is taken.
When bit 5 = 1, the Balanced/Unbalanced mode is taken : bit 6 = 0 for Balanced mode, bit 6 = 1 for
Unbalanced mode.
The reply always contains the Balanced/Unbalanced mode and the Gain value under the binar form :

1

bal/unbal

1

G4

G3

G2

G1

G0

Where bal=0 and unbal=1

the reply to the HEX code
16h

02h

85h

81h

would be (for a balanced mode)
56h

02h

A1h

81h

NOTE 6 – The Output VCAs are 32 logarythmics steps. Values (0 to 31 decimal) are replied in the
output byte.

The input levels are 32 logarythmics steps. Values are 0 to 31 (decimal) and coded in the 5 lowest bits
of the output byte.
The reply always contains the Balanced/Unbalanced mode and the gain value under the binar form :

1

bal/unbal

1

G4

G3

G2

G1

G0

Where bal=0 and unbal=1

the reply to the HEX code
19h

02h

00h

81h

would be (for a maximum VCA)
55h

02h

1Fh

81h

NOTE 7 – This code is reserved for internal use.

NOTE 8 - The serial number is replied as BCD code, with Most Significant Byte in the input byte and
Less Significant Byte in the output byte.

NOTE 9 – When OFF LINE mode, sending a switch instruction will store the data in the volatile matrix
memory, without effective switch. Switch will be done when ON LINE instruction.
When ON LINE mode, sending a switch instruction will execute normal switch.
