#In #Out
Enter the number of inputs and outputs for this logical level.
For Venus video switchers, the maximum for one logical level is 1024 in and out.
For Venus audio switchers, where the left and right channels are assigned to different levels, the maximum number of
inputs is 512 per level; the maximum number of outputs is 1024 per level. For example, these values would apply to
a Venus analog audio switcher configured for stereo operation (the usual case) and to a Venus ES 401 digital audio
switcher configured for two−level stereo operation.
For Venus analog audio switchers configured for mono operation, ES 400 digital audio switchers, or ES 401 digital audio
switchers operated in 1−level stereo mode or mono mode, the maximum number of inputs and outputs is 1024.
Special entries are required if Output Monitoring is being used (see Appendix O).
For Venus DM 400B Data Matrix switchers, the entry for “#In” and “#Out” should be set to the actual number of inputs
plus 1 to allow an extra number for the “SAFE” input. For example, if the switcher is 64 x 64, both entries should be
“65.” (A DM 400B matrix is always square.) The maximum is 192 in and out.
Mars switchers, which use octal architecture, will require special entries. When the binary driver is used (as described
in Step 11 below), then the “#In/#Out” entries are as follows:
Switcher size No. of inputs (as entered on table) No. of outputs (as entered on table)
24 x 8 64 16
For the maximum number of inputs/outputs for remote (third party) switchers, refer to the manual supplied with the
switcher.

Enter the physical (hardware) level number.
This is the level address determined by hardware switches on the switcher itself. These are normally set at the factory
and rarely changed in the field. Refer to the following list and the hardware manual supplied with the switcher for more
information.
A physical level number can range from 1 to 999; however, the maximum number of logical levels is still 96. This num-
ber may be reduced according to the number of outputs being controlled. For more information, see page 1−16.
