Satellite IF Switch
Table 1 shows the coherence between the terms used
by the DiSEqC standard and the pin names used by the
MAX12005 along with the command sequences used to
control switching.
Table 2 lists the supported command bytes. The com-
mand byte is the 3.byte in the DiSEqC master frame
(refer to the DiSEqC Bus Functional Specification ver-
sion 4.2, top of page 13). The DiSEqC slave only sends
Table 1. DiSEqC Slave Control Interface
a reply if requested by a framing byte 0xE2 or 0xE3
in the master frame (refer to DiSEqC Bus Functional
Specification version 4.2, bottom of page 13). All DiSEqC
commands control the contents of the DiSEqC registers
described in chapter 7.1.
Table 3 lists the supported command bytes. The DiSEqC
commands are internally mapped to individually named
registers. The registers do not have an address.

Note 1: The primary device outputs connect directly to the satellite receivers. The secondary device outputs connect to the primary
device through the cascade inputs. Also see Figure 1.
Note 2: Only those DiSEqC commands that differ between sequences have to be sent to change the input, not all four commands.
By default RFIN1 from the primary device is selected.
The DiSEqC interface is designed according to the DiSEqC Bus Functional Specification version 4.2.
