3.7.3 Infrared input provides a ground reference connection (-). For
optimum infrared signal transmission, this ground reference should
connect to the IFR-9A or IFR-485 module being utilized.
3.7.4 The three (3) address strap pins are able to be connected to the
strap common. This provides strapping configurations, allowing up
to four (4) identical units to be individually controlled on a system.
The RS-485 sub-address of each player in the unit is set by
strapping the appropriate ID STRAP pin to ID STRAP COMMON.
Each connector must have a unique strapped ID for proper control
of this unit via the RS-485 data bus or IR interface.
If both connectors are strapped with identical sub-address, the 2
individual players default to sub-address 0 and 1 respectively.
The RS-485 sub-address of this unit is based on ID Strapping as
suggested below:
ID Strap 4 ID Strap 3 ID Strap 2 Sub-Address
0 0 0 0
0 0 1 1
0 1 0 2
0 1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7
Note: A value of 1 indicates the associated ID STRAP pin is
connected ID STRAP COMMON. A value of 0 indicates the
associated ID STRAP pin is a No Connect.
3.7.5 The J3 and J4 video output connectors provides video outputs to
the video distribution system.
