Extron 100/200 Matrix Switcher

Description:

This driver controls the Extron series 100/200 Matrix Switcher. The 100/200 series switcher supports several different configurations, depending on the number of input/output boards installed and types of boards installed. The driver will automatically query the unit and determine the number and types of boards installed and declare the required fields accordingly. The switcher can have the following configurations:
4x4, 8x4, 4x8 or 8x8 Inputs x Outputs
RGBSVA (RGB + Sync + Video + Audio), RGBHVA (RGB + Horiz Sync + Vertical Sync + Audio), RGBVVA (RGB + Video + Video + Audio)
The switcher can be missing any of the above boards with the exception of the RGB boards needed for component switching.
Once the driver queries the switcher and determines the configuration, fields are generated that allow for assigning any input to any output or all inputs to an output. The Switcher operates such that it is really three switchers in one as each set of inputs (RGB or H or V or A) can be assigned independently to different outputs.

Quirks and Limitations:

Currently this driver supports all known configurations of the 100/200 switcher but has only been tested on a few. Also, even though the individual R-G-B inputs could be assigned to different outputs, this driver treats them as one set of inputs so that RGB acts as one input set.
Finally, on one of the units tested, the Power Off command would send the unit into a state of continually broadcasting garbage knocking the driver offline. Therefore, the Power off command may be suspect.

Connection Details

The parameters are 9,600 baud, 8 bits, one stop bit, no parity. The connection is a standard straight through cable and a 3 wire should be fine.

Driver Fields

This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...
The ? symbol in the fields represent the input/output number, so there will be versions of that field with the zone numbers 1 through 4 or 1 through 8 depending on the boards installed.
Name Type R/W Description/Limits
RGBOutput? Card R/W Read or Write the RGB Input assigned to this Output, where ? is the Input from 1 to 4 or 8.
HOutput? Card R/W Read or Write the H/V (Horizontal Sync or Video) Input assigned to this Output, where ? is the Input from 1 to 4 or 8.
VOutput Card R/W Read or Write the V/V (Vertical Sync or Video) Input assigned to this Output, where ? is the Input from 1 to 4 or 8.
AOutput? Card R/W Read or Write the Audio Input assigned to this Output, where ? is the Input from 1 to 4 or 8.
AllOutput? Card W Write all Inputs assigned to this Output, where ? is the Input from 1 to 4 or 8. This command assigns all available Inputs (RGBHVA) to the particular Output.
Power Boolean R/W Read or Write the power state of the unit.
