General:
The smart carrier board is the heart of most RI fixtures and has many advantages over its passive counterpart.
For example the smart carrier board provides four control lines for each of its module locations (eight for the 12RF and 10 for the 20RF styles). The passive carrier board does not. Also the smart carrier board provides for clock, strobe, read, and write on two of its ten module positions (M1 and M5). This provides for the control of fixture modules and functions that require more than simple static digital control.
Switch Field Command Types:
1. Basic Static Digital - Examples include SPDT and SP4T switches, Enable/Disable funtions on modules,
divider ratio selections, and programmable attenuator settings.
- When writing to a Smart Carrier module control line the format is of S#10X1
S = S, # = Module number being written to (M1-MA), X = 1, X, or 0.
Bit position = S# DS1 DS2 DS3 DS4
Ex. The string S6XX01 would drive DS3 low ( 0.0V ) and DS4 high (3.8V) on the fixture module placed at the physical location of M6 on the smart carrier.
When writing to a standard Cbit ( found on the fixture carrier board ) the format is of CXY
C = C, X = control bit used, Y = 1 or 0.
1 = Open
0 = Closed
Ex. C20 Sets the standard Cbit#2 low. To combine this with a Smart Carrier control string, add it to the front of the overall string. The string C20S6XX01 sets standard Cbit#2 low, sets DS3 low, and sets DS4 high on the fixture module found at M6.
When writing to a module requiring an "A" type command the format is A#SW=N+alpha
A=A for action, # = Module number being written to (M1-MA), N+alpha = a number plus letter
(Ex. 16a) which refers to a specific configuration of the module.
4. "M" Type Commands: Please see specific module specifications (Cbit Expander module).
Module Placement Selection Criteria:
Socket Functionality | Select Socket | Command Types | Examples | Also Supported |
Modules requiring a high speed clock (400KHz) or register writes | M1,M5 | "S" type, and "M" type S3 used as clock in high speed clock applications. | High Speed Digital Fixture Mux | All other Fixture Modules |
Modules requiring static data sets to set config. Includes register writes. | M1-M8 | "S" type, and "M" type | Switches and Attenuators Fixture Mux | All other Fixture Modules not requiring a high speed clock input. |
Subset of normal socket functionality. Does not include register write commands ("M" type). | M9&M10 super smart carrier only (Y00065A) | "S" type only. | Switches and Attenuators Excludes all modules needing "M" type control. | Fixture Mux and Cbit Expander modules will not work here. |
