pixtype

Command:	pixtype
Contexts:	Network socket, serial console. Applies only if the CCD is an "OTA" device.
Function:	Tell the controller which pixel structure design the OTA has.
Required Parameters:	type=0|1|2|102|103
Optional Parameters:	dev=all|0|1

The following table explains the possible values for the type field:

0	The CCD is not an OTA, and can only shift "up" and "down"
1	The CCD has MITLL OTA Type I pixel structure
2	The CCD has MITLL OTA Type II pixel structure
102	The CCD is an STA with Type II pixel structure but STA phase wiring
103	The CCD is a newer STA device with yet another variation

If in doubt, it may be necessary to try all non-zero values. NOTE: For all MITLL CCID58, the correct form is:

pixtype dev=all type=1

as all MITLL devices made to date have Type I pixel design.

Notes:

Shifts along axis2 (the normal parallel direction) typically tend to function even if the pixtype setting is wrong. See also ot command.

If dev= is omitted, the last default dev applies (which can be either 0 or 1, but not "all").
