SCM-301-2, CAMAC SCSI Crate Controller

[Download the SCM-301 Manual in PDF]

A high performance FASTCAMAC Level 1 interface designed to attach to the SCSI bus.

The SCM-301-2 allows a CAMAC Crate to be controlled by the widely used Small Computer System Interface (SCSI) Bus (ANSI Standard X3T9.2). Multiple crates may be attach to the same SCSI bus of any Linux PC, OSX Macintosh or Windows PC.

The standard SCM-301-2 implements all the features of the IEEE type A1 Controller, with the exception of multicrate operations, for which there is no provision in the SCSI Standard.

The SCM-301-2 includes level 1 FASTCAMAC features. The F(5) read command can transfer data from a FASTCAMAC-capable target module at up to 7.5 megabytes per second across the dataway. FASTCAMAC block transfers terminate on no-Q or transfer-length-satisfied.

The SCM-301-2 contains a 24-bit LAM mask register, which may be enabled by a switch. When enabled, only LAMs from stations corresponding to a set mask bit will be returned by a Read-LAM-Pattern, N(30)A(0)F(0), command. If the switch is off, all LAMs will be recognized. CAMAC data acquisition with the SCM-301, SCSI controller is supported by the Kmax software environment also available from SPARROW.
