Operate CAMAC Instrumentation from the USB Bus
Since 1992 our popular Model 73A SCSI Crate Controller has been filling the need for an economical solution to controlling CAMAC instruments at the maximum CAMAC speeds. The SCSI bus has allowed connection to a wide variety of processors and operating systems. A recent development, the Model 12 USB/SCSI Exchange Kit provides an adapter which allows the Model 73A to operate from a computers USB port. Both new and existing Model 73A controllers can now operate from this popular USB bus.
*
Operates at USB 2.0 - enabled systems, supplied software allows USB Plug and
Play to identify
the Model 73A as a USB device.
* Easy
connection of CAMAC to PC and laptops- Electronics contained in sleek
SCSI Connector Hood
* Performs all the Model 73A operations.
* Based on Adaptec USB2XCHANGE hardware
Complete Model 12 kit consists of a USB2EXCHANGE USB to SCSI Adapter with 1meter cable, a Cable Adapter which allows extending the SCSI side via standard SCSI II cable (not included), and software for $140.

Expanded and Upgraded Model 221A
PULSE- DELAY- SEQUENCE GENERATOR
CAMAC MODULE less than $100 per channel
Our Model 221 Timing and Sequence Module whose versatility has enabled it to fill many instrumentation roles has now been improved. The new upgrade, the Model 221A features:
* Channel output changed from 12 to 16 channels
*
Memory increased to 512K words per channel, enough for a programmable
clock useful as
transient recorder clock.
* Maximum clock rates now 10MHz ( 0.1 microsecond resolution ) up from 1MHz
In Addition to the increase of memory size, channel capacity and resolution, new programmable features have been added. Previous models provided only a high TTL output for a programmed logic "1". Now the polarity of each output can be selected for a TTL high or low signal for a programmed logic "1". This makes it easier to program the reset or start initial value as either high or low.
The feature of programming a beginning and end time for a TTL logic "1" signal has been enhanced to include the capability of providing as an output the internal clock for the programmed logic "1" duration instead of the signal itself. This feature provides the capability of generating programmable bursts of clock pulses useful in selectively clocking transient recorders. A complete data sheet as well as a Model 221A programming guide are available in pdf form.

****** FASTCAMAC NEWS ******
7.5 megabyte per second with SCSI FASTCAMAC Controller
The popular Jorway Model 73A-2 can perform Level 1 Fast read CAMAC operations in accordance with the FASTCAMAC Specification document DOE/SC-0002, endorsed by the U.S NIM committee. With this feature enabled, the CAMAC cycle is expanded to consist of multiple S1 pulses at a nominal interval of 400 nanoseconds, terminated by a single S2 pulse. Used with a CAMAC module that is designed to transfer a CAMAC word on every S1, a transfer rate of 7.5 Mbytes/second for 24 bit transfers and 5 Mbytes/second is possible. The SCSI host adapter must be capable of transferring at least 10 Mbytes/second in synchronous SCSI mode. A FASTCAMAC level 1 block read is performed using CAMAC function code F(5). No modification of existing software is required.
FASTCAMAC Transient Digitizer: 6 Channel module with up to
1 megaword per channel can be read at 7.5 megabytes per second.
The Jorway Model Aurora 14, 1 MHz Transient Digitizer now includes as a standard feature the capability of accommodating Level 1 FASTCAMAC reads. With large memory capacity of 128K, 512k or 1 Megaword capacity, FASTCAMAC greatly enhances the speed of reading data. Two data formats are available, 12 bit words which can be read every 400 nanoseconds or packed data of 24 bits which can be read at the full 7.5 megabytes per second.
