5.7.1 Command ’c’- Sub-command Index 00: Configure a Host Delivery Stream

This sub-command is used to configure the principle parameters of each of the three possible concurrent host delivery streams, one at a time. Following this configuration phase, the particular stream (1, 2, or 3) or all streams (0) may be started, stopped, altered, or undefined, with other sub-commands. This sub-command’s format is:

 

Command

 

 

"c 00 st pppp sync per f num"

 

 

 

 

 

’c’ is the operation code

 

 

 

 

 

’00’ is the sub-command index (ii) for configuration

 

 

 

 

 

’st’ is the stream id digit (1, 2, or 3)

 

 

 

 

 

’pppp’ is a 1-4 hex digit position field (channel

 

 

 

 

 

selection bit map)

 

 

 

 

 

’sync’ is sync type character (0= hardware trigger

 

 

 

 

 

or 1= clock)

 

 

 

 

 

’per’ is the period (if sync=0: # of trigger periods or

 

 

 

 

 

if sync=1: delay timer period in msec).

 

 

 

 

 

’f’ is the format of each acquired datum in stream

 

 

 

 

 

’num’ is the number of scans delivered in the

 

 

 

 

 

stream

 

 

 

 

 

(0=unbounded, >0 bounded).

 

 

 

 

 

NOTE: all parameters are separated by a space

 

 

 

 

 

character.

 

 

 

 

 

 

 

 

Response

 

 

"A" or "Nxx" ’A’ for acknowledge; ’N’ for negative

 

 

 

 

 

acknowledge, error code xx.

 

 

 

 

 

 

 

 

Autonomous

 

 

none generated (until Stream Start sub-command)

 

 

 

 

 

 

Packet

 

 

 

 

 

 

 

 

 

 

Description: Configures a particular stream (‘st’) to deliver data scans autonomously to the host, with each scan containing selected acquired data for the channels specified. The channels are specified by a standard 16-bit position field bit map (encoded pppp as a 1-4 hex digits). A separate sub-command (ii=05) may be used to select which acquired data groups or prefixes are included in each stream. By default, only Temperature/Resistance (EU) data group is selected (if ii=05 sub-command is never executed for the stream after its initializing ‘c 00’ sub- command).

The generation of individual scans of a stream may be synchronized with either an external user-supplied hardware trigger or a periodic (1000 Hz) clock interrupt generated inside each module. This choice is made with the sync type ‘sync’ parameter (a single digit) where: 0 = synchronize with hardware trigger; 1= synchronize with the periodic clock.
