accQcomm Interface Module

Appendix A Commands, Constants, and Registers

A.1 Program Commands Teledyne Isco recommends using the accQcomm configuration

software to configure the accQcomm.

The following section is intended for use when configuring the

accQcomm using a terminal emulation software such as Hyper-

Terminal, instead of the accQcomm Configuration Software. All

program commands are listed in Table A-1.

To correctly program the accQcomm, enter all commands first,

then save them to the unit’s internal flash using the SS

command. Afterward, restart the accQcomm with the SR

command. The new settings will be applied upon restart.

Commands and Definitions Functions

Maximum bad readings

Param 1 (Range – 255): Defines the maximum number of bad data read-

ings before the current data is cleared from memory. The counters for bad

flow, bad velocity, bad depth, and time-outs, are compared to this value.

Enable/Disable analog output channels

Param 1 (Range 1 to 0): Channel 1 state: 0 is disabled and 1 is enabled.

Param 2 (Range 1 to 0): Channel 2 state: 0 is disabled and 1 is enabled.

Param 3 (Range 1 to 0): Channel 3 state: 0 is disabled and 1 is enabled.

Param 4 (Range 1 to 0): Channel 4 state: 0 is disabled and 1 is enabled.

NOTE: The number of parameters is always 4, even if the system has less

than four analog outputs. If a given output is not installed, that command

has no effect.

Example — Enables analog output channels one and two, disables three

and four.

?>AE 1 1 0 0

Analog channel range

Param 1 (Range 1 – 4): The analog channel being set.

Param 2: The instrument being assigned to the channel. Valid values

include numbers 1 to 3, Ins1, Ins2, Ins3, and Sys (used for averages and

summed flow).

Param 3: The data type that is assigned to the channel. Valid values include

Flow, Velocity, Depth, Temperature, Voltage, AvgDepth, SumFlow, etc. The

numerical data type constants in Table A-2 can also be used.

Param 4: The low range of the analog span; must be in internal units for the

data type specified.

Param 5: The high range of the analog span; must be in internal units for

the data type specified.

Example — Assigns analog output 1 to instrument 1 level; sets span from 0

to 2 meters:

?>AR 1 Ins1.Level 0 2000
