NOTES: 1 - If an input is received that is outside the allowable limits for a command, bit 3 shall

be set for the response to that command only. Once the response to the

command has been sent to the host, bit 3 shall be cleared again.

2 - This bit is set in response to a calibration command if an error occurred in the respe

ctive operation.

Example:

1. The CAP 2000 has been turned on with the proper cable inserted in the serial port placing the

unit in its external mode.

2. The host computer sends an I. The CAP 2000 responds with an ICAPHI10000 indicating a

high temperature CAP 2000 with version 1.00 firmware and a status byte of 0.

3. The host sends a T190. The CAP 2000 begins controlling to 40.0C and responds with T01.

4. The host sends V1F4. The CAP 2000 ramps to 500 rpm and responds with V03 indicating the

motor is running.

5. The host sends a T9C4. The request to control temperature to 250.0C is illegal. The CAP 2000

responds with T0B indicating a temperature request outside the limits of the instrument.

6. The host sends an R. The CAP 2000 responds with R002B1115950A25A83E80103 indicating

a viscosity reading of 110.25 Poise, a torque reading of 55.25%, a shear rate of 6650 1/sec, a

sensed temperature of 100.0C, and a number one cone. Note that bit 3 of the status byte has

been cleared. It is set only in response to the offending command (T9C4) and is cleared as soon

as the response is issued.
