KATC-C1 Instructions Page 15 04/14
Serial Port Baud Rate
The Serial Port is set to communicate at 9600 baud. Other communication parameters are: eight (8)
data bits, no parity, and two stop bits.
Remote Commands
For true remote operation, your computer can send commands to the KATC-C1. These commands
can cause the KATC-C1 to perform various functions including: run-down of the test current, initiate
a measurement, transfer of test result data to the computer, and a quick transfer of test current to the
computer.
The commands consist of four (4) bytes of ASCII data and are formatted as follows:
<any character><Z><command character><CR> where,
<any character> indicates that any ASCII character may be used to start the command,
<Z> indicates that the second character of the command must be a "Z" (5A
hex),
<command character> indicates the desired command (taken from the following list),
<CR> indicates a carriage return (0/D hex) and specifies the end of the com-
mand.
Following is a list of commands which can be sent to the KATC-C1 from a remote computer.
Command Character Description
H This command is the same as pressing the Hold/Rundown push-
button. It causes the KATC-C1 to hold the test results in the display
and initiate a rundown of test current (if the KATC-C1 rundown out-
put is connected to a motorized variac ā as in the Type KCTS Test
System).
M This command is the same as pressing the Measure push-button. It
causes the KATC-C1 to begin taking measurements. It is usually used
at the start of a test or after a Hold or Print command has been issued.
P This command is the same as pressing the Print push-button. It causes
the KATC-C1 to send a copy of the displayed test data to the computer
through the serial port. This command sends a full copy of test data in-
cluding heading information, as shown in the next section.
