Using the Handheld Infrared Thermometer 2

2.3.13 PC Interface Commands

You can communicate directly from the PC to the infrared thermometer. Here are the Comm port settings and communication commands from the PC:

Baud rate: 9600

Data: 8 Bits

One Stop Bit

No Parity

All the PC commands to the infrared thermometer are case sensitive and terminates with a carriage return (CR). You can change parameter settings from the PC when data transmission is stopped.

Command	Description
(ASCII)
IR	Get the current infrared temperature from the thermometer
T	Start sending Data stings from the thermometer to the PC
P	Stop sending data to the PC
S	Reset Min, Max, Diff, Avg temperature values on the thermometer
F1 or F0	F1 = Set Engineering unit to °F , F0 = Set Engineering unit to °C
E95	Set Emissivity to 0.95 (Thermometer sends “E:95” back as
	confirmation)
H500	Set High Alarm set point (HAL) to 500 (It sends “HAL:500” back as
	confirmation)
L20	Set Low Alarm set point (LAL) to 20 (It sends “LAL:20” back as
	confirmation)
A125	Set Target ambient temp (AMB) to 125(It sends “AMB:125” back as
	confirmation)
t	Get the data transmission interval (PRN) from thermometer
t5	Set data transmission interval (PRN) to 5 seconds. Thermometer sends
	back “PRN:5” as confirmation.
p	Get the data transmission flag from the thermometer.
	PRNF:0 means no data transmission (PRN is disabled)
	PRNF:1 means data transmission (PRN is enabled)
D0	Start to download stored data from IR thermometer memory
De	Erase the data from the IR thermometer memory

Here is a typical data strings from the infrared thermometer to the PC when the “T” command is activated:

OS534; E:95; MAX:78; MIN:65; DIF:13; AVG:72; DIS:1144; HAL:900; TC:74; TEF:0;

LAL:20; AMB:125; PRN:5; PRNF:1; IR:73; CF:0; FF:1; LF: 0:
