Communication with the device requires terminal software installed on the
PC. User can use his favourite terminal software. This guide contains example how
to set up a connection with the device using PuTTY software with Windows 7
operating system.
Serial Protocol
Protocol allows user to set configuration parameters of the device or acquire
measured data using commands specified below. Each command is a set of ASCII
characters which may be followed by <CR> and/or <LF>.
Configuration command
Command template: <T
setpoint
P I D T

T
setpoint
[°C] – target temperature value. The device checks output temperature via
thermistor and manages output current to reach temperature setpoint.
P – PID proportional coefficient (in range from 0.0 to 20.0)
I – PID integral coefficient (in range from 0.0 to 20.0)
D – PID derivative coefficient (in range from 0.0 to 20.0)
T
min
[°C] - lower threshold which is checked by the driver (OC)
T
max
[°C] - upper threshold which is checked by the driver (OC)
Example: <10 4.5 1 30.6 0 60.7>
Single byte commands
These are single character commands without additional parameters:
o – print single readout
R – turn ON cyclic print (print every second).
r – turn OFF cyclic print
A - switch ON TEC supply
a - switch OFF TEC supply
