SPI Communication
Possible cause
Solution
Is the unit connected to a
host machine?
If the Thermolator is not connected to a host device, set the
SPI address to OFF using the
Setpoint adjustment buttons on
the control panel.
Are the network address
and baud rate correct?
❒ Check the network address.
The address may be set to
any number from 32 to 254
(a hexadecimal integer
between 20 and FE), as long
as that number has not been
assigned to another machine
connected to the same network.
❒ Make sure the baud rate
(9600, 4800, 2400, or 1200)
matches the host machine.
Is something wrong with
the cable?
Check the communication
cable condition and connections. The cable must conform
to SPI standards. Check for
loose connections on the
motherboard.
The SPI communication link has failed.
