the cable?
Thermolator TW-1 and TW-2
Solution
If the Thermolator is not con-
nected to a host device, set the
SPI address to OFF using the
Setpoint adjustment buttons on
the control panel.
❒ 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 net-
work.
❒ Make sure the baud rate
(9600, 4800, 2400, or 1200)
matches the host machine.
Check the communication
cable condition and connec-
tions. The cable must conform
to SPI standards. Check for
loose connections on the
motherboard.
