USB-Serial Conversion Cable
* Use a high-power port for the USB port.
Note: A driver must be installed in the personal computer. Refer to
installation information in the operation manual for the
Conversion Cable.
Communications Specifications
* The baud rate, data bit length, stop bit length, and vertical parity can be in-
dividually set using the Communications Setting Level.

Heater Burnout Alarms and SSR Failure
Alarms
*1. For heater burnout alarms, the heater current will be measured when the
control output is ON, and the output will turn ON if the heater current is
lower than the set value (i.e., heater burnout detection current value).
*2. For SSR failure alarms, the heater current will be measured when the
control output is OFF, and the output will turn ON if the heater current is
higher than the set value (i.e., SSR failure detection current value).
*3. The value is 30 ms for a control period of 0.1 s or 0.2 s.
*4. The value is 35 ms for a control period of 0.1 s or 0.2 s.
