^*c-2Except ST-6200

^*d-4Due to the COM port specifications, flow control is limited, and therefore the wiring diagram may need to be configured differently.
Displays with Limited Support for Control Signals

^*d-5Except PFXST6200AWADI

^*8Only the COM port which can communicate by RS-422/485 (4 wire) can be used.

IPC COM Port

NOTE

Control method when using the RS422 cable is XON/XOFF only. XON/XOFF control is enabled only for ASCII.

Forced:

- Use the twist pair cable with approx. 50pF/m capacitance, 100 Ω characteristic impedance, made of 24AWG rod.

IMPORTANT:

The RS422 cable length is normally 1000m at maximum, but the cable length has the limit depending on the connecting host device. For connection, be sure to refer to the manual of the connecting host device.
The connecting method or termination resistance varies depending on the connecting host device.
Not isolated on the Display side.
Always connect SG between Displays.
When the External Device is isolated, SG connection between the External Device and the Display may not be required.

DANGER

ELECTRIC SHOCK

Ensure that the ground connection for each component of interconnected equipment is reliably connected to the same ground potential (within 100 ohms) prior to connecting the equipment.

Failure to follow these instructions will result in death or serious injury.

WARNING

UNINTENDED EQUIPMENT OPERATION

Use shielded twisted-pair cables.
Connect the cable shields, then connect the cable to a single-point ground on the Display side.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
