SECTION 3
Preparations for Communications
Host Communications Check Mode
Host Communications Check Mode can be used to check if data sent from the ID Controller is reaching
the external device. In this mode, a response is sent to the host device from the ID Controller, making it
easier to identify communications setting or wiring errors that cause faults in connections between ID
Controllers and host devices.
1.
Set pins 3 to 8 on DIP switch SW3 to the desired communica-
tions settings and turn ON the power.

2.
Turn OFF the mode switch (SW5) if it is ON.
3.
Set rotary switch SW1 to 8.
4.
Turn ON the mode switch (SW5).
Response frames will be sent to the host device in the following order:
1. A response frame is sent from the RS-232C port
2. A response frame is sent from the RS-422/RS-485 port.
3. A response frame is sent from the USB port.
These three steps will be repeated each time the mode switch (SW5)
is turned ON until rotary switch SW1 is returned to its normal setting.
Always return the rotary switch (SW1) to its normal setting after completing checking communications with the host
device.
