Serial Port A Settings
When the DeviceNet Interface Unit is used, the PT is connected to the host
through the DeviceNet Interface Unit. That is why the PT cannot communicate
with the host through serial ports A and B. Serial port A can be used only for a bar
code reader and serial port B cannot be used at all.
The NT31/NT31C and NT631/NT631C are equipped with a bar code reader in-
put function that allows character string data to be input from a bar code reader
into character string input fields. This section explains how to set the commu-
nications conditions for communications with the bar code reader and the input
data confirmation method.
Reference 1. When a bar code reader is connected to serial port A, character string data
can be input from a bar code reader into character string input fields. The bar
code reader type, connection method, communications settings, and op-
eration are all the same as they are with standard OMRON system pro-
grams. This manual does not provide details on these subjects. Refer to the
PT’s Setup Manual for details.
2. Either PT memory switches or CompoBus/D setting switches can be se-
lected from the memory switch menu. The PT memory switches are the
same memory switch settings found in the standard system programs. The
CompoBus/D setting switches are the settings for the DeviceNet Interface
Unit.
3. The system menu for the DeviceNet Interface Unit does not contain settings
for serial port B, so the PT memory switch setting requires only 3 screens.
Use the following operations from the system menu to set the communications
conditions for communications with the bar code reader and the input data con-
firmation method.
Press Maintenance Mode.
Press Memory Switch.
