5.4.10.4 USB Port
The PT6X0 instruments have a standard USB serial port. You can connect a PC or device temporarily
(with the case open) using a standard USB mini-B cable or permanently through a sealing gland with a
PT cable A-CAB-SER-USB .
The USB port is a standard USB port that does not need drivers for serial communications. Your PC
should be able to access this with standard serial communications software or commands.
Enter configuration (6.2.4) to access parameter blocks to make the settings below.
Set data format or mode from no data transfer, continuous data output, Fast continuous mode.
Set checksum, carriage return, line feed and response speed.
5.4.10.5 Ethernet Port
Not available on the PT620
The Ethernet port, if provided on board or with an option card, is available for serial communications.
Enter configuration (6.2.5) to access parameter blocks to make the settings below.
Set data format or mode from no data transfer, continuous data output, print mode, BSI command
mode, Modbus RTU High-Low, Modbus RTU Low-High, Fast continuous mode.
Set IP address, device address, sub-mask address, gateway address, local port number(s), DNS
address, MAC address, idle timeout, CR-LF option, remote IP address and remote port number.
Contact you local network administrator if you require information regarding these settings.
Info: Using the remote IP address and remote port number you can print to a remote network attached
printer or device.
5.4.10.6 Continuous Data Formats
Continuous data output from the instrument is transmitted in the following data structures. There are 2
options for continuous output. Continuous output and fast continuous output.
Note: CR (Carriage return) and LF (Line feed) codes can be enabled or disabled from the response in
interface port settings
[11-] , 6.2.1 [15-] 6.2.5 but they must be sent to the PT6X0 series at the end of
ASCII commands, I.e in BSI communication.
Continuous Data Format
Continuous data output is transmitted in the following data structure. The serial ports are suitable for bi-
directional communication. If, you transmit ASCII codes for the P(print), Z(zero), T(tare) or C(clear)
letters to the serial port the indicator will act as if the related keys had been pressed.
CHK (Checksum) can be enabled or disabled from both command and response and only continuous
data output can be programmed for more than one interface.

Status C (STC) is always hex ‘30’.
CHK (Checksum) = 0 – (STX+STATUS A+...+LF)
Note: The weight data is represented right aligned and the following error messages (UNDER, OVER,
L-VOLT, H-VOLT and A.OUT) are represented left aligned in the Displayed Weight field.
Fast Continuous Data Format
Fast continuous “indicated weight” data output can be used only for receiving instruments that can
communicate fast. There is no flow control if the device cannot keep up with the data flow. The output
