2.9 USB Serial Port and SD Card
The USB Serial Port and the SD Port on the front panel
supports connection to a PC or other communications
device. It transfers data in either direction: the MJ-5
Control Panel can provide meter and status information to
an external device, and the control program can be
configured from an external device.
The USB Serial Port supports data transmission at standard
data rates from 300 to 19200 baud, inclusive, using the
2200 communications protocol enhanced with MJ-5 data
fields.
The SD Card Port supports Low Capacity (< 4GB) and
High Capacity (>4GB) SD card which can store the
configuration and use it to configure the entire system at
one time. The SD Card is also used for saving the Logs
and is conducted either manually or periodically at certain
intervals.
The device used for communications must be configured to
match the following Data Port items in the
<
COMMUNICATIONS
> menu.
•
DatPortBaud
•
Data Parity
•
DataPortAddr - If addressing is on, use the Comm Addr
parameter as the Data Port address.
Note: First time users must download a serial port driver
from Siemens.com or by contacting their Siemens
representative.
