Xylem H-5223 - Manual (Page 47)

Z -UTC offset
This option allows the user to specify an +/- offset in minutes from the UTC time obtained
from the GPS receiver.
I - Site ID
This option allows the user to enter in an eight character label that defines the site. This will
also be used as the filename for the data file when scanning is turned on.
NOTE: Valid site ID names may include letters, numbers, or the underscore. Spaces and
the decimal point are not valid characters for the site ID and should be avoided.
3.9.1 P - Port Setup
The following options only apply to the main serial port. It may be configured to work with
several types of modems or other systems.
--- Serial Port Setup —--
R - Baud Rate: 9600
F - Flow Control: SW
E - Emulation: VT-100
S - Startup Mode: Menu
Enter Option >
R - Baud Rate
This option sets the baud rate for the serial port. The default is 9600 which will be used for
nearly all applications. Other valid baud rates range from 115200 down to 1200.
F - Flow Control
Flow control is used to pace the data through the serial port. It is important not to send data
faster than the receiving system can receive it. There are two types of flow control, software
and hardware flow control.
Software flow control (SW) is also referred to as XON / XOFF. When this is enabled the
receiving system will send a character (XOFF) to the H-5223 instructing it to stop sending
data until the receiving system can catch up. At the point the receiving system is ready it will
send an XON to the H-5223 indicating it is ready for more data. Software flow control is the
default selection.
NOTE: If using XMODEM protocol for data file transfers, software flow control should
not be used as a binary checksum value is calculated for each block of data and
transferred with the data block. If the binary checksum value is the same as an
XOFF command, then the system may stop the data transfer prematurely.
Hardware flow control uses two extra pins on the 9 pin connector. This is ‘Request to Send’
