UDS1100 User Guide 28
Channel 1
Disable Serial Port When selected, disables communication through the serial
port. The serial port is enabled by default.
Note: This feature is not available on single port device
servers.
Port Settings
Protocol From the drop-down menu, select the protocol type for the
selected channel. The default setting is RS232.
Flow Control Flow control manages data flow between devices in a network
to ensure it is processed efficiently. Too much data arriving
before a device is prepared to manage it causes lost or
retransmitted data. None is the default.
Baud Rate The unit and attached serial device, such as a modem, must
agree on a speed or baud rate to use for the serial connection.
Valid baud rates are 300, 600, 1200, 2400, 4800, 9600
(default), 19200, 38400, 57600, 115200, and 230400 baud.
The default setting is 9600.
Data Bits Indicates the number of bits in a transmitted data package.
The default setting is 8.
Parity
Checks for the parity bit. The default setting is None.
Stop Bits The stop bit follows the data and parity bits in serial
communication. It indicates the end of transmission. The
default setting is 1.
Pack Control
Enable Packing Select to enable packing on the UDS1100.
Two firmware-selectable packing algorithms define how and
when packets are sent to the network.
The standard algorithm is optimized for applications in which
the unit is used in a local environment, allowing for very small
delays for single characters, while keeping the packet count
low.
The alternate packing algorithm minimizes the packet count
on the network and is especially useful in applications in a
routed Wide Area Network (WAN). Adjusting parameters in
this mode can economize the network data stream.
Disabled by default.
Idle Gap Time Select the maximum time for inactivity. The default time is
12 milliseconds.
Match 2 Byte Sequence Use to indicate the end of a series of data to be sent as one
group. The sequence must occur sequentially to indicate end
of the data collection to the UDS1100. The default setting is
No.
