---|---|---|
|
Selects how the serial COM port on the Link150 gateway is utilized (master or slave). NOTE: When you change the mode and click
, the Link150 gateway reboots and
clears the device list configuration. |
NOTE: ION protocol supports only
mode. |
|
Selects how the Link150 gateway serial port is physically wired. |
|
|
Selects how data is transmitted over a serial connection. |
NOTE: Modbus Automatic mode allows you to communicate
to Modbus RTU, Jbus, and PowerLogic™ (SY/MAX)
slave devices on the same daisy chain.
|
|
Used to select the data transmission speed over a serial connection. |
|
|
Used to select if data is checked for accuracy using a parity bit. |
|
|
Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to re synchronize with the character stream. |
NOTE:
sets stop bit as 1 when you set to or and as 2 when you set to . |
* is set to or . |
Used to terminate the RS485 line in order to prevent reflections. Setting to Enabled enables the termination resistor. |
|
* is set to or . |
Used to prevent invalid data bits by forcing the transmission line into a known state. The transmission line into the RS-485 port enters an indeterminate state when it is not being transmitted to. This indeterminate state causes the receivers to receive invalid data bits from the noise picked up on the cable. |
|
Used to select how long the Link150 gateway waits to receive a response from a serial device. NOTE: The
parameter is disabled if the is set to Slave. |
|
|
(in slave mode only) |
Used to define a list of Modbus TCP/IP addresses for the Link150 gateway to use during slave mode communications. |
- |
(in slave mode only) |
Used to select the Modbus TCP/IP port of the remote device connection. |
