5.6.2 Port 2
Group Register Content Description
5040 Enabled This parameter enables the port. Valid entries are 0 and 1.
5041 Baud Rate This is the baud rate to be used on the port. Enter the
baud rate as a value. For example, to select 19K baud,
enter 19200. Valid entries for this field include 110, 150,
300, 600, 1200, 2400, 4800, 9600, 19200, 28800, 38400,
57600, and 115.
5042 Parity This is the parity code to be used for the port. None, Odd,
Even.
5043 Data Bits This parameter sets the number of data bits for each word
used by the protocol. Valid entries are 5 or 8.
5044 Stop Bits This parameter sets the number of stop bits to be used
with each data value set. Valid entries are 1 and 2.
5045 RTS On This parameter sets the number of milliseconds to delay
after RTS is asserted before the data is transmitted. Valid
values are 0 to 65535.
5046 RTS Off This parameter sets the number of milliseconds to delay
after the last byte of data is sent before the RTS modem
signal will be set low. Valid values are 0 to 65535.
5047 Minimum
Response
Time This parameter specifies the minimum number of
milliseconds to delay before responding to a request
message. This pre-send delay is applied before the RTS
on time. This may be required when communicating with
slow devices.
5048 Use CTS
Line This parameter specifies if the CTS modem control line is
to be used. If the parameter is set to 0, the CTS line will
not be monitored. If the parameter is set to 1, the CTS line
will be monitored and must be high before the module will
send data. This parameter is normally only required when
half-duplex modems are used for communication (2-wire).
5049 Slave ID This parameter defines the virtual slave address for the
internal database. Any request received by the port with
this address will be processed by the module. Be certain
each device has a unique address on a network. Valid
range for this parameter is 1 to 255 (247 on some
networks).
5050
Use Guard
Band
Not implemented.
5051 Guard
Band Time Not implemented.
5052 Direct
Control This parameter enables direct control. If enabled, a Select
command is not required before a Control command.
Valid entries are 0 and 1.
5053 Swap
Config This parameter sets data swapping. The swapping is set
as a bit field. Bit 0 corresponds to status data, Bit 1 to
analog data, and Bit 2 to meter data.
