6.1.1 Configuration Values

The module must be configured properly in order to use the pass-through mode.

Port 0 must be configured as a DF1 master port using the full-duplex protocol.

The termination type (BCC or CRC) set on Port 0 is used for the pass-through

port. The module's configuration file must contain the [Pass-Through Port]

section with the Enabled parameter set to "Yes".

Description

[Pass-Through
Port]

Start header for DF1 pass-through port definition.

Enabled:

Yes or No This parameter specifies if the pass-through port is to be utilized

in the application. Additionally, Port 0 must be configured
correctly. Set the parameter to Yes to enable the feature and No

to disable feature.

Local Station ID:

0 to 255

This parameter specifies the local station ID for all DF1 messages

sent to this port. A value of 255 will cause the slave address to be

ignored and the address issued in the master request packet to
use as the slave ID. The application will only accept messages

with this node address.

Protocol:

Full

Duplex or

Half
Duplex

Full duplex, Half-duplex

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.

Parity:

None,

Odd, or
Even

This is the Parity code to be used for the port. The coded values

are as follows: None, Odd, Even.

Data Bits:

7 or 8

This parameter sets the number of data bits for each word used
by the protocol.

Stop Bits:

1 or 2

This parameter sets the number of stop bits for each data value

sent.

RTS On:

0 to 65535 This parameter sets the number of milliseconds to delay after RTS

is asserted before the data will be transmitted.

RTS Off:

0 to 65535 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.

Use CTS Line:

Yes or No This parameter specifies if the CTS modem control line is to be

used. If the parameter is set to N, the CTS line will not be
monitored. If the parameter is set to Yes, the CTS line will be

monitored and must be high before the module will send data.

Normally, this parameter is required when half-duplex modems

are used for communication (2-wire).

Request Timeout: 0 to 65535 This parameter specifies the number of milliseconds to wait for a

complete request message. The timer is started after the DLE-

STX character sequence is received for the full-duplex protocol or

the DLE-SOH sequence for the half-duplex protocol. If the timer

expires, the current request message will be aborted.
