Tab Parameter Selections
General Diagnostic File SLC 5/03 (OS 302 C or higher), 5/04 (OS 401 C or higher) and 5/05 only. Select an unused file
(9
to 255) to store channel status information. You must define a diagnostic file in order to be
able to view channel 0 status. See
See Table 4.3 on page 4-16 for a file description.
Channel 0
System
Baud Rate Select a communication rate that all devices in your system support. Configure all devices in the
system for the same communication rate.
Parity Parity provides additional message packet error detection. To implement even parity checking,
choose Even. To implement no parity checking, choose None.
Stop Bits Match the number of stop bits to the devices with which you are communicating.
Node Address A node address identifies the processor on the DF1 half-duplex link. Each station on a link must
have a unique address. Choose an address between 0
10
and 254
10.
Node address 255
10
is the
broadcast address, and cannot be selected as a station’s individual address.
Control Line This parameter defines the mode in which the driver operates. Choose a method appropriate for
your system’s configuration:
• If you are not using a modem, choose NO HANDSHAKING.
• If the master modem is full duplex, choose FULL-DUPLEX.
• If all the modems in the system are half-duplex, choose HALF-DUPLEX WITHOUT
CONTINUOUS CARRIER.
See page 4-5 for descriptions of control line operation settings.
