Delayed Linefeed Setting
This parameter determines whether the OIT executes an LF control code (hexadecimal
0A) immediately or when the next character is received. If enabled, the OIT does not
execute an LF control code received from the host controller until the next character is
received. If disabled, the OIT immediately executes the LF control code. This parameter
is used most often with host controllers that automatically append an LF control code to
each data transmission.
Factory Default: Disabled
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT Operational Settings group box, select the Delayed LineFeed Enabled check
box.
To modify this parameter in Configuration mode:
1. At Delayed LF:, use the OIT’s Period (.) key to enable or disable delayed linefeed.
Refer to the Configuration Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. Use the Display and Cursor Format control command. Refer to Appendix A: Control
Commands for more information.
Use 3-Wire RS-485 Setting
This parameter determines whether the OIT disables the RS-485 receiver when the OIT
transmits data to the host controller. If the OIT is wired to the host controller using 3-wire
RS-485 half duplex communications, then this option must be enabled for the OIT to
operate properly. Conversely, if the OIT is wired to the host controller using 5-wire RS-485
full duplex communications, this setting must be disabled to allow the host controller to
send a command to the OIT while waiting for a response from a prior command.
Factory Default: Disabled
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT Operational Settings group box, select the Use 3-Wire RS-485 check box.
To modify this parameter in Configuration mode:
1. At RS485 3 Wire:, use the OIT’s Period (.) key to enable or disable 3-Wire RS-485.
Refer to the Configuration Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. This feature cannot be changed from the host controller.
