Stop Bits Setting
This parameter determines the number of stop bits that the OIT uses to communicate to
the host controller. Options are 1 Bit or 2 Bits. When the OIT is in Configuration mode,
one stop bit is used to communicate to STEPware-100 regardless of how this setting has
been configured.
Factory Default: 1 Bit
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT - Host Serial Communications Settings group box, select the desired number
of stop bits from the Stop Bits option buttons.
To modify this parameter in Configuration mode:
1. At Stop Bits:, use the OIT’s Period (.) key to select the desired number of stop bits.
Refer to the Configuration Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. Use the Set Communications Parameters control command. Refer to Appendix A:
Control Commands for more information.
Handshaking Setting
This parameter determines the type of handshaking that is used between the OIT and the
host controller. Handshaking allows the host controller to regulate when the OIT sends
information; preventing the OIT from overwriting the host controller’s serial buffer or vice
versa. Options are software handshaking (XON/XOff), hardware handshaking (RTS/CTS),
both, or none. When the OIT is in Configuration mode, no handshaking is used to
communicate to STEPware-100 regardless of how this setting has been configured.
Factory Default: No Handshaking
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT - Host Serial Communications Settings group box, select the desired
handshaking in the Handshaking list box.
To modify this parameter in Configuration mode:
1. At Handshake:, use the OIT’s Period (.) key to select the desired handshaking. Refer
to the Configuration Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. Use the Enable Handshaking control command. Refer to Appendix A: Control
Commands for more information.
