Perle Systems 5500161-40 Default Full, Default Auto Flow Control, Enable Inbound, Monitor DCD

Serial Port Profiles

Duplex	Used with a EIA-485serial interface, specify whether the serial port is Full
	Duplex (communication both ways at the same time) or Half Duplex
	(communication in one direction at a time).
	Default: Full

TX Driver Control Used with a EIA-485serial interface, if your application supports RTS (Request To Send), select this option. Otherwise, select Auto.

Default: Auto

Flow Control	Defines whether the data flow is handled by the software (Soft), hardware
	(Hard), Both, or None. If you are using SLIP, set to Hard only. If you are
	using PPP, set to either Soft or Hard (Hard is recommended). If you select
	Soft with PPP, you must set the ACCM parameter when you configure PPP for
	the Serial Port.
	Data Options: Soft, Hard, Both, None
	Default: None
Enable Inbound	Determines if input flow control is to be used.
Flow Control	Default: Enabled
Enable Outbound	Determines if output flow control is to be used.
Flow Control	Default: Enabled
Monitor DSR	Specifies whether the EIA-232 signal DSR (Data Set Ready) should be
	monitored. This is used with modems or any device that sends a DSR signal.
	When it is monitored and the IOLAN detects a DSR signal, the serial port
	profile is started. The Monitor DSR parameter is not available for medical unit
	models. If both Monitor DCD and Monitor DSR are enabled, both signals must
	be detected before the serial port profile is started.
	Default: Disabled
Monitor DCD	Specifies whether the EIA-232 signal DCD (Data Carrier Detect) should be
	monitored. This is used with modems or any other device that sends a DCD
	signal. When it is monitored and the IOLAN detects a DCD signal, the serial
	port profile is started. If both Monitor DCD and Monitor DSR are enabled, both
	signals must be detected before the serial port profile is started.
	Default: Disabled
Enable Echo	This parameter applies only to EIA-485 Half Duplex mode. All characters will
Suppression	be echoed to the user and transmitted across the serial ports. Some EIA-485
	applications require local echo to be enabled in order to monitor the loopback
	data to determine that line contention has occurred. If your application cannot
	handle loopback data, echo suppression should be enabled.
	Default: Disabled
Enable Line	Used with EIA-422and EIA-485on SDS 8-port and 16-port rack mount
Termination	IOLAN models, specifies whether or not the line is terminated; use this option
	when the serial port is connected to a device at the end of the serial network.
	Default: Disabled
