Parameters

Communications (P772)

The SITRANS LU01 communication ports are configured by a series of parameters that are indexed by port.

Communication parameters are indexed to these communication ports, unless otherwise noted:

Port	Description

1RS-232 port (RJ-11 modular telephone)

2RS 485 port on terminal block

P772 Baud Rate

The communication rate with the master device.

Primary Index	Communications Port

	4.8	*	4800 baud

Values	9.6		9600 baud

	19.2		19,200 baud
	19.2		19,200 baud

	115.2		115,200 baud

This specifies the rate of communication in baud. Any value may be entered but only the values shown above are supported. The baud rate should reflect the speed of the connected hardware and protocol used.

SmartLinx Hardware Testing

These parameters are used to test and debug a SmartLinx card (if installed).

P790 Hardware Error

The results of ongoing hardware tests in the communications circuitry.

		PASS		*	No errors
	Values
	Values	FAIL			faulty SmartLinx module or SITRANS LU01

		ERR1			unknown protocol; upgrade the LU01 software

	Related	•	P791 Bus Error
	Related	•	P792 Bus Error Count
		•	P792 Bus Error Count

If any test does not meet the PASS requirements, communication halts and tests are repeated until PASS requirements are met. Communication then resumes. If FAIL or ERR1 is displayed in P790 (Hardware Error), go to P791 (Bus Error) for information about the error.
