Name	Description	Values	Meaning

HA	Comms 1 module config
id	Identity of the module installed	cmS	2-wire EIA-485


For ‘id’ = ‘cms’ (Digital communications) use this parameter table:
Func	Function	mod	Modbus protocol
		mAr	Marathon Monitors protocol
bAud	Baud Rate	1200, 2400, 4800, 9600,
		19.20(19,200)
dELy	Delay - quiet period, required by	no	No delay
	some comms	YES	Delay active - 10mS
	adaptors
Prty	Comms Parity	nonE	No parity
		EvEn	Even parity
		Odd	Odd parity
The following parameters only appear if the function chosen is Modbus protocol.

rES	Comms Resolution	FuLL	Full resolution
		Int	Integer resolution
