DB-9 Female Pinouts

	DB9F	Signal Name [1]		Functional		Notes
	Pin
1		RTC_Clear		Clears and holds the seconds count of the Real Time Clock at	[3], [6]
			00.
	2	RTC_Seconds		Provides the external time base for the Real Time Clock.		[3], [5]
				Internal time base is 1Hz
3		GND		Signal reference for all signals
	4	EXT_REF_CLK		0-20MHz clock input		[2]
5		GND		Signal reference for all signals
	6	TX_TRIGGER_P1		Transmission trigger for port 1		[3], [4], [5]
7		TX_TRIGGER_P2		Transmission trigger for port 2	[3], [4], [5]
	8	TX_TRIGGER_P3		Transmission trigger for port 3		[3], [4], [5]
9		TX_TRIGGER_P4		Transmission trigger for port 4	[3], [4], [5]

[1] All signals are inputs.

[2] Electrical properties for External Reference clock input: +/- (1-10)Vpp AC sine wave

+/- (3.3-10Vpp square wave.

10-20MHz Frequency range. Capacitive coupled input.

Must be referenced to GND pin.

TTL compatible. For example 0-3.3V or 0-5V will work.

[3] Electrical properties:

+/- (3.3- 10)Vpp pulse.

Minimum pulse width is 100ns seconds. Capacitive coupled input.

Must be referenced to GND pin.

TTL compatible. For example 0-3.3V or 0-5V will work.

[4] Used for Asynchronous transmissions. When the mode is enabled, the Blue Heat/Net Sync will transmit exactly one byte of data when the TX_TRIGGER input changes state. These same signals are available on the individual DB25 port connectors.

[5] The input is edge sensitive and can be configured for negative or positive edge sensitivity.

[6] The input is level sensitive and can be configured for 1 or 0 level sensitivity.
