Support Information

All front panel connectors have metal shells and jack posts that are electrically connected to the front panel. If the front panel is electrically connected to the chassis ground, then the shells and jack posts are connected to chassis ground. This allows shielded cable to be used for effective reduction of EMI and EMC problems.

Connector P2 Interconnect Signals (LCP2 Adapter)

Connector P2 on the LCP2 adapter board is a standard DIN 41612 triple-row, 96-pin male connector. Each pin connection, signal mnemonic, and signal characteristic for the connector rows A and C are the same pin-for-pin as connector P2 on the MVME1xx VMEmodule. Row B has only +5 Vdc and ground connected on the LCP2 adapter.

Connectors J1, J3-J5 Interconnect Signals (MVME712x)

Connectors J1 and J3-J5 are EIA-232D 9-pin front panel connectors. Each pin connection, signal mnemonic, and signal characteristic for the connectors is listed in Table 3-3.

.

Table 3-3. Connectors J1, J3-J5 Interconnect Signals (MVME712x)

	Pin	Signal	Signal Name and Description
	Number	Mnemonic	Signal Name and Description
	Number	Mnemonic


	1	DCD	DATA CARRIER DETECT - Sent by the modem
			to the terminal to indicate that a valid carrier is
			being received. Not used by port 1 (J1).

	2	RXD	RECEIVE DATA - data that is demodulated
			from the receive line is presented to the terminal
			by the modem.

	3	TXD	TRANSMIT DATA - data to be transmitted is
			furnished on this line to the modem from the
			terminal.

	4	DTR	DATA TERMINAL READY - A signal from the
			terminal to the modem indicating that the
			terminal is ready to send or receive data.

	5	GND	GROUND

	6	DSR	DATA SET READY - DSR is a function supplied
			by the modem to the terminal to indicate that
			the modem is ready to transmit data. This signal
			can be held high or low through header J8, J9,
			J13, J14.
