Signal Descriptions

Table 6-5 Signal Descriptions

Mnemonic Signal

Description

VCC

+5 Volts DC power

+5V STDBY

+5 Volts DC standby power for the real-time clock preservation

GND

The DC voltage reference for the system

+12V

+12 Volts DC power (unused)

-12V

-12 Volts DC power (unused)

BG0IN~ to BG3IN~,

BG0OUT~ to BG3OUT~,

IACKIN~, IACKOUT~

The VITA VME64 and VME64x standards define these signals as daisy chain signals. As such, they are connected together

(OUT to IN) to allow the daisy chain to continue without affecting the values in any way

SYSRESET~

When active (low), this causes a hardware reset of the board

GPn(0)/GPn~(0)

Gigabit Ethernet Port n Pair 0. 100

matched pair

GPn(1)/GPn~(1)

Gigabit Ethernet Port n Pair 1. 100

matched pair

GPn(2)/GPn~(2)

Gigabit Ethernet Port n Pair 2. 100

matched pair

GPn(3)/GPn~(3)

Gigabit Ethernet Port n Pair 3. 100

matched pair

MNG_TX, MNG_TX~,

MNG_RX, MNG_RX~

Service 10/100BaseT Ethernet Port transmit and receive 100

differential signal pairs. The software uses these for

management/control. The Tx and Rx pairs are routed over the shortest distance to an RJ-45 jack (the magnetics are on the

main board)

COM1_TXD, COM1_RXD

2-wire (transmit and receive) serial communications port 1 from a DUART.

The DUART is only used by the software

COM2_TXD, COM2_RXD

2-wire (transmit and receive) serial communications port 2 from a DUART.

The DUART is only used by the software

BIT_PASS

Open collector output used to indicate BIT Pass/Fail status (high = BIT Pass, low = BIT Fail or in progress.

Able to sink 50 mA up to 5V

BP_SOFT_KILL

A voltage between 5V and 12V applied to this pin disables all power supply generation on board

BP_FSTART~

Hardware Fast Start active low enable pin to force the GBX24 to start quickly

BP_RECOVER~

Flash recovery mode. Forces the board to boot-up from the reserve bank of Flash

BP_NED_EVENT

Nuclear event detected input. This is an active high signal, and is normally grounded. A voltage between 5V and 12V

applied to this pin will cause the on board power rails to be crowbarred immediately

Reserved

Reserved by the VITA VME64 and VME64x standards

a. Non-standard option.

NOTE

The GBX24 will not disrupt, in any way, the VME-defined signals in a standard VME backplane. These

signals are not connected internally on the GBX24.

Ethernet ports GP9, GP11, GP15 and GP17 are disabled when the front panel optics are fitted.
