Connectors and Indicators
J3 - Machine Connector (JMACH1 Port)
The primary machine interface connector is JMACH1, labeled J3 on the PMAC. It contains the pins for
four channels of machine I/O: analog outputs, incremental encoder inputs, amplifier fault and enable
signals and power-supply connections.
1. 50-pin female flat cable connector T&B Ansley P/N 609-5041
2. Standard flat cable stranded 50-wire T&B Ansley P/N 171-50
3. Phoenix varioface module type FLKM 50 (male pins) P/N 22 81 08 9
J4 - Machine Connector (JMACH2 Port)
This machine interface connector is labeled JMACH2 or J4 on the PMAC. It contains the pins for four
channels of machine I/O: end-of-travel input flags, home flag and pulse-and-direction output signals. In
addition, the B_WDO output allows monitoring the state of the Watchdog safety feature.
1. 34-pin female flat cable connector T&B Ansley P/N 609-3441
2. Standard flat cable stranded 34-wire T&B Ansley P/N 171-34
3. Phoenix varioface module type FLKM 34 (male pins) P/N 22 81 06 3
J8 - Serial Port (JRS232 Port)
This connector allows communicating with PMAC from a host computer through a RS-232 port. Delta
Tau provides the Accessory 3L cable that connects the PMAC to a DB-9 connector.
1. 10-pin female flat cable connector T&B Ansley P/N 609-1041
2. Standard flat cable stranded 10-wire T&B Ansley P/N 171-10
TB1 – Power Supply Terminal Block (JPWR Connector)
In almost in all cases the PMAC2A PC/104 will be powered from the PC/104 bus, when it is installed in a
host computer’s bus, or from the JMACH1 connector. This terminal block may be used as an alternative
power supply connector or to easily measure the voltages applied to the board.
1. 4-pin terminal block, 0.150 pitch
LED Indicators
D1: when this red LED is lit, it indicates that the watchdog timer has tripped and shut down the PMAC.
D2: when this green LED is lit, it indicates that power is applied to the +5V input.
