PMAC Product Guide E28: Following Error/Watchdog Timer Signal Control Default Configuration E28 2-3 1. Jump pin 1 to 2 to allow warning following error (Ix12) for the selected coordinate system to control FEFCO/ on J8-57. 2. Jump pin 2 to 3 to cause watchdog timer output to control FEFCO/. Low true output in either case. E100: Auxiliary Signals Supply Control Default Configuration E100 1-2 The U54 driver IC controls the AENA and EQU signals on the J8 JEQU connector. If E100 connects pins 1 and 2, U54 will be supplied from the analog A+15V supply which can be isolated from the digital circuitry.
If E100 connects pins 2 and 3, U54 will be supplied from a separate A+V supply brought in on pin 9 of the J8 JEQU connector. This supply can be in the +12V to +24V range and can be kept isolated from the digital and analog circuits. E101-E102: Auxiliary Signals Output Voltage Configure The U54 driver IC controls the AENA and EQU signals on the J8 JEQU connector. With the default sinking output driver IC (ULN2803A or equivalent) in U54 for the J8 JEQU port outputs, these jumpers must connect pins 1 and 2 to supply the IC correctly.
If this IC is replaced with a sourcing output driver IC (UDN2981A or equivalent), these jumpers must be changed to connect pins 2 and 3 to supply the new IC correctly. Warning: The jumper setting must match the type of driver IC, or damage to the IC will result. E109: Display Port Configuration Default Configuration E109 OFF This jumper is related to an advanced feature and should not be changed from default. E110: Expansion Port Configuration Default Configuration E110 1-2 This jumper is related to an advanced feature and should not be changed from default. 20 PMAC Jumper Configuration Default Configuration E1 E2 1-2 1-2
