ACC-2P HARDWARE SETUP

On the Acc-2P, there are many jumpers (pairs of metal prongs), called E-points. Some have been shorted together; others have been left open. These jumpers customize the hardware features of the Acc-2P for a given application and must be setup appropriately. The following is an overview of the several jumpers grouped in appropriate categories. For a complete description of the jumper setup configuration, refer to the Acc-2P E-Point Descriptions chapter.

I/O Configuration Jumpers

E3-E4: JHW, PD Function Select – When jumper E3 connects pins 2 and 3, a set of pulse and direction signals can be output on channel 1 (pins 2 to 5) of the JHW, PD port. If E3 connects pins 1 and 2, then channel 1 is configured as a handwheel encoder input. When jumper E4 connects pins 2 and 3, a set of pulse and direction signals can be output on channel 2 (pins 6 to 9) of the JHW, PD port. If E4 connects pins 1 and 2, then channel 2 is configured as a handwheel encoder input.

E5: I/O Gate address select – If jumper E5 connects pins 1 and 2 the I/O features on the Acc-2P will be accessed at the regular addresses and the JTHW port can be used as a multiplexer port. When E5 connects pins 2 and 3 the I/O features on the Acc-2P board will be accessed at the regular addresses plus $40, and this is necessary only when both Acc-2P and Acc-1P are used with the same PMAC2A PC/104 baseboard.

E7-E10: Ports Direction Control – These jumpers select the I/O lines direction of the JTHW and the JOPT connectors. This allows configuring these ports as all inputs, all outputs or half inputs and half outputs according to the following tables:

If E7 is removed or E8 is installed then the multiplexing feature if the JTHW port cannot be used.

Communication Jumpers

E1: USB/Ethernet Micro Controller Firmware reload enable – This jumper was added on revision – 103 and above of the Acc-2P. Factory default position is ON, and it should remain ON. If the firmware was corrupted due to a previous firmware download, the card firmware may be reloaded by powering on the card with the jumper off, installing the jumper without powering off, then downloading firmware with out powering off. Under normal circumstances, this jumper should be on even when upgrading firmware.

E6: Communications Port Selection – When jumper E6 connects pins 1 and 2 the PC/104 communications port is enabled. If E6 connects pins 2 and 3 the Ethernet or USB ports are enabled. Only one port can be used at a time. If either the Ethernet or USB ports are used then jumper E19 on the base board must be installed and jumper E18 on the base board must be removed. In order to communicate through the RS-232 serial port jumper E6 must be installed, either in position 1-2 or 2-3.
