PMAC2A PC104 Hardware Reference Manual

For this driver, the internal resistor packs pull-down instead. With a UDN2981A driver IC, Jumper E1 must connect pins 2 and 3, and Jumper E2 must connect pins 2 and 3.

Example: Standard configuration using the ULN2803A sinking (open-collector) output IC.

Further software settings are required to configure this port. See the Software Setup section for details.

Acc-2P General-Purpose Digital Inputs and Outputs (JOPT Port)

Acc-2P JOPT connector provides sixteen lines of general-purpose I/O. In contrast with the Acc-1P J7 connector, the lines on the Acc-2P JOPT connector are limited to TTL levels and are usually used with external I/O modules. Each I/O line has its own corresponding ground pin in the opposite row. The 34- pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O modules. Delta Tau’s Acc-21F is a six-foot cable for this purpose.

Jumpers E9 and E10 on the Acc-2P board select the I/O lines direction of the JOPT connector. This allows configuring this port as all inputs, all outputs or half inputs and half outputs. Further software settings are required to configure this port. See the Software Setup section for details on this.

Acc-1P Thumbwheel Multiplexer Port (J2 Port)

The Thumbwheel Multiplexer Port, or Multiplexer Port, on the J2 connector has eight input lines and eight output lines. The output lines can be used to multiplex large numbers of inputs and outputs on the port, and Delta Tau provides accessory boards and software structures (special M-variable definitions) to capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any combination. Either the Acc-1P or the Acc-2P boards, but not both, can use this connector as a multiplexing port. This is selected by jumper E6 on the Acc-1P board and jumper E5 on the Acc-2P board.

Alternatively, the inputs and outputs on this port may be used as discrete, non-multiplexed I/O. In this case, these I/O lines can be accessed through M-variables. See the Software Setup section for details on this.

Acc-2P Thumbwheel Multiplexer Port (JTHW Port)

The Thumbwheel Multiplexer Port, or Multiplexer Port, on the JTHW connector has sixteen lines. These lines can be used to multiplex large numbers of inputs and outputs on the port, and Delta Tau provides accessory boards and software structures (special M-variable definitions) to capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any combination. Either the Acc-1P or the Acc-2P boards, but not both, can use this connector as a multiplexing port. This is selected by jumper E6 on the Acc-1P board and jumper E5 on the Acc-2P board.

Alternatively, the inputs and outputs on this port may be used as discrete, non-multiplexed I/O. In this case, these I/O lines can be accessed through M-variables. See the Software Setup section for details on this.
