PMAC2A PC104 Hardware Reference Manual

Option 12: Analog-to-Digital Converters

Option 12 permits the installation of two channels of on-board analog-to-digital converters with ±10V input range and 12-bits resolution. The key component installed with this option is U20.

Acc-1P: Axis Expansion Piggyback Board

Acc-1P provides four additional channels axis interface circuitry for a total of eight servo channels, each including:

•12-bit ±10V analog output

•Pulse-and-direction digital outputs

•3-channel differential/single-ended encoder input

•Four input flags, two output flags

•Three PWM top-and-bottom pairs (unbuffered)

Acc-1P Option 1: I/O Ports

Option 1 provides the following ports on the Acc-1P axes expansion board for digital I/O connections.

•Multiplexer Port: This connector provides eight input lines and eight output lines at TTL levels. When using the PMAC Acc-34x type boards these lines allow multiplexing large numbers of inputs and outputs on the port. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any combination.

•I/O Port: This port provides eight general-purpose digital inputs and eight general-purpose digital outputs at 5 to 24Vdc levels. This 34-pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O modules when different voltage levels or opto-isolation to the PMAC2A PC/104 is necessary.

•Handwheel port: this port provides two extra channels, each jumper selectable between encoder input or pulse output.

Acc-1P Option 2: Analog-to-Digital

Converters

Option 2 permits the installation on the Acc-1P of two channels of analog-to-digital converters with ±10V input range and 12-bits resolution. The key component installed with this option is U20.
