Features
System performance and throughput are increased by allowing the Optomux I/O unit to do as
much processing as possible, thereby reducing serial line activity and host computer processing.
The following summary of Optomux capabilities will help you determine which tasks can performed
by the B1 or B2 I/O unit.
Digital Optomux
In addition to ON/OFF control, B1 Optomux units provide:
Latched Inputs
Any or all input positions can be used to record momentary events by functioning as latches. Each
input position can be configured by host command to latch on either OFF-to-ON or ON-to-OFF
transitions. The host computer can recall and/or clear the status of these latches.
Time Delays
Any or all output positions can function in time delay mode. Outputs can be set to operate with four
types of delays.
• Delay before turning OFF
• Delay before turning ON
• Pulse ON
• Pulse OFF
Time delays are programmable with a resolution of 10 milliseconds.
