Optomux
Up to 32 Optomux stations configured for multidrop can be used on a serial network of up to 1524 m (5000 ft.) total length. Up to 256 Optomux stations and longer line lengths can be used by installing network repeaters.
Up to 256 Optomux stations configured for repeat mode can exist on a network.

Optomux I/O Functions

Digital I/O (E1): Read Point, Write Point, Latch Point (On/Off), Count, Pulse Duration, Time Delay, Pulse Generation, Watchdog Timer
Analog I/O (E2): Read Point, Write Point, Input Averaging, Min/Max Recording (peak and valley), High/Low Range Testing, Offset and Gain Calculation, Waveform Generation, Watchdog Timer

Modbus/TCP, OptoMMP, and OPC I/O Functions

With these protocols, the following brain-based features are not available:
• No pulsing or time delay (E1)
• No input averaging or waveform generation (E2)

LED Indicators

Status, Link, Activity, Full duplex, Transmit (serial), Receive (serial)

Jumper-selectable Serial Options

Group A: Multidrop or repeat mode, RS-485 termination and biasing
Group B: Serial address (0 to 255), baud rate, 2- or 4-pass protocol

* ±15 VDC ±0.25 V is required for the analog modules. Current depends on the number and types of modules installed. A 24 VDC power supply is required for analog modules that need a current loop source.
