TCP/IP Network Hub (MicroLok® II and MicroLok® Object Controller Applications) To facilitate the new Internet Protocol connectivity between MicroLok II and/or MicroLok Object Controller (OC) systems, the Network Hub has been developed for use with the new network protocol for serial communications. The Hub supports up to eight MicroLok II and/or OC systems connected to it and provides the media access layer for arbitrating the peer-to-peer network protocol. Additionally, the Hub includes an expansion port whereby another Hub can be attached to provide connectivity for up to 16 MicroLok II and/or OC systems. General Description
The Network Hub connects multiple co-located MicroLok II and/or OC units by creating a Local Area Network (LAN) for communications between those units. This Hub provides electrical isolation between the devices connected to it and utilizes an RS-423 interface (configurable RS-232, RS-485, RS-423). It can be connected to any of the serial ports on a MicroLok II CPU PCB or the TCP/IP-compatible ports on the OC. The Hub functions as a media access layer for connecting multiple units in a single location, and will resolve contention issues when multiple units attempt to transmit at the same time. It supports a maximum of eight local connections and can be connected to a second Hub to include an additional eight ports on the LAN, for a total of 16 MicroLok II and/or OC systems on a single LAN. The Network Hub consists of standard 19” rack mountable unit with a single internal PCB. The unit’s front panel incorporates 20 LEDs that display the request and grant status of each channel, including the expansion port, as well as show received and transmitted data activity. The front panel also includes an illuminated power on-off switch. Serial communication cables are connected to 25pin and 9-pin “D” connectors arrayed on the unit’s back panel. ASTS USA provides several serial connector/cable assemblies expressly for these ports (see Ordering Information). Unit operating power is wired to a single Wago style cage clamp connector also mounted on the back panel.

A removable top cover permit access to the unit’s internal circuit board. This board contains dual-inline-package (DIP) switches that permit customized setting of various communications parameters such as unit Master/Slave designation and perchannel communication modes (e.g. RS-485).
Software The MicroLok II Executive and Application (Development System) software has been upgraded to accommodate network protocol functions. Consult your ASTS USA Account Executive when planning to utilize the these functions so that the proper software versions can be incorporated. Advantages

Supports up to eight MicroLok II and/or OC remote systems. Provides electrical isolation between MicroLok II and/or OC systems. Compatible with all MicroLok II CPU PCB serial ports and OC TCP/IP-compatible ports. Provides media access layer for arbitrating peer protocols. Configurable ports for use with all MicroLok II and OC serial port communications standards. Includes configurable time out settings to ensure single port cannot dominate communications link. Second Hub connection adds eight LAN ports, services up to 16 MicroLok II and/or OC systems on a single LAN.
