(#8137) - Remote ASYNC Node

#8137 provides remote connection of up to 16 EIA-232 devices to a 128-Port Asynchronous Controller.

Each port can be individually programmed to provide a asynchronous connection of 230 Kbaud, but a limited number of ports in a maximum configuration (128 ports) can be supported at this baud rate.

• Operation of 16 to 128 ports by supporting up to 8 RANs (4 per synchronous line) with either a Micro Channel, ISA or PCI host adapter.
• Ability to monitor individual port operation, synchronous line station, and other diagnostics from front panel.
• Built-in diagnostics can test ports independent of RS/6000 host.
• Full modem control supports the following interface signals: TxD, RxD, RTS, CTS, DSR, DCD, DTR, RI.
• The same RJ-45 to DB-25 Converter Cable (feature #8133 -- quantity four per order) currently used on the existing RANs can be used to attach devices having a DB-25 connector to the Remote Async Nodes.
• Individual ports support a maximum EIA-232 distance of up to 31 meters (100 feet), depending on the baud rate.
• Use of the same cabling from host to RAN and RAN to RAN: feature #8131 (4.5 meter), feature #8132 (23 cm) or customer supplied cables.
• Location of RAN up to 330 meters (sync data rate set at 1.2 Mbps) from host using standard shielded 8-wire twisted pair cabling.
• Remote operation via synchronous modems or CSU/DSU extends the distance and allows location of RANs at geographically distant location from the host.
• Attributes provided: 16 EIA-232 Async ports
• Attributes required: One 128-port adapter per eight (#8137s)
