MuxMaster

Distributed Port Concentration
MuxMaster® distributed system of work area port concentrators is the most practical solution to connecting large numbers of terminals, modems and printers in the open systems multiuser environment. Capable of distributing concentrators over a distance of 1000 feet on standard telco wire (typically already installed) without the use of repeaters eliminates new costly wiring plants.
Eliminate data input errors caused by lazy echo response when trying to enter data on ethernet terminal systems on busy networks. Using short packet SDLC packets and a highly efficient "fairness" algorithm, async echo response times are 50 times faster than other distributed methods, such as ethernet terminal servers.
Add to these features the "fault tolerant" nature of the system that allows "on-line" replacement of modules without software intervention and without disturbing other users. A single twisted pair wire connects up to 128 serial ports to a variety of host and network adapters. Compatibility with the EASYway line of network products extends the capability of MuxMaster beyond that of ANY similar product in the industry. See some example sites in the Application Notes.
MuxMaster Port Concentrators
|

16 port work area concentrator supporting full modem (less RING) on RJ45 connectors. Supports port speeds to 115Kbaud with localized flow control and a unit aggregate of 20Kbytes/sec. Under $100 per port. |
|
DS016 |
16 port distributed server supporting full modem (including RING) on DB25 or MMJ connectors. Speeds to 38.4Kbaud per port and a unit aggregate of 20Kbytes/sec. This unit is designed to operate in non-office severe environments. |
|
CS128 |
This Rack mount port concentrator unit supports up to 128 ports in a single 17" rack with "hot swap" replacement of port modules. Redundant Power supplies available |
|
CS016 |
16 port concentrator module for the CS128 rack unit. Module specifications the same as DS016 |
Host & Node Adapters
|
SC04M |
SCSImaster TM adapter allows for up 128 MuxMaster ports and one parallel port to connect to a single SCSI ID. Up to 896 serial ports (7- SC04Ms) can be connected to a single SCSI bus. |
|
PL550 |
Software compatible to a DECserver 550 , the PL550 supports 128 MuxMaster ports; allowing for TWICE the number that DEC can support with full modem control. Desktop or shelf mounted unit is only 4 inches high. |
|
FP105 |
Software compatible and equivalent to 16 DEC DHV or CXY08 modules supporting 128 MuxMaster ports. A single quad width Q-bus board taking 1 slot NOT 16. |
|
FP106 |
Software compatible and equivalent to 8 DEC CXA16 modules with full modem using 128 MuxMaster ports. A single quad width Q-bus board taking 1 slot NOT 8 and NOT just "data only". |
|
FP110 |
Software compatible and equivalent to 8 DEC DHU-11 modules with full modem using 128 MuxMaster ports. A single hex width Unibus board taking 1 slot NOT 8. |
