from 256K bytes up to IM byte.

Through the use of easily generated ¹ escape sequences, any port may be routed to any other port. In this modę . it can allow computers to talk to each l other, or allow multiple peripherals to 1 be accessed without any physical switch- • ing or re-cabling.

Serial channels opcrate fully bidirec-tionally and parallel channels can be configured in either direction by means of DIP switch settings. The serial channels will run at speeds up to 38.4k baud and all paths established through the unit are simultaneously buffered.

proof to BS3042 to give maximum pro-tection against electric shock from the front. The fuse carrier is screwdriver-slotted for easy withdrawal.

Silver-plated brass terminations can be soldered or well accepted standard 2.8mm push-on connectors. The standard configuration for the live terminal is “in linę’* but can be supplied as radial.

Buffered interface

An advanccd new buffered interface system, the A2(XX), has been announced [    by Alfatron. Primarily aimed at the PC

market, is said to provide an answer to many problems experienced by users of Computer Systems in office environ-ments.

Designed and manufactured in Australia, the buffer can provide up to six serial and two parallel channels to inter-connect computers and peripherals. Its simplest implementation is as a printer sharer unit, and it offers buffer sizes

Intelligent data    ¹

switches    \

NetCommander is a rangę of inexpen-    s

sive, intelligent data switches, now available from Data Bridge Electronic Communications. One of the switches allows a group of PC users to share one or morę printers and up to 30 devices can be madę to communicate simulta-    J

neously.

The switch continually monitors the serial output port of each PC. When it detects activity, it automatically routes the data to the location speciFied in the i Jeading bits of the transmission.    '

The switch can also be connected to a „i LAN (local area network) node, provid-    i

ing the fuli resources of the LAN to any I device linked to it.    '

The wiring medium can be RS-232C cable or twisted pair wirc and transmission speeds rangę from 300bps up to 19.2kbps.    ;

Multiple protocols and data transmission speeds are handled by the Netcom-mander which has a hardware buffer of up to 1Mb.
