  • Page 67: Synchronous Interfaces

    Hardware Reference Asynchronous interfaces follow the RS-232 standard. A range of speeds is selectable using the SET PORT command from the Interfaces chapter of your router’s Software Reference. Not all signals need to be connected. In particular, both DCD and CTS are not required unless the interface has been specifically set up to use them.

  • Page 68: Ethernet Interfaces

    AR Router data, while asynchronous modems don’t require a clock and rely on the inherent framing provided by the start and stop bits. Normally, any modem 9600 bps or faster will be synchronous. The router can be connected to other remote routers to form a wide area network (WAN), using synchronous modems connected to the synchronous interfaces on the router’s rear panel.

  • Page 71 Hardware Reference AR routers support a wide range of interface types, including Ethernet, asynchronous, synchronous, Basic Rate ISDN and Primary Rate ISDN. Each interface type (except Ethernet interfaces on the AT-AR026 PIC) can be tested independently using the Test Facility software. Most tests, however, will also require the use of a loopback plug.

  • Page 72: Asynchronous Interface Tests

    AR Router Asynchronous Interface Tests Asynchronous interfaces require a loopback plug to be installed before the test will operate. See “Cables And Loopback Plugs” on page 73 for details of how to make a loopback plug. To start a test of an asynchronous interface, use the command: ENABLE TEST INT=PORT n where n is the interface number.

    Hardware Reference Cables And Loopback Plugs This section describes how to make cables for connecting the AR router to networks, terminals, and printers. It also describes loopback plugs, which are required for testing most AR router interfaces. Transition Cables for Network Interfaces AR router synchronous ports use AMPLIMITE 50-way connectors wired as universal connectors to supp/rt RS-232/V.28, V.35 and X.21 interface standards.
  • Page 74 AR Router It is very important that the cables do not degrade EMC emission standards of the router (e.g., FCC, CISPR). The cable foil shield must be connected to the AMPLIMITE metalised backshell with a 360 degree ferrule. In addition, on specified cables, a clip-on cable ferrite must be attached to the cable at the AMPLIMITE end, no more than 25 mm from the rear of the backshell of the AMPLIMITE connector.

    AR Router Installing a Flash SIMM Early models of AT-AR720 routers can be upgraded from the factory default 4MB of flash memory to 8MB of flash memory by installing a 4MB 80-way Single Inline Memory Module (SIMM) stick. SIMMs should only be installed by authorised service personnel. Unauthorised opening of the router lid may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty.

    AR Router Replacing Boot EPROMs AR300 Series routers have one boot EPROM and AR720/AR740 routers have two boot EPROMs. Boot EPROMs contain bootstrap code, which loads the main code from a software release file in flash memory. In rare circumstances the boot EPROM(s) may need to be changed.
  • Page 109 Hardware Reference router base CPU board. Remove the boot EPROMs using the extraction tool. Alternatively, a small flat-bladed screwdriver can be used. If so, gently lever each end of a particular boot EPROM a few millimetres at a time until it comes free. Table 41: Diagrams showing the locations of EPROMs for each router model.
