GLOBESERVER SWITCH SETTINGS

Each GlobeServer connected to the TwinSync card must have a unique address. Each line supports four addresses. Line P1 supports GlobeServer addresses 1, 3, 5, and 7 while line P2 supports GlobeServer addresses 2, 4, 6, and 8. ("P1" and "P2" is marked on the TwinSync card endplate).

Switch bits 1,2 and 3 of the DIL switch on the top surface of the GlobeServer unit are used for selecting GlobeServer Address.

The GlobeServer may be connected to the TwinSync card using one of four different interfaces.

• RS485 MultiDrop For local connections up to 1200 Metres. Two wire connection. Line speeds from 250Kbps to 1Mbps. Four GlobeServer units may be connected to one line. (STANDARD MODE) 
• RS422 Point to Point For Leased line X21 type interface (Kilostream synchronous 64Kbps). A maximum of two GlobeServer units per line may be used, supporting 16 ports at a remote location. On an ISDN circuit only ONE GlobeServer may be used per line, supporting 8 ports plus a parallel* port at a remote location. 
• RS232S Point to Point For Leased or dial up line using V34 or faster Synchronous modems. (14K4..28K8bps). Only one GlobeServer unit may be attached - supporting 8 ports plus a parallel* port at a remote location.
• RS232A Point to Point For Leased or dial up line using Async modems capable of supporting 38K4..57K6bps connection speeds. Only one GlobeServer unit may be attached - supporting 8 ports plus a parallel* port at a remote location.

            (*Parallel Printer support is dependent upon the Operating System driver support.)

The GlobeServer system will also support a GlobeServer unit in distant locations (greater than 1200 Metres via leased lines or dial up modems. NOTE other than Kilostream circuits, a line configured to operate over a leased line or modem may only have one GlobeServer unit attached to that line.

Each of the two TwinSync lines may be configured independently. It is possible to configure line P1 for RS485 - 1Mbps operation with one or more GlobeServer units attached while line P2 is configured for RS232 ASYNC use via a dial up modem with one GlobeServer unit attached at the remote end.

Switch bits 4,5 and 6 on the base surface of theGlobeServer unit are used for selecting Line Mode.

NOTE If the GlobeServer is to be used for an X21 connection (RS422 Synchronous - Kilostream or ISDN) then the user should check that the TwinSync card jumpers are set correctly.

When a line is configured for RS485 Multidrop operation the GlobeServer attached to end of the line must have its line termination circuit enabled. The other GlobeServer units on the line must have their termination circuitry disabled.
