Configuring the Radio to Support Multiple Hosts(Only if operating in Packet mode without MAC)A “host” in a telemetry system refers to the polling application and coordinatesthe routing of data between the master unit site and the remotelocations. Many systems employ only one host computer, and no specialsettings beyond the default menu selections are needed.In some systems, however, multiple host applications (possibly on differentcomputers) may be operating at the master unit site. These computerscan be running completely separate data streams, and yet both canuse the SD Transceiver to communicate their data to and from the dataequipment at associated remote sites. This is accomplished by connectingeach host to one of the data interface ports on the SD transceiver.Multihost configuration is only set at the Master site. Enabling Multihostcauses the radio to allow single poll response transactions in a“round-robin” fashion on each enabled port. The ports can be physicalports like COM1 and COM2 or Payload ports (up to three, using theradio’s one physical LAN connection).The Multihost Settings Menu (Figure 24) is used to view or set the multihostparameters for the radio. This menu may be accessed by the followingnavigation path: Main Menu>>Device Configuration>>Multihost Settings.To make changes in the settings, proceed as follows:1. To enable or disable multihost capability, select Multihost Enable fromthe menu. A flashing cursor appears in the field to the right of theitem.2. Press the spacebar until the desired selection is shown, and pressENTER to apply the change.3. To set/change the multihost delay time, select Multihost Delay fromthe menu. A flashing cursor appears in the field to the right of theitem.4. Enter the desired delay time (in ms) and press ENTER to apply theentry.30 SD Series Serial-Telnet Supplement MDS 05-6193A01, Rev. A
