Connect cables to each of these modules following instructions in the <br /> appropriate Installation Manual listed in the table below. <br /> Module Description Manual No. <br /> Required to send designated reports to a remote fax <br /> SiteFax Fax/Modem Interface Module machine' 577013-528 <br /> Provides one RS-232 DB-25 connector and one auxiliary <br /> Auxiliary RS-232 Interface Module RS-232 OB-25 connector 577013-528 <br /> RS-232 Interface Module2 Provides one RS-232 DB-25 connector 577013-528 <br /> Remote Display Interface Module Required with the optional Remote Display 577013-528 <br /> Remote Printer Interface Module Required when communicating to a remote printer 577013-528 <br /> Required only for a TLS-350 with GPU board and an inter- <br /> Printer interface Module nal printer Factory Installed <br /> WPLLD Communication Module Required with Wireless Pressurized Line Leak Detection 577013-481 <br /> 'The SiteFax Fax/Modem Interface Module provides snap-in jacks for direct data <br /> transmission over telephone lines.Connections to telephone lines must meet the <br /> following criteria: <br /> a. Connection to telephone equipment is subject to local regulations. <br /> b. Maximum short circuit current:0 amperes. <br /> c. Maximum open circuit voltage:0 volts. <br /> 2Veeder-Root recommends for a direct connection between the console and a remote <br /> device that you use a null-modem cable not exceeding 50 feet in length.Cable runs <br /> longer than 50 feet can result in data errors,component damage,or both. <br /> If cable runs longer than 50 feet are needed,two short-haul modems should be used, <br /> one at the console and one at the remote device.We recommend an asynchronous <br /> short-haul modem,Black Box model ME800A,or equivalent at the console and at the <br /> remote device.For more information,you can contact Black Box at P.O.Box 12800, <br /> Pittsburgh,PA 15241,phone:(412)746-5500,fax: (412)746-0746,or at their Internet <br /> address http://www.blackbox.com <br /> Figure 20 illustrates how to connect two short-haul modems between the console RS- <br /> 232 Interface Module's or Auxiliary RS-232 Interface Module's DB-25 connector <br /> and the remote device. <br /> 47 <br />
