DSX Access Systems, Inc. 10731 Rockwall Road Dallas, Texas 75238 888-419-8353 Sales, Shipping and Accounting 800-346-5288 Technical Support 214-553-6140 Phone www.dsxinc.com 214-553-6147 FAX Modem 02/05 Modem Operation Overview The DSX System is capable of communicating with multiple remote locations via dial-up phone modems. A baud rate of 9600 is required for DSX Intelligent Controllers. Each location may be treated as a separate system, or locations may be grouped together to form a larger access control system. Since the system is fully distributed and does not require a PC for operation, there is no loss of performance in systems using dial-up phone modems. All controllers retain all capabilities including card access, anti-passback, and I/O Linking. The PC may be programmed to routinely poll each modem-controlled remote location from 10 to 65,534 minutes. Poll Times set lower than 10 minutes can affect the performance of the system. Routine Polls provide verification that communications are still functioning and the collection of history logs. If the PC fails to connect with a modem location on three consecutive attempts, a Location Communications Loss alarm is generated at the PC and an optional action message can be displayed instructing the operator on what action to take. If the PC is not programmed to routinely poll the location Master, the Master controller can be programmed to automatically store all transactions until the history buffer reaches 80% of capacity. When the buffer is at 80%, the Master controller calls the PC to upload all transactions. If an alarm event occurs, the Master will initiate a call to the PC to report the alarm event regardless of its buffer status. If the Master controller is reset for any reason, it will automatically call the PC and request a full parameter download to ensure proper operation. 1 When database changes occur, the system will initiate a call to the remote site at the earliest time possible when the modem and phone line are available. The System can be programmed to delay downloads for a programmable number of minutes or set for after hours downloading which defers the downloads until the first convenient time between the hours of 1:00 and 5:00 AM. Modem Recommendation DSX recommends the DSX series modems for dial up phone line or leased line communications. This series of modems are small dial up phone modems that may be powered from the 12VDC Reader Port 12V output of the DSX Controller. By powering the modem from the controller, the modem is battery backed up so that communications will occur even during an AC power loss. DSX configures and initializes all modems before shipping. They are shipped with everything necessary for installation. These are the only modems DSX will support. Other modems may or may not work properly. Phone Call Description During an incoming call at the PC, the modem transmits a ring signal to indicate that the line is ringing. The PC then commands the modem to go Off-Hook (OH). The two modems form a link by transmitting a carrier tone through the phone line. At this time, the modem will turn on the Carrier Detect (CD) light. Communication will then proceed between the Master and the PC at the 2 defined baud rate. The PC is always responsible for dropping the connection (hanging up the phone). The Master's modem hangs up when the connection is dropped. The PC modem must be initialized before it will function properly. Each time the communications program is started, and before each outbound call, the modem is automatically initialized. If the modem loses power, or is turned off and then back on, it must be re-initialized. To manually re- initialize the modem, perform a manual connect and disconnect or exit the communications program and return. Communication Security Password (Location Password) WinDSX downloads the Communication Security Password (Location Password) into the non- volatile memory of the Master Controller. Once the Master Controller is downloaded with the Location Password, the password is required for all dial-up modem communications to that location. The Location Password entry is located under Location in Database. In the WinDSX Software the Location Password is not downloaded into Direct Connected Masters. Changing the password requires knowledge of the password and communication with the Master Controller using KB2CW.exe. This terminal emulation program will prompt the operator to enter the password and then allow the operator to change it by issuing the PW command. To change the password without exiting the DSX program requires completely resetting the controller by powering the controller down and up. 3 DSX Modem LED Operation HS Always On when initialized at 4800 baud or higher. HS AA On at PC when call is ringing in. Stays On at Controller once Controller has AA initialized. Modem to answer on third ring. CD CD On during communication session. OH OH Normally Off and turns On when the modem goes off hook. RD RD Normally Off and flashes On to indicate the PC is receiving from the modem. SD SD Normally Off and flashes On to indicate the PC is sending data to the modem. TR TR Always On and flashes at PC before connecting and disconnecting. MR MR Always On at PC and at DSX Controller when modem has power. Modem to PC Connections DSX Modem to PC Comm Port 1 or 2 Use supplied AT modem cable to connect the modem to Comm 1 or 2 on the PC. DSX Modem to Digi Board Use supplied AT modem cable to connect the modem to the outboard serial connection a Multi-Serial-Port Communications Board. DSX Modem Power Connections at PC Use the supplied DC power adapter to power the modem when used at the PC. Connect the DC power adapter to the same AC power source as the PC. 4 PC Baud Rate At the Host or Comm Server PC, set the communications port baud rate to match the baud rate set in the Master Controller, which is typically 9600 baud. Modem Power Sources The DSX modem will accept AC or DC power. Power the modem from the I/O board 12V Reader power output when used at a DSX-1022, DSX-1020 series, DSX-1032 or DSX-1042 controller. When the modem is placed at the PC use the supplied plug in power adapter.
