4.0 Connecting Data Devices The system provides two short-run serial data ports on the CPU board. The system designates these modular jacks as Modem and Maintenance. These two serial data ports are dedicated to the personal computer (PC) that you will use to load the programmed data base and to the remote servicing and programming modem that you will use to remotely load the programmed data base and troubleshoot the system. Since these serial data ports are short-run, you must keep the cabled distance between the data device and the data port to 25 feet or less. NOTE: If you connect a modem other than the DXMDM, you must interface that modem through a comunications card that you have installed on the services board or an auxiliary board. CAUTION When you are not using a PC for programming purposes, you should disconnect it from the maintenance port. It is possible for the idle connected PC to induce electrical interference that may affect system performance. Remember, a data cable must be no longer than 25 feet in length. When preparing a data cable for connection to a data device, refer to the manufacturer’s manual for the equipment being interfaced and make the following wiring connections: ·Wire the common equipment RD (data from device to common equipment) connection to the device TD (transmit data) connection. ·Wire the common equipment TD (data to device from common equipment) connection to the device RD (receive data) connection. ·Wire the common equipment SG (signal ground) connection to the device SG (signal ground) connection. ·If required for proper operation, wire the common equipment CTS (clear-to-send status from device to common equipment) connection to the device RTS (request-to-send) connection. NOTE: The common equipment requires a positive voltage, with respect to signal ground, in order to send data. ·If the cable has spare wires, be sure to ground them so that they will not act as antennas and induce interference into the system. Further, if there is a source of RF power nearby (such as a radio transmitter), use shielded cable and ground the shield at both ends. The default data format is shown in the following chart. Configure the data device that you connect to the maintenance port to match the charted information. Port Type Baud Rate Data Bit Stop Bit Parity Bit Maintenance Port9600 8 1 0 Modem Port 2400 8 1 0 CAUTION As an added precaution against induced interference, route the data cable as far away from any fluorescent lighting as you can reach, and make every effort to route the data cable perpendicular to other wiring.

6.0 Configuring The Common Audible Ringing Interface The services board provides relay actuation dry-contact terminals that you can use for controlling external ringing equipment. These relays are under programming control. You can program them to provide dry-contact actuations that track the ringing pattern of any of the programmed flexible ringing assignment ringing patterns. CAUTION Do not exceed a 1 amp at 24 volts (0.5 amp at 48 volts) load on these control terminals. If the load requirements exceed this limit, connect the load through an external slave relay. DO NOT CONNECT THESE CONTROL TERMINALS DIRECTLY TO THE 120VAC LINE.

7.0 Configuring The External Paging Interface A special transformer-isolated external paging port, located on the services board, provides system interface for an external paging amplifier. Connect a customer-supplied paging amplifier to the PAGE jack as shown in illustration. Remember, the Services board provides relay actuation dry-contact terminals that you can use for controlling the external paging amplifier. Of course, you must make the necessary wiring arrangements to match the control that you want to occur. Once you have made the necessary wiring connections, you may either: ·program any of the relays to provide dry-contact actuation that will turn on the paging amplifier for as long as the paging port is active, ·or program any of the relays to use their dry-contact actuations to track line ringing signals sent from the paging port. (This is useful for turning the amplifier on and off to sound these ringing signals.) CAUTION Do not exceed a 1 amp at 24 volts (0.5 amp at 48 volts) load on these control terminals. If the load requirements exceed this limit, connect the load through an external slave relay. DO NOT CONNECT THESE CONTROL TERMINALS DIRECTLY TO THE 120VAC LINE.
