  • Page 13: Introduction

    Introduction INTRODUCTION Zetron Model 640 Paging Terminal MODEL 640 OVERVIEW The Model 640 is a low cost, fully automatic dial-access paging terminal. The Model 640 is specifically designed to provide flexible paging for industrial plants, hospitals, and low RCC applications. The Model 640 supplies the interface between the telephone and radio systems for paging applications.

  • Page 14: Telephone Interfaces

    Voice Storage The Model 640 DAPT XTRA stores up to 280 seconds of pooled voice storage to support voice pages. The silence compression feature eliminates pauses in the caller’s voice message to maxi- mize storage space. The voice memory also is used to save messages that are interrupted by a breakthrough page for later retransmission.

  • Page 15: Remote Transmitter Control

    The Model 640 can control any transmitter capable of decoding analog Motorola PURC® tones. A Zetron Model 66 Transmitter can be added to control other types of transmitters that do not use the PURC® protocol.

  • Page 27: Hardware Overview

    Hardware Overview HARDWARE OVERVIEW MODEL 640 ARCHITECTURE The Model 640 consists of several circuit boards in a compact, computer-like chassis. The basic unit is comprised of the main processor motherboard, a peripheral motherboard, a dual trunk interface, a ROM disk board, and a RAM disk board. In addition to the standard boards, a TNPP, TAP outdial, or dual serial board can be added for networking purposes.

    An uninterruptible power supply (UPS) option (Part No. 802-9049) obtains standby power from storage batteries and keeps the system operating through brownouts and blackouts. Zetron’s stan- dard UPS is a 400 VA unit with built-in batteries that provide 30 minutes of emergency power.

  • Page 30: Dram Memory

    Hardware Overview DRAM Memory The DRAM memory (item #3, Figure 2) physically resides in one or more single in-line memory module (SIMM) units installed into J9, J10, and J11. The base area of DRAM memory is loaded with the operating software for the Model 640 paging terminal. This plug-in board is also used for non-volatile storage of the subscriber database.

    Hardware Overview Adjustment Pots Three adjustment pots (item #14, Figure 3) on the peripheral board control audio levels to and from the radio station card. They are accessed from the rear panel of the Model 640 chassis. The RX adjustment controls the audio input level for the talkback feature. The TONE adjustment controls the paging tone output level to the transmitter, while the VOICE pot controls the voice audio output level to the transmitter.
