lines coming from each remote monitor. In this type of system, there is a modulator/demodulator (modem) at the main computer and at each remote site, usually built into the remote monitor itself. Since the cost of leasing a dedicated-pair phone line is quite high, wireless technology is often used as a cost-effective alternative. -
Page 18: Continuously-Keyed Versus Switched-Carrier Operation
Continuously-Keyed versus Switched-Carrier Operation The keying behavior of the master station can be used to describe the operation of an MAS system. Continuously-Keyed operation means the master station transmitter is always keyed and an RF carrier is always present, even when there is no data to send. -

Page 28: Step-By-Step Installation
5.0 STEP-BY-STEP INSTALLATION In most cases, the steps given here are sufficient to install the trans- ceiver. Refer to “INSTALLATION PLANNING” on Page 8 for addi- tional details. 1. Mount the transceiver. Attach the mounting brackets to the bottom of the transceiver case (if not already attached), using the four 6-32 x 1/4 inch (6 mm) screws supplied. -
Page 29: Initial Startup & Checkout
5.1 Initial Startup & Checkout In-service operation of the transceiver is completely automatic. Once the unit has been properly installed and configured, operator actions are limited to observing the front panel LED indicators for proper operation. If all parameters are correctly set, operation of the radio can be started by following these steps: 1. -
Page 30: Serial Vs. Telnet Access, And The Device Manager
Serial vs. Telnet Access, and the Device Manager There are three methods available to communicate with the transceiver for configuration and management purposes: Serial ( DB9 con- COM1 nector), Telnet ( RJ-45 connector), and the web-based ETHERNET Device Manager. Both serial and telnet present identical screens, but the method of access is different for each. -

Page 50: Troubleshooting
7.0 TROUBLESHOOTING Successful troubleshooting of the radio system is not difficult, but it requires a logical approach. It is best to begin troubleshooting at the master station, as the rest of the system depends on the master for polling commands. If the master station has problems, the operation of the entire network might be compromised. -

Page 58: Upgrading The Radio's Firmware
SQUELCH AUTO 8.5 Upgrading the Radio’s Firmware From time to time, GE MDS releases new firmware for its radio prod- ucts to take advantage of engineering improvements or to add opera- tional features. New firmware can be installed into existing radios in the field, bringing them up to date with the firmware shipped with new units. -
Page 59: Web Method
Three methods can be used to load new firmware into the radio: Web reprogramming, TFTP, and Serial Transfer. Firmware reprogram- ming is best handled using the web-based Device Manager. Instructions for these methods of transfer are given below, beginning with Web pro- gramming. -
