Any device on the left that requires a keyline, as in this illustration, will
require the bottom line (CTS to RTS) and the TransNET on the right will need
DEVICE type set to CTS KEY. See DEVICE, on Page 32 for details.
4.4 Configuring a Network for Extensions
The installation and configuration of an Extension transceiver is straightfor-
ward with only a few unique parameters that need to be considered and set at
each unit.
In every network there can be only one Master station. It will serve as the sole
gateway to the outside world. The tables in “Configuration Parameters for
Store-and-Forward Services” on Page 57 detail the parameters that need to
be set on each type of radio in the network. For a detailed description of this
network design, see “SAF Operation with Extension Radios” on page 52.
5.0 OPERATION
5.1 Initial Start-up
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 LED status indicators for proper operation.
If all parameters are correctly set, start operation of the radio as follows:
1. Apply primary power.
2. Observe the transceiver LED status panel for proper indications. Table 6
provides an explanation of the LED functions.
In a normally operating system, the following indications will be seen
within 16 seconds of start-up:
•
PWR lamp lit continuously
•
SYNC lamp lit continuously
