Carrier 33CNOAANT1 ID Types, Advanced Settings, ID Type Explanation, Feature Explanation

Session Holdoff — (Adjustment of these settings is not recommended.)

This will only be enabled for a host transceiver and is re- quired to manage the communication from multiple remotes. It prevents a host unit from starting a new session until it com- pletes its current session. It keeps other devices from establish- ing a session with the host until the host has completed its cur- rent session with a particular device.

Assigning IDs — Using a combination of firmware and software assigned IDs, the security of the data is ensured. Some IDs can be modified and others cannot depending on your privileges. The IDs are all accessed either via Quick Configura- tion or the General Tab. See Fig. 16 and Table 5.

Table 5 — ID Types
ID TYPE	EXPLANATION
Vendor ID	Assigned at the factory and burned into the
	firmware. This number is not modifiable.
	This ensures that no other Carrier cus-
	tomer can intercept data assigned to the
	ID. There are 64,000 unique Vendor IDs.
Network ID	A number that identifies the network and
	makes it unique from other networks in the
	area. All units in a network must have the
	same Network ID. The Network ID allows
	the user to have multiple networks within
	the same transceiver space. There are up
	to 64,000 unique numbers. Units with dif-
	ferent IDs cannot communicate with each
	other.
Source Unit ID	For broadcast network communication, the
	source ID = 0 for the host and the source
	IDs for the remotes are 1.
Destination Unit ID	The numeric ID of the unit that the trans-
	ceiver being configured will communicate
	with. For a Broadcast network, the host will
	have a destination ID =1. The remotes will
	each have a destination ID = 0 (the host ID
	number)
Alias Source Name	A descriptive name for the unit.
Alias Network Name	A descriptive name for the network.

Signal Analysis — There are a number of features which can help you analyze the strength and consistency of your data signal. They are available via the Advanced Settings tab. See Table 6.

Table 6 — Advanced Settings

FEATURE	EXPLANATION
TX Power	The transmit power of the unit rela-
	tive to the possible power levels.
	The upper RSSI (Received Signal
Power Ctrl Upper Value	Strength Indicator) threshold which
	when surpassed causes the unit to
	reduce its transmit power.
Power Ctrl Lower Value	The lower RSSI threshold which
	when surpassed causes the unit to
	increase its transmit power.
Temperature	The operational temperature of the
	unit as reported by the thermistor
	in fractional volts.
	The RSSI averaged over the last
Local time-averaged RSSI	16 transmissions. Used in analyz-
	ing the strength and quality of the
	transmit signal.
	The value of RSSI for the last
Local instantaneous RSSI	transmission. Used in analyzing
	the strength and quality of the
	transmit signal.
D/A / A/D Loopback	Factory Diagnostic.

Unit Testing — You can test the operation of transceivers in a variety of ways using the Configuration Manager. The in- structions in this section assume that the Configuration Manag- er is correctly installed and the transceiver is properly connect- ed to your PC.

The test string is transmitted to the Destination Unit and looped back to the Source Unit. The RX Pane shows the test string as received by the transceiver connected to the computer after being loopbacked from the remote transceiver. If no data is received within the timeout period the message “Timeout” is printed in the RX Pane. The TX Pane shows the test string as typed in the dialogue box.

To perform a communication link test it will be necessary to use two Carrier wireless transceivers, two antennas, a loopback connector and a computer.

Perform the following tests:

•Terminal mode

•Loopback test (Stand-alone model only)

TERMINAL MODE TEST — The Terminal Mode tab pro- vides a simple terminal interface from which data can be sent between two units configured as a Broadcast Remote-to-All Host and Remote Pair. Anything typed in the input field of transceiver no. 1 will immediately be transferred to transceiver no. 2. The data is displayed in the transmit pane for transceiver no. 1 and the receive pane for transceiver no. 2. (NOTE: You will only see received data if the destination transceiver is con- nected to a PC with Configuration loaded and open or if the destination PC’s transceiver has a loopback connector.)

What You Need:

•Two transceivers (A and B) configured as a host to remote. The Source Unit ID of unit A equals the Desti- nation Unit ID of unit B and vice-versa. In addition, both units must have matching Vendor ID numbers, Network ID numbers and Hop Table numbers.

•One of these units is connected to a PC with the Config- uration Manager loaded.
