RS232/485 INTERFACE KEY
Transmitter ID (Tx ID)
is part of the Frontier transmitter addressing. A complete address is a combination of the
Frontier transmitter ID number, the transmitter or receiver point number on a Frontier unit, and facility code. Transmit-
ter ID can range from 1 to 65,000. The Frontier Tx ID and point number must be included in most data packets. The
transmitter ID and the point number identify the Frontier field device and the data point on that device. The facility
code is common or global to all radios communicating with the Frontier Gateway, so it is only sent once in the Global
Configuration Packet. A Frontier field receiver has no Tx ID but is programmed using Tx IDs to respond to a related
transmitter and point number.
TXD is RS232/485 transmitted data from the user’s device and the Frontier Gateway network interface key.
Unit Type
is the type of field receiver or transmitter. Refer to the "FRONTIER UNIT SELECTION" in Table 2 for set-
ting this value. Note that this selection affects the scaling of the data. If incorrectly set, the resulting transmitted or
received data may also be incorrect. Data type is set in configuration packets 2 and 3.
Upper Limit, Lower Limit are the values used by the network interface key for scaling data from the Frontier field
devices. Refer to Table 2, "FRONTIER UNIT SELECTION" for the correct values. Digital (On/Off) must also be set
based on this table.
User Device
is the user’s communications interface to the Frontier Gateway. This device transmits and receives data
from/to the network interface key via the RS232/485 hardware port.
