ITCR Wayside User’s Manual 1. Overview This document provides information required for the operation and verification of the Meteorcomm Interoperable Train Control Radio Network (ITCR) Wayside radios. 1.1 Applicable Radio Models and Identifiers This document applies to the Wayside radio model listed below along with its regulatory identifiers. Model: 63010 FCC ID: BIB63010 IC: 1300A-63010 1.
ITCR Wayside User’s Manual other possible track condition indicators. The WIU formats the status information into a short message called an aspect. The aspect is sent to the Wayside radio for packetized RF transmission. 1.3 Chassis Wayside radios are housed in electrically sealed metal cases. The Wayside radio dimensions are approximately 15.5W X 9.5 H X 2.0D. It weighs less than 8 lbs. All input/output ports are grounded and/or shielded.
ITCR Wayside User’s Manual 2.2 Limiting RF Exposure Please refer to the RF Energy Exposure Guide packed with each radio for specific information regarding safe distances that must be maintained between personnel and energized transmitting antennas. The information in the RF Energy Exposure Guide is determined from FCC and Industry Canada rules that when followed, limit human exposure to radio frequency energy to acceptable levels.
ITCR Wayside User’s Manual • • • • • • • The licensee is required to comply with limits on antenna location, power and effective antenna height per 47CFR Subpart T §90.701 et. seq., or Industry Canada SRSP-512 §6.3 as applicable. Install antennas in accordance with the manufacturer’s instructions. Disable the transmitter when installing or servicing its antenna or transmission line.
ITCR Wayside User’s Manual 2.5 Equipment Modifications Caution: Any changes or modifications to this equipment not expressly approved by the party responsible for compliance (in the respective country of use) could void the user’s authority to operate the equipment. 3. Wayside Transmitter Operation It is the responsibility of the licensee to operate this radio transmitter in compliance with the terms of the license and FCC or Industry Canada service rules for 220-222 MHz, i.e.
ITCR Wayside User’s Manual Therefore, the wayside radio may not transmit on those channels or their 221 MHz counterparts, 361-370 and 381-385. This corresponds to wayside frequencies, 220.8125, 220.8375, 220.9125, 221.8125, 221.8375, and 221.9125 MHz. Please refer to Part 90 Subpart T and SRSP-512 for additional frequency use restrictions in Canadian and Mexican border areas. 3.
ITCR Wayside User’s Manual for 10 feet of Times Microwave LMR-195 Ultra Flex coaxial cable. Transmitter power output limit = 47-2.4+0.6 = 45.2 dBm PEP and therefore the system is compliant with the 50W ERP limit. The actual ERP in this case is 10^(14.85+2.4-0.6) = 46.2 W. This installation is not allowed to transmit on FCC channels 196-200 because the maximum ERP is greater than 2 watts.
ITCR Wayside User’s Manual 4.1 Power Supply Wayside radios operate at 13.6Vdc input. Table 1 describes the power supply requirements. Caution: Applying an incorrect voltage to a Wayside radio can cause damage. Confirm the voltage of the radio and the power supply before applying power. Table 1 Wayside Radio Power Parameters Parameter Wayside Radio Nominal DC Power Input Voltage 13.6Vdc Operational Range 10.9-15.
ITCR Wayside User’s Manual 5. Tuning the Wayside Radio There are three parameters to test and potentially tune before/during RF testing: • • • • Master reference crystal oscillator frequency RF output power RF output channel Factory technicians tune the master reference crystal oscillator and set the RF gain for maximum rated output power. You may have to adjust the three parameters before or during RF testing by entering commands using XtermW or another terminal emulation program. 5.

Use the Edit/Configure Port window to set Port Type = TCP/IP, Protocol = Stream, TCP/IP Settings Host = 10.10.1.254, Port 4000. Select Device Type = MCC 6100 SDR (which also applies to ITC radios). Return Character = CR, Data Format = ASCII. 4. Attach a 50W 30 dB RF attenuator to the TX/RX1 N-type antenna connector. Attach an (e.g.
ITCR Wayside User’s Manual 7. Set the VSA to the center frequency of the channel and set it to demodulate the 8 ksym/second π/4-DQPSK emission and measure the error frequency which is referenced to the VSA center frequency. To adjust the master crystal reference oscillator parameters: 1. First, check the factory default setting for the crystal reference parameter by typing cal 2. Note the value for “xo” in the cal factors table that is displayed. 3.

Tune the VSA to the center of the channel frequency and select the CCDF function to measure the peak (envelope) power, average power and peak to average ratio. Note that the peak envelope power is used for determining ERP. 5.
