It is important to select a cable that matches the radio‟s impedance.
Document Number: pnZXTxRM-0712m Figure 3-15 LMR100 Cable Cross Section Along with the type of cable, you need to select the correct connector. Our product uses an RPSMA Male (plug) connector. Therefore, you will need a cable that has a RPSMA Female (jack) on one end. If you are using one of the optional antennas, you will need an N type Male connector, since these antennas have an N type Female on them.
Document Number: pnZXTxRM-0712m Section Four – Electrical Installation 4.0 Electrical Installation Please see the Quick Start Guide for UL Class 1 Division 2 installation instructions. 4.1 Wiring 4.1.1 Terminal Block Both power and data signals are connected to the terminal block. Figure 4-1 shows the layout.
Document Number: pnZXTxRM-0712m 4.1.3 RS-232 Connections 4.1.3.1 RS-232 Signal Convention (DTE / DCE) There are two types of RS-232 ports, DTE (Data Terminal Equipment) and DCE (Data Communications Equipment). The signal names and pin numbers are the same, but signal flow is opposite. The pin labeled TD can be input, and RD the output. The two ports types are complementary, the Output signals on a DTE port are Inputs to a DCE port, and Output signals on a DCE port are Inputs to a DTE port.

There is also a built in 120 Ω termination resistor (R21). These resistors are located on the PCB behind the cover. Termination is switchable using DIP Switch Position 3. To enable the termination, set switch 3 to ON “Termination IN”.
Document Number: pnZXTxRM-0712m 4.1.7 Fault Output The radio modem has a sourcing (PNP) 50 mA output that is used as a fault indicator. This output is activated when the received signal strength drops below a critical level. To use this function, the RSSI indicator must be set to continuously update. This is accomplished by setting the RP-RSSI PWM Timer to FF in the diagnostics section of the advanced modem settings tab. See figures 4-7 and 4-8. Figure 4-9 shows the wiring connections.

For example, radio modem number 1 could be 0001 and radio modem number two could be 0002. Another option is to leave the destination address at its default value of 0000 and proceed to the next step.
Document Number: pnZXTxRM-0712m 9. On the Advanced Modem Settings Tab, under the Networking and Security Tab, select the Source Address (MY – Source Address). This sets the address of the modem and should be comparable with the destination addresses set above. For example, if you set the destination address on modem number two to 0002, the source address on modem number one should be 0002. Another option is to leave the source address at its default value of FFFF.

Document Number: pnZXTxRM-0712m C.2 Mounting The radio modem can be mounted directly to a panel or bulkhead or by attaching the supplied mounting ears. In either case, the cover must be removed to allow access to the screw pass-through holes. The mounting ears are packaged with screws. If you want to mount the device without using the ears, you will need to procure longer number 6 screws.

Document Number: pnZXTxRM-0712m Appendix D – Radio Frequency Basics D. Appendix D – Radio Frequency Basics D.1 What is dBm? Radio Frequency (RF) power is measured in milli-Watts (mW) or, more usefully, in a logarithmic scale of decibels (dB), or decibels referenced to 1 mW of power (dBm). Since RF power attenuates as a logarithmic function, the dBm scale is most useful. Here are some examples of how these scales relate: 1mW = 0dBm A 2-fold increase in power yields 3dBm of signal.
Document Number: pnZXTxRM-0712m You can often improve your receive sensitivity, and therefore your range, by reducing data rates over the air. Receive sensitivity is a function of the transmission baud rate so, as baud rate goes down, the receive sensitivity goes up. Many radios give the user the ability to reduce the baud rate to maximize range. The receive sensitivity of a radio also improves at lower frequencies, providing another significant range advantage of 900 MHz (vs. 2.
Document Number: pnZXTxRM-0712m D.6 Remember Your Math Contrary to popular opinion, no black art is required to make a reasonable prediction of the range of a given radio signal. Several simple concepts must be understood first, and then we can apply some simple rules of thumb.
Document Number: pnZXTxRM-0712m Beware leafy greens. While a few saplings mid-path are tolerable, it‟s very difficult for RF to penetrate significant woodlands. If you‟re crossing a wooded area you must elevate your antennas over the treetops. Industrial installations often include many reflective obstacles leading to numerous paths between the antennas. The received signal is the vector sum of each of these paths. Depending on the phase of each signal, they can be added or subtracted.
Document Number: pnZXTxRM-0712m While long cable runs to an antenna create signal loss, the benefit of elevating the antenna another 25 feet (7.6 m) can more than compensate for those lost dB. D.11 Latency and Packetization Before you lift a finger towards the perfect wireless installation, think about the impact of wireless communications on your application. Acceptable bit error rates are many orders of magnitude higher than wired communications.
