2.4 Hardware Description The MDR100A-R5 or MDR112A-R5 provides a fully enclosed, standalone modem, requiring only cabled connections. The MDR100A-R5 or MDR112A-R5 can be used on a table top surface or mounted on a flat surface or a wall using the mounting holes. - Page 12 Chapter 2: Overview Table 2-2.

Page 14: Operating Modes
3.1 Command Mode In this mode: • The MDR100A-R5 or MDR112A-R5 module is offline (data is not passing through the unit via it’s local data lines or RF communications). • The MDR100A-R5 or MDR112A-R5's configuration options (registers) may be viewed and modified. -
Page 15: Slave
Chapter 3: Operating Modes If a local device is attached to a Repeater‘s serial data port, the Repeater will also behave as a Slave (aka Repeater/Slave). Adding one or more Repeaters within a network will HALVE the throughput; the throughput is halved only once, i.e., it does not decrease with the addition of more Repeaters. -
Page 16: Network Topologies
Chapter 4: Network Topologies 4. Network Topologies The MDR100A-R5 or MDR112A-R5 may be configured to operate in a number of different operating modes and participate in various network topologies. NOTE: This section describes network topologies and also contains details about related factory default settings to enable the reader to readily see the correlation between various registers. - Page 17 Chapter 4: Network Topologies Figure 4-1. &F6 Master Configuration View. The screen captures on this page clearly show that most of the registers in both the Master and the Slave have the same values. (S105 is not visible in the Master view: its value is, and must be, 1.) The differences are S101 (Operating Mode), S105 (Unit Address), and S140 (Destination Address).

The factory default PMP Master configuration reveals the following differences with respect to the PTP factory default Master: S133=0 (PMP network) and S140=65535 (the broadcast address, indicating that this Master [point] will send its data to all modems—multipoint).
-
Page 20: Point-To-Multipoint Tdma
Chapter 4: Network Topologies In Figures 4-3 and 4-4, the difference between the factory default for the PMP Master and PMP Slave are simply the Operating Mode (S101), Unit Address (S105), and the Destination Address (S140). With the exception of the Master modem, all modems in a PMP network have a Destination Address of 1—the UA of Master modem—to which all data is destined. -

This Slave will transmit all of its data and then inform the Master of the same. -
Page 22: Gps Indexed Tdma (Adhoc)
Chapter 4: Network Topologies To view the current TDMA table, issue the AT&R1 command on the Master. The Master unit is always present in the TDMA list as unit address 1. 4.2.3 GPS Indexed TDMA (ADHOC) For GPS applications, GPS TDMA may be an ideal operating mode for some customers. Unlike other types of TDMA, GPS TDMA doesn’t use master units to synchronize and maintain timing of the network. - Page 23 Chapter 4: Network Topologies At the start of a Fast TDMA Frame, the Master unit sends information to all the units in the TDMA network. Included in this information is: 1. SYNC Packet—used for system synchronization. 2. TDMA Table/List—This is the list of all the addresses of all the remote units in the network, as well as the order and frequency in which they are to transmit data.
- Page 24 Chapter 4: Network Topologies Example: You have a system with 5 remotes and 1 master as shown below: Slave 2 Slave 22 UA = 2 UA = 22 Slave 11 Master UA = 11 UA = 1 Slave 7 Slave 5 UA = 7 UA = 5 Figure 4-6.
- Page 25 Chapter 4: Network Topologies S212: Max Expected Packet Size—(Set only on Master). S212 is the maximum packet size the remote units can send to the master, therefore defining the duration of the data slot for the remote units. The remote S112 register must be equal to or less than the value of the master’s S212 register.

Section 5.0 detailed the various network topologies that the MDR100A-R5 or MDR112A-R5 will support. Determine which topology meets your specific requirements. Throughput The MDR100A-R5 or MDR112A-R5 is capable of 230.4 kbps asynchronous serial data throughput. The network topology has an effect on how this available throughput is “shared” between all nodes on the network. Distance The physical distance between the modems determines the required antenna performance and heights, and whether or not a Repeater(s) is required. -
Page 50: Path Calculation
Power Requirements The MDR100A-R5 or MDR112A-R5 may be integrated into a system that accepts a range of DC input voltages (supply current requirements must also be met). In some deployments, power consumption is critical. A number of features related to minimize power consumption are available with the MDR100A-R5 or MDR112A-R5 Series: sleep/sniff modes, LED dimming, and the ability to operate at less transmit power given the receive sensitivity of the distant modem. -
