All connections are on the rear panel. Note – due to I/O limitations on the microprocessor, the Lantronix Serial port, the USB port, and the Aux/Com 1 port are shared so you can connect through only one of those three connectors at a time. To select the Lantronix RJ45 as the input, you must flip the Network DIP switch to the “LAN” position. This option is selected if the transmitter must talk to a remote server. To connect to the USB or Aux/Com 1 port, you must flip that switch to the “Local” position. This option is selected if the transmitter will run stand-alone, or connected to a local server through the USB port. When the switch is in the “Local” position, the USB dominates because the transmitter will detect the power voltage and automatically switch the internal connection to the USB port, so if the transmitter is connected to a server locally through the USB connection, the Aux/COM 1 port is deactivated. If a standard RS232 cable is plugged into the Aux/Com 1 port, that port then is the input, as long as the switch is in the “Local” position and there is no USB cable attached.

New transmitter Document: 1014.100 ECN: 1.10 Page 9 of 14 Confidential Document 2.2 XR Transmitter Set Up 2.2.1 General Set Up Considerations The XR transmitter should be located in an area that maximizes the propagation of the signal to the largest area in the facility. The FCC license needs to be applied for and granted before the equipment can be set up and operated. The channel switch setting on the back of the transmitter must match the channel authorized by the license. Set the transmitter on the supplied shelf, if purchased, or on another rack or mounting device as desired. If the rack mount option is used and the transmitter is mounted in a rack, the transmitter must be on the top of the rack and the rack must not have a top cover or it will interfere with the operation of the transmitter. For better transmission it is recommended that the XR transmitter be located a minimum of 3 feet above the floor and away from large metal objects, such as lockers, cabinets, ladders, power distribution panels, communications or computer racks, metal or shielded walls, etc. The antenna radiates in a circular pattern, therefore the coverage for an area will be better when the transmitter is more centrally located than when the transmitter is in the corner of a building. In a multi-story building, locating the transmitter nearer to the top of the building often gives the best coverage. 2.2.2 Hardware Set up Prior to plugging the supply into the wall outlet and the jack into the back of the transmitter, the following set up steps must be performed: 1. Connect the 46” whip antenna to the top of the XR transmitter on the NMO antenna mount. Be very careful to start the antenna base square and not to cross-thread the antenna base onto the connector. When connected properly, the antenna base will seat flat against the transmitter case top. 2. Set up the time synchronization input for the transmitter to one of the following options: a. If this is a GPS synchronized master transmitter, install the GPS receiver outside using the supplied mounting hardware, or in a window near the transmitter if the GPS will not be mounted outside. The GPS receiver should have a full view of the sky whenever possible to get the best signal and the quickest synchronization time possible. NOTE – the GPS receiver will not receive a signal through Low E Glass. Make sure the NTP/GPS switch on the back of the XR transmitter is in the GPS position. The 7-Pin MiniDIN connector from the GPS receiver or extension cables must be plugged into the GPS IN connector on the back of the XR transmitter. b. If this is a satellite transmitter synchronized by a repeater, mount the repeater on the wall as far away from the transmitter as possible. The transmitter/repeater combination should be located within receiving distance of the master transmitter. You can determine if the repeater is receiving the signal if the master GPS transmitter is broadcasting by powering up the repeater. After approximately 20 seconds, the green LED on the repeater should be flashing indicating that it received the signal from the master GPS transmitter. Make sure the NTP/GPS switch on the back of the XR transmitter is in the GPS position. The serial cable from the repeater must be plugged into the GPS IN connector on the back of the XR transmitter. c. If this is a network synchronized transmitter with a wired network connection, you need only connect the supplied CAT 5 patch cable to the NETWORK LAN connector on the back of the transmitter and then to the RJ45 wall jack that was set up for the transmitter’s network connection. Make sure the NTP/GPS switch on the back of the XR transmitter is in the LAN position. d. If this is a network synchronized transmitter with a wireless connection, you need to make sure that there is a wireless access point within receiving distance of the XR transmitter. Make sure the NTP/GPS switch on the back of the XR transmitter is in the LAN position.
New transmitter Document: 1014.100 ECN: 1.10 Page 10 of 14 Confidential Document e. If this transmitter is to be locally connected to an XR server, the CAT 5 cable from the server must be plugged into the NETWORK LAN CONNECTOR on the back of the transmitter. Make sure the NTP/GPS switch on the back of the XR transmitter is in the LAN position. 3. Set up the communications configuration: a. If this is a standalone transmitter with no network connection, set the LAN/LOCAL switch to LOCAL. b. If this transmitter has a network connection, wired or wireless, and the scheduling and other communications will be done via the network connection, then set the LAN/LOCAL switch to LAN. 4. Make sure the rotary CHANNEL NUMBER switches are set to the channel number that is authorized for this transmitter by the FCC license. 5. Set Up the remaining switches to match your locale and desired set up for time calculations: a. The TIME ZONE switch should be set to the time zone offset for the locale. b. The -30M/OFF switch should normally be in the OFF position unless you want a -30 minute offset calculation to the time. c. The UTC+/UTC- switch should be set as follows: i. The UTC+ position is for time zones east of the prime meridian and west of International Date Line. ii. The UTC – position is for time zones west of the prim meridian and east pf the International Date Line. d. The ST/DST switch should be set to the ST position if you are in a locale that does not follow standard USA Daylight Savings Time practices and to the DST position if you’re in a locale that does follow standard USA Daylight Savings Time Practices. e. The 24H/12H switch should be set to the 24H position if you want to see time in the 24 hour military time format and to the 12H position if you want to see time in the 12 hour time format with AM and PM indicators. f. Example for an XR transmitter set up in the Central Time Zone with DST enable in 12 hour format would be: i. The TIME ZONE switch set to 6 since Central time is UTC -6. ii. The -30M/OFF switch is set to OFF (down). iii. The UTC+/UTC- switch is set to UTC- (down). iv. The ST/DST is set to DST (down). v. The 24H/12H switch is set to 12h (down). 6. Plug the supplied AC adaptor into a 120VAC outlet, then plug the DC output jack into the POWER connector on the back of the transmitter. Set up is complete.

It does not include the operation of the following: • High power transmitters or transmitters with external antennae. • Clocks, timers, repeaters, or switches. • The XR server or any of its software. o The network connection process for the transmitter to the server. • The Compusync switch or software. • The Scheduler software for bell schedules or transmitter intermittent operation schedules. 2.3.2 Power Up Sequence and the Front Panel Once power is applied, the three LEDs on the front panel shown in Figure 3 in Section 2.1.2 will all light up for approximately two seconds. After that, they will operate as follows: • Green LED. o Off when the transmitter is waiting to be synchronized or the output power amplifier has failed. o On when the transmitter is broadcasting. o Off when the transmitter was in a blinking green situation and power is cycled. o Flashing when the transmitter is disabled by the server or an internal schedule for intermittent operation • Yellow LED. o Off means the transmitter is synchronized with a time source correctly. o Flashes when the XR transmitter has not received valid GPS, Repeater, or NTP time for 48 hours or at initial power up until synchronization occurs. • Red LED. o Off means there are no errors recorded in the internal error log. o Flashing means there is an error recorded in the internal error log. Errors can be viewed in the error logs by following the instructions in Section 2.3.2 under Menu 1 for Diagnostic Error Codes. After power is applied the LCD screen on the front panel of the XR transmitter will light up. The display will look different depending on the start up conditions: • If the XR transmitter has not recently been powered up, the time will start at 00:00:00 if in the 24 hour mode are at 12:00:00 am if in 12 hour mode and there will be no parentheses to the right of the GPS tower symbol which indicate that the transmitter is synchronized and the green LED will be off indicating that the transmitter is not broadcasting. • If the XR transmitter was recently powered up, within the last 8 hours, the internal battery back up clock will set the time immediately, and the LCD will come up with the correct time and date, there will be parentheses to the right of the GPS tower symbol, and the green LED will be ON, indicating the transmitter is broadcasting. • If the XR transmitter is hooked up to a repeater, the GPS tower symbol will be replaced by an “R”. • If the XR transmitter is loaded with a transmitter intermittent operation schedule and during this time period the transmitter is scheduled to be disabled, then even if the transmitter is synchronized, the green LED will be flashing, indicating that the transmitter power output is good but is not currently broadcasting.
