MPRX-FH User Guide Connecting the Antenna(s) To test the MPRX-FH, connect the antenna and power supply as described in this section. Discharge Voltage from the Antenna Caution During shipping and installation, an antenna can build up a very high voltage charge. The voltage needs to be discharged before connecting the antenna to the reader.
Chapter 2 Test Procedures CAUTION TransCore does not recommend using a screwdriver or other tool to short the RF cable center conductor to the outer ground of the cable. This grounding method can damage the center pin or the threads of the connector. Figure 9 Short Load to Earth Ground 4. Disconnect the grounding RF cable from the antenna and connect the permanent RF cable to reader.
MPRX-FH User Guide Connecting the Reader and Antenna 1. Ensure the reader is turned off and power is disconnected. 2. Connect one end of the RF interface cable to the antenna. 3. Connect the other end of the RF interface cable to the appropriate antenna port on the end of the MPRX-FH. Refer to Figure 10. 4. The ports can be turned on in consecutive order. If all four ports will not be used, start with Port 0 and turn on connected ports. Unused ports should be set to OFF.
Chapter 2 Test Procedures Connecting the Power Supply Caution To avoid damage to the MPRX-FH, first connect the reader to Earth Ground using a ground cable and stake before powering up the reader or connecting to an antenna. TransCore recommends following the National Electric Code or equivalent code for surge protection for the locale where the MPRX-FH is installed. A minimum of 18 AWG wire to earth ground is required for protective earthing.
MPRX-FH User Guide 2. Connect the MPRX-FH to a power supply using the host interface cable. The Sense and Host ports on the MPRX-FH are M23 connectors (Figure 12). Table 7 lists the pin assignments for the Host connector and Table 8 lists the socket assignments for the Sense connector.

The MPRX-FH should be connected to power with an external fuse to protect both the MPRX-FH and power source.
MPRX-FH User Guide Interface Selection Switch The MPRX-FH incorporates a communications interface selection switch, which allows on-the-fly changes to the communications mode. This switch allows selecting the reader’s receive communications interface. All communications interfaces are configured for simultaneous transmit, but only the interface selected by the switch is active for commands transmitted into the reader.
Chapter 2 Test Procedures SENSE 1 must be closed when a rail car is present on the track connected to MPRX-FH antenna ports 2 and 3. The reader RF switches on to the appropriate RF ports immediately upon detecting SENSE x. Sense Output Circuit The sense output is dedicated for testing and reader setup. It is defined as the TAG_LOCK signal, which indicates a valid tag is in the read field. This sense output is a dry contact that provides a normally open and normally closed sense output.

Chapter 3GeneralSoftwareInformation Chapter 3 General Software Information Command Entry Conventions All MPRX-FH commands are preceded by the start-of-message character (#). The end-of-message sequence expected from the host is a carriage return (CR). The MPRX-FH terminates messages with a return and a line-feed (CR/LF). For example, the command #01 Switch To Command Mode is typed as follows: #01 where is the Enter or Return key. Some command characters may be represented by the letter N.
MPRX-FH User Guide Table 11 shows an example of a command/reply sequence. This example assumes that an MPRX-FH with serial number SN97001P running version X.XX software is connected to a PC running a terminal emulation software package. The command sequence verifies that communications are working correctly. Table 11 Sample Command Sequence Entry MPRX-FH Response Notes #01 #Done Switches MPRX-FH to command mode #505 #Model E4 Series Ver X.
Chapter 3GeneralSoftwareInformation Download Considerations You should consider the following factors when performing Program Download: • The MPRX-FH does not process tags while in download mode. • The MPRX-FH does not accept any program data unless a successful erase of flash memory has been performed before transmitting the data. Erasing the flash memory typically takes two seconds. • Cycling reader power after exiting from download mode re-executes startup.
MPRX-FH User Guide Boot Failure Message Upon powering up, the software performs a checksum verification on itself. The function returns a specific value for the particular version of software. If the value returned is not correct, the boot code assumes that the application code has been corrupted and a failure condition exists. If the failure message does not transmit, a communications error has occurred or the boot has failed to the extent that it cannot transmit the failure message.
Chapter 4 Communications Protocols Chapter 4 Communications Protocols Introduction The MPRX-FH supports the following communications protocols: • Basic • Error correcting • Data inquiry The following protocol information provides reference information relevant to developing host software. Communications are performed using the 7-bit ASCII code with optional parity, providing easy setup, testing, and diagnostics with standard ASCII terminals and serial printers.
MPRX-FH User Guide Basic Protocol With basic protocol, messages sent to and from the MPRX-FH and the host are transmitted without error checking. For each host transmission, the MPRX-FH returns a #Done or #Error message to the host. When the host device is physically close to the MPRX-FH and no sources of interference exist, the basic protocol provides reliable communications.
Chapter 4 Communications Protocols Data Inquiry Protocol Data inquiry protocol is a basic protocol option that allows the host to control transmission of reader tag data. The selection of data inquiry protocol affects data mode operation. As MPRX-FH acquires tags, it buffers them but does not transmit them. Instead, the host must poll MPRX-FH for each tag by sending a CTRL-E character (hex 5 digit). MPRX-FH transmits one message (tag ID or report data) for each CTRL-E it receives until the buffer is empty.
MPRX-FH User Guide When the host receives a properly framed message, it can calculate a 16-bit CRC value. The calculation is applied to the character string that immediately follows the and that ends with the character immediately preceding the first character. Transmitted CRC value can then be compared with the binary equivalent of the received characters.
Chapter 4 Communications Protocols Switch to Command Mode Request The host device may issue command #01 Switch to Command Mode while in data mode.
MPRX-FH User Guide Command code, a string that contains from two to four ASCII hex characters [] Optional data field, an ASCII string of as many as 20 characters in length. For example, the store hardware configuration string command is #696S...S or command #696 Store Hardware Configuration String followed by the data string S...S.
Chapter 4 Communications Protocols where # Start-of-message character 4 Message sequence number KING 1302 Message data: Tag ID is shown.
MPRX-FH User Guide Timing and Synchronization The ECP is largely independent of baud rate. The timeout delays previously described are a function of baud rate. The MPRX-FH supports an ECP timeout, which applies equally to both transmit and receive. The receiver’s minimum timeout delay equals the time to transmit/receive the longest anticipated message at the current baud rate setting. Additional margin should be included for idle periods between characters; for example, processing overhead, if any.
Chapter 4 Communications Protocols If the message recipient receives a second character before an character, the message acquisition is aborted (reset), and retransmission of the previous message is assumed to be underway. These strategies allow for recovery during periods when communications are marginal or lost completely. Reader-Addressed Failure Conditions The MPRX-FH addresses the following failure conditions.
MPRX-FH User Guide Incorrect CRC If the host detects an incorrect CRC value in a reader message, it retransmits the command with the same sequence number. If the host detects an incorrect CRC value in an asynchronous reader transmission, it transmits a NAK message. Transmission Timeout If the MPRX-FH does not respond to a host command within a specified interval, the host software retransmits the command with the same sequence number.
Chapter 4 Communications Protocols Example 1 presents an example of a function (CALCCRC) that calculates the CRC value through a call to a separate function (UPDCRC). unsigned short calccrc(char *message) { unsigned short crc = 0; for ( ; *message != (char)0;message++) crc = updcrc(*message & 0xff, crc); return (crc) } Example 2 shows an example of UPDCRC that does not require a lookup table.
MPRX-FH User Guide Example 3 contains an example of UPDCRC that does require a lookup table.
Chapter 4 Communications Protocols Example 4 shows an example of a function that creates the lookup table. #include
MPRX-FH User Guide You must acknowledge existing messages by issuing commands with the generic format: #x@‘‘‘‘ where # Start-of-message character x Message sequence number. This must be the same as the sequence number of the message being acknowledged @ ACK (acknowledgment character) <‘‘‘‘> Wild card CRC value for the message End-of-message character The following is a typical sequence after power-on limiting buffered messages.
Chapter 5 Commands Chapter 5 Commands Default Settings The MPRX-FH is delivered from the factory with specified default settings that determine how the reader operates. Commands transmitted by the host device can change the default settings and control additional features. The commands can be transmitted by manually entering the commands at the host keyboard if the host is in terminal emulation mode. The MPRX-FH can also communicate with ASCII terminals.
MPRX-FH User Guide 1. If the host device receives the #Done message, then both the host and the MPRX-FH switch to the new baud rate, and communications are maintained. Note: In many applications, the host must be set to the new baud rate as it does not change automatically. The MPRX-FH changes the baud rate immediately after issuing the message. 2.
Chapter 5 Commands Caution To save user parameter changes to non-volatile memory (NVRAM), you must send Command #00 before powering down the reader. When MPRX-FH mode has been enabled (#837) and while the MPRX-FH is in data mode, the host device can send the following commands to the MPRX-FH: #01 Switch to Command Mode Reader response: #Done #440 Reset Uniqueness Reader response: #Done Note: The MPRX-FH transmits ID codes to the host device when the MPRX-FH is in data mode.
MPRX-FH User Guide 101N Select Stop Bits selects the number of stop bits for reader character transmission. The factory default setting is 1 stop bit. The N variable specifies the number of stop bits as indicated in Table 13. #101N Table 13 Select Stop Bits Commands Command Stop Bits Selected 1010 1 (factory default) 1011 2 Reader response: #Done 102N Select Parity selects the reader parity setting. The factory-default setting is parity disabled.
Chapter 5 Commands If hundredths of a second is not specified, the reader sets the hundredths register to 00. Reader response: #Done 21 Set Date #21 sets the date. Enter the date in the proper format: two-digit decimal entries with no spaces between characters and using forward slashes “/” as delimiters. The entry format is as follows: 21MM/DD/YY where MM represents the month (01 to 12). DD represents the day (01 to 31). YY represents the last two digits of the year (00 to 99).
MPRX-FH User Guide The reader returns an #Error message if its tag buffer contains data. The reset reader Command #63 may be transmitted to clear the buffer; however, tag ID data will not be reported. If this is unacceptable, allow the buffer to empty before reissuing append time and date Command #30N Append Time and Date commands are shown in Table 15.

Start the terminal emulation application as described in “Starting the Terminal Emulation Software” on page 6–85. Note: When testing the MPRX-FH using a laptop computer, TransCore recommends that you configure laptop communication parameters to match those of the host device to which the MPRXFH will be connected after testing and configuration are completed. 2.
Chapter 6 Configuration To check connections and communications factors 1. Confirm that the MPRX-FH has power. 2. Verify the connections between the PC and the MPRX-FH. 3. Verify the receive (Rx) and transmit (Tx) connections. 4. If using handshaking, verify the request to send (RTS) and clear to send (CTS) connections. 5. Verify the COM port settings for the MPRX-FH following the instructions in “Serial Port Communications” on page 6–92 .
MPRX-FH User Guide To verify tag read capability 1. Once communications are verified, enter the following sequence of commands to turn on continuous RF: • #01 • #6401 • #40 • #00 2. Pass one test tag in front of the active MPRX-FH antenna. If the MPRX-FH reads the tag, the terminal emulation application displays the tag information on the screen. 3. If the tag ID is not displayed, perform the following actions: • Verify that the MPRX-FH is in data mode (Command #00 Switch to Data Mode).
Chapter 6 Configuration The following sections contain procedures to set some of the parameters that are commonly changed to meet the requirements of a specific site. Procedures are listed in alphabetical order by parameter. Appended Tag Data Use this procedure to set appended tag data parameters using the terminal emulation application.
