Page 7: Introduction
Modbus RTU or PNIM protocols to connect to the remote slaves. The QUCM con- figuration is accomplished by a built-in web page. The remote location includes a Niobrara MUCM to interface between the modem and the RS-485 network of slaves. This MUCM converts the Modbus ASCII messages to Modbus RTU or PNIM based upon the slave address of the Modbus ASCII message. - Page 8 25-pin modem. An MM1 cable is needed to load the IP Address into the QUCM. The Niobrara MU12 cable is used to connect the RS-232 port on the MUCM to a stan- dard 25-pin modem. The Niobrara METH-001 should be used to cover the option adapter on the MUCM.

Page 9: Installation
Serial Connections to the QUCM-OE Port 1 (and Port 2) to 25-pin DCE Modem The serial ports of the QUCM-OE must be switched to RS-232. The Niobrara cable MM12 is used to connect to a standard 25-pin Modem. NOTE: Do not use the MM4 cable for this application. -
Page 10: Port 1 To The Personal Computer
A physical connection must be made from the personal computer to the QUCM in or- der to configure the Ethernet parameters of the QUCM-OE. This link may be a serial connection from a COM port on the personal computer to the RS-232 port on the QUCM-OE. -

Serial Connections to the MUCM-002 Port 1 to 25-pin DCE Modem The RS-232 serial port of the MUCM is used to connect to the modem. The Niobrara cable MM12 is used to connect to a standard 25-pin Modem. NOTE: Do not use the MU4 cable for this application. -

Figure 2-7 MUCM to RS-232 PC Port (9-pin) (MU1 Cable) Loading the Applications into the QUCM The QUCM-OE must use the qucmtcpl.fwl or qucmtcpl.qcc firmware included in the modem.zip file. This firmware is dated 28Oct2002 or later. There are two ways to upgrade the firmware of the QUCM-LE: QLOAD and FWLOAD. -
Page 13: Using Zapreg32.Exe To Set The Ip Address
Using ZAPREG32.EXE to set the IP Address It is recommended to use the Ethernet capabilities of QLOAD to load the firmware, APP!.QCC and APP2.QCC into the QUCM. Set up the IP parameters of the module by the following method: Figure 2-8 ZAPREG32 COM1:9600,E,8,1 255 -B Move Switch 1 and Switch 2 to Halt. -
Page 14: Qload Qucm Firmware Update
(leave this alone) Modbus Port 503 (this defaults to 502) After entering the IP parameters, attempt to ping the module to verify the settings. > ping 206.223.51.161 Verify a connection to the internal Modbus/TCP server with zapreg32. > zapreg32 206.223.51.161:503 255 Should connect to the QUCM on port 503 with Destination index 255. -

Replace the module in the rack and apply power. Only the 3 light should be on. (The Link and RX E-net lights may be on if the E-net port is connected and there is traffic.) Connect the PC to QUCM Port 1 with a MM1 cable.. Make sure that Port 1 is set to RS232 mode with the slide switch below the port. -

Page 17: Qload Mucm Firmware Update
QLOAD MUCM Firmware Update QLOAD is a convenient method for upgrading the firmware of a MUCM. A direct serial connection to either port1 or port 2 on the MUCM is required. Application 1 and 2 Switches must be in HALT Start QLOAD.EXE Click on the Browse button and select the file mucm.qcc. -

Remove the module from the rack and change the switch back to RUN. QLOAD MUCMAPP1 Figure 2-11 QLOAD of MUCMAPP1 Application 1 and 2 Switches must be in HALT. Start QLOAD.EXE Click on the Browse button and select the file mucm_modem_app1.qcc. Select the Application 1 Radio Button. - Page 19 Select the Application 2 Radio Button. Verify the following: a. Status Register = 3. b. Run Pointer Register = 33. c. Auto Start is NOT checked. d. Erase Flash is checked. e. Load File is NOT checked. f. The Modbus Serial tab is selected. (1) The COM port of the PC is selected in the pull-down.

Page 21: Operation
Operation A web browser is used to configure the QUCM. The serial ports must be configured to set the default modem dialing strings, configuration strings, baud rate, etc. Each remote slave must also be entered into the QUCM’s look-up table and associated with a particular Modbus/TCP destination index. -
Page 22: Mucm Operation
Non-Priority Write Remote Operation without an MUCM Niobrara recommends that Modbus ASCII be used to communicate across standard 10-bit dial-up modems. Modbus ASCII requires a minimum of special configuration of the modem pair. Modbus RTU or PNIM absolutely require modem configuration of 8 data bits and the modem pair must be set for no error correction, no software flow control, and no hardware flow control. -
Page 23: Web Server
Web Server Navigation Bar The left side of each page includes a set of navigation links. This list changes dynami- cally based on the current page displayed. The root links are Home, Configuration, Statistics, and Help. Home The Home link displays a page similar to figure 4-1. It gives a brief summary of the number of devices configured, the settings on the two QUCM serial ports, and the status of the modem connections. -

The Modem Init String is used to send the modem general configuration. The modem must be configured for active DCD and active DSR hang-up. Normally these are set with the &C1 and &D2 values. Consult the modem manual for more information. The default string is for a Multitech modem: AT&FX4&C1&D2&E1&E3&E14$EB1$BA0&W0 The Dial Prefix is prepended on every dial string. -
