1 Product Overview The Vista Electronics LM104-P50 module provides connectivity between PC/104-based sy stems and the Echelon Local Operating Network (L ON). The module features full compliance with Echelon’s L onMark Inte roperability Guidelines, grea tly simplifying hardware a nd software integration into sy stems built around LonWorks. The MS-[...]

2 Module Setup IMPORTANT NOTE! The LM104-P50 module gets all of its electrical power through the PC/104 bus connector. The module requires +5Vdc, ±10% at 420mA. Because it was designed specifically f or the PC/104 bus, the m odule does not support any exte rnal power supply, nor is it designed to run at any other supply voltage. Operating an LM104[...]

3 Jumper Settings There are five jumper locat ions, which vary slig htly depending on which network interface option is selected. Their functions are as fol lows: JP1 SERVICE Momentarily shorting this jumper causes the Neuron c hip to broadcast its Neur on I D across the network. This jumper should normally be left open. Defaul t: OPEN JP2 RESET Mo[...]

4 JP5 IRQ SELECT This jumper selects the I RQ (Interrupt Request) level used by the LM104-P50 and the interrupt- driven driver ( LM104INT.SYS ): 1 I RQ15 2 I RQ12 3 I RQ11 4 I RQ10 5 I RQ5 6 I RQ3 Defaul t: IRQ5 Note that I RQ10, IRQ11, I RQ12 and IRQ15 are only available on 16-bit sy stems (80286-class or higher microprocessors). JP6 TRA NSM IT OU[...]

5 Softw are Driver Installation The LM104-P50 module includes two MS-DOS software drivers: one that is interrupt driven ( LM104INT.SYS ) and one that use s polling ( LM104POL.SYS ). The inte rrupt driver is used in most cases. First, copy the files on the distribution diskette to a drive and directory on the host sy stem. For the inter rupt driver,[...]

6 For example, adding the following line to the CONFIG.SYS file: DEVICE=C:LONLM104INT.SYS /D1 /P1 /Q5 installs the interrupt-driven driver using base I /O address &h1E0 and IRQ5. Adding the following line to the CONFIG.SYS file: DEVICE=C:LONLM104POL.SYS /D1 /P3 installs the polling driver at I /O address &h310. The polling driver does n[...]

7 Cable Grounding and T ermination To maintain data tr ansmission performa nce, network c abling must be termina ted cor rectly . Termination requirements vary depending on the type of cable used for network connections – shielded or unshielded twisted pair - and the ty pe of transceiver used. Cable Grounding The majority of LonWorks networks use[...]

8 The RS-485 standard further specifies that network cabling have a characteristic impedance of approximately 120 W . The use of coaxial or twinaxial ca ble is not recommende d. VI STA Electronics re commends using a high quality , low loss poly ethylene -insulated twisted pair wir e (such as Belden 9841) for optimum results, although less expensiv[...]

9 Option 5 – Power line carrier transceivers These modules are designed to be used with couplers that interface between the node and the power line. As such, the PL T-22 transceiver and the power line coupler handle any termination issues. Any standard 50 W BNC cable may be used to connect the L M105-P50 to its line coupler. Because the transmiss[...]

10 Troubleshooting • Make sure that the sy stem has power, and make sure that all voltag es are within specification. The Neuron chip does not tolerate under- or over-voltage conditions very gracefully . • Make sure tha t the driver’s comma nd-line switches ( /P# and /Q# ) match the jumper setting s on the module (JP4 and J P5, respectively )[...]
