Quick Start

TheSRM6200E-SLC comes pre-configuredforyour application (unlessotherwiserequested). In mostcases,configuration

settingsare notrequired.

Although each modem is tested before shipment, it is recommended that a bench test be done before the modem is

installed in its application.

In all applications, there is a master modem and one or more remotes. Some applications may also have one or more

repeaters. This “Quick Start” will assume that there is a repeater in the system. If there is not, ignore the parts that talk

aboutrepeaters, asthe remote modems should operatethe samewith or withoutrepeaters.

TheSRM6200E-SLCisavailable in threedifferent powerconfigurations:

• SRM6200E-SLC is a 12VDC powered device that is designed to take 12VDC in on the barrel jack on the front

panel.

•SRM6200E-SLC/BPis a24VDCpowered devicethat receives powerdirectly fromthe backplane anddoes not

need a separate power supply. Be sure that your 1746 chassis has a large enough supply — Data-Linc Group

recommends the use of the P-4 power supply chassis (a wall transformer power supply has been included for

bench testing purposes).

• SRM6200E-SLC/24Vis a24VDC powered devicethat isdesigned totake 24VDC inon theremovable screw

terminal connector on the front panel (please note the polarity: positive side marked “+” on the top if you are

supplying your own power).

Locate the modem labeled “Master” and connect its power supply to an appropriate 120VAC power source, then connect it

to the modem. The “P” LED should come on and stay on

Note: on all modems, the “RF Link” LED will come on for the first few seconds after power up.

Next, locate the modem(s) labeled “Repeater” and connect to power. The LED “P” and “RF Link” should come on and stay

on. Now locate the modem(s) labeled “Remote” and connect to power. The LED “P” and “RF Link” should come on and stay

on.The modems are now ready to carry Ethernet data.

Connectthe “Master” and“Remote” (or“Repeater/Remote”if yournetworkhas one)to the Ethernetequipment that hasbeen

pretestedfor operation. Thedevicehas beendesignedwith a crossoverswitch.The crossoverfunctioninterchanges the

transmitand receivepairsremoving theneedfor acrossover cable incertain situations.

The SRM6200E-SLC crossover switch has been factory set in the crossover position. If the system is connected and the

LAN link LED is not lit, the crossover switch (SW3- Diagram 3, pg. 24) may need to be moved to the straight through

position.

DATA-LINC GROUP

SRM6200E-SLCUser’sGuide

rev 3/29/04

Tochange thecrossover switch removethe SRM6200E-SLC fromtheAllen-BradleySLC500 Slot Rack.Underthe edgeof

the enclosure is a black and silver slide switch (S3- Diagram 3, page 24). If connecting to an Ethernet hub, the crossover

switch should be set in the straight through (left) position. If connecting to a PC, PLC or most other Ethernet interface

equippeddevices, thecrossover switch shouldbe setinthe crossover(right) position.

Note: TheSRM6200E-SLC willnot support“Peer toPeer” communications. The equipment thatis attachedto the

SRM6200E-SLCmust becapableof operatingin a “Master(host) toRemote” network

It is recommended that a “Ping” test be done at this point. This can be done in either direction, but remember that only a

“Master to Remote” or “Remote to Master” connection can be established through the modems.Also note that because of

the MAC filtering done by the modems, if you take a piece of Ethernet equipment on one side of the SRM6200E-SLC

networkand move it to the other sideof saidnetwork, youmust power down both the “Master” and the effected“Remote” in

order to re-establish connectivity through the modems. If powering down the modem is not practical to the applications, the

modems will rebuild the MAC filter table in approximately six minutes and communications should return. Once a successful

“Ping” test has been done, the modems are ready for communication. If the “Ping” test was not successful, please refer to

the trouble shooting section of this manual or contact Data-Linc Group tech support for assistance.

Configuration

Inmost cases,the SRM6200E-SLCcomes pre-configured fromthe factory. However, itmay sometimes be necessary to

changethe configuration.Most parameters arechanged inthe radiosection of themodem althoughthere are a few settings

that are set using switches. If you are not sure if you need to change the configuration of the SRM6200E-SLC, you probably

don’t.Please contact Data-LincGroup for furtherinformation if youare unsure aboutyour configuration.

Switch Settings

To access the switches, remove the modem from the SLC Rack. The switch bank (SW1-Diagram 3, pg. 24) is located in the

center of the large PCB.

Note: Leave switch positions 4, 5 and 6 at factory setting of off unless otherwise directed by Data-Linc Group.

Changingthese switches requiresaradio parameterschange.

MAC Filtering Function

Alldevices capableof generating Ethernet traffichave aMAC (MediumAccess Control)address. This address is usedin the

communicationsof Ethernetdata.

The SRM6200E-SLC is factory set to perform MAC level filtering. This means that it learns all the MAC addresses from the

LAN it is connected to, and only forwards data packets across the radio links which are destined for addresses located

across the radio link. The MAC filtering function is enabled by setting switch (SW2-Diagram 3, pg.24) to the on position.

The MAC address table can store up to 10,000 addresses. Each entry to the table has a lifetime of six minutes after which

the address is deleted. This dynamic table building allows for the possibility of stations being removed from the LAN. The net

result of this filtering functionality is the reduction of unnecessary network traffic across the radio link.

Note: ManyEthernet networks have data packets that arenot coveredby theMAC filterfunction (broadcastpackets

forexample). These packetscan occupy tremendousamount of thenetwork’s bandwidth andoverwhelm the

SRM6200E-SLCsection ofthe network. Ifthe SRM6200E-SLC’sare goingto be installedwhere theyare linked to

anopen network(on officenetwork, etc.),a properlyconfigured routeror switchshould beinstalled toprotect the

modemsfrom excessivedata traffic. Ifyou areunsure aboutyour network, pleaseconsult withyour network

administrator.

19.2Kbaud, 8 data bits, no parity and one stop bit. With the modem connected to the PC running the terminal program,

pressthe Configurebutton. While anyterminal programwill work, examplesfor thismanual were generatedusing the

MicrosoftWindows2000application “HyperTerminal.”

Note: Whenusing HyperTerminal, set Handshakingto noneand usea standard straight throughcable. Ifyou are

using something other than HyperTerminal, it may be necessary to use a cable that has pins 4 and 6 connected

togetheron themodemside ofthecable. ContactData-Linc for furtherinformation.

Main Menu Option (0): Set Operation Mode

When item (0) is selected, the Operation Mode Menu appears as shown in figure 2. The Operation Mode option is used to

designatethe methodin which theparticular SRM6200E-SLCwill be used.The SRM6200E-SLCoperates in amaster to

remote configuration; therefore, any radio modems that are intended to operate together must be set up as such. In a point-

to-point setup, either the Master or Remote may be used on either end of the communications link. One consideration when

setting up the radio modems is that a number of parameters are controlled by the settings in the Master; therefore, you may

wish to deploy the Master on the communications end where you will have easier access to the radio modem.

Figure 2: Mode Menu

Shownbelow are examplesettings. Pleasereferto suppliedconfigurationsheets foryour modem’s configuration.

(0) Point-to-point Master

TheSRM6200E-SLC operates ina master/remote configuration.When designatedasa masterinpoint-to-point mode,

the radio modem will call any or all remotes it is instructed to call in the call book. The Master determines the settings

usedfor allRadio Transmission Characteristics(except power),regardless ofthe settings inthe remotesand/or

repeaters.

(1) Point-to-Point Remote

When set up as a point-to-point remote, an SRM6200E-SLC will communicate with any master in its call book, either

directly or through one or two repeaters. When functioning as a remote, the Entry to Call feature in the radio modem’s

call book (Figure 3) is not operational. The remote will communicate with any master on the list that calls.

(2) Point-to-Multi-Point Master

The SRM6200E-SLC may be set to run in multi-point mode, which allows one master to simultaneously be in

communicationwith numerousremotes.Apoint-to-multi-point master willcommunicate onlywith other radiomodems

designatedaspoint-to-multi-point remotesorpoint-to-multi-point repeaters.

(3) Point-to-Multi-Point Remote

Setting (3) allows the radio modem to operate as a remote in a multi-point network.
