1.3: RS232 Wiring Details n RS232 communication is capable for a distance up to 50 feet (15.2 m). The Master Port and Slave Ports 3–16 are 9-pin female RS232 ports. Use standard RS232 extension cables for all RS232 connections. n The RS232 Master Port enables the Substation Multiplexor to communicate directly with a computer or connect to an external modem. The Master Port is DCE or DTE selectable. Set the switch beneath the port to: • DTE when using a modem (internal or external).
1.4: RS485 Wiring Details n RS485 communication allows multiple devices to communicate on a bus. The Substation Multiplexor’s Slave Port 1 and Port 2 are 2-wire RS485 terminals, viable for a distance of up to 4000 feet (1219 m). • Use a shielded, twisted pair cable, AWG 22 (0.33 square mm) or larger. • Establish point-to-point configurations for each device on a RS485 bus: Connect (+) terminals to (+) terminals; connect (-) terminals to (-) terminals.
Correct Connection eElectro Industries/GaugeTech Doc # E113-7-03-1.
Incorrect Connection: “T” “Tee” Connection Incorrect! The three wires connected in a “T” shape on both the (+) and (-) terminals will cause interference problems. RS485 Port Incorrect Connection: “Star” “Star” Connection Incorrect! The three wires connected in a “Star” shape on both the (+) and (-) terminals will cause interference problems.

Chapter 2 Modem Option Operation 2.1: Overview n Substation Multiplexor with Modem Option provides a dependable solution for substation telecommunication applications. This unit multiplexes 16 serial ports to one master port, providing the ability to communicate and switch between multiple serial devices. This switch uses Modem Manager Technology that allows the internal or an external modem to communicate without any need to specifically program the modem for a particular device.
• Relay Option: Once powered up, the relay will stay energized unless there is a problem. One of the following conditions will de-energize the relay: 1. Checksum Mismatch on the unit’s run time code. 2. Internal Modem is not functioning properly. 3. Loss of power in the unit. • Power On and Off Switch: With this switch, you can shut down without unplugging the unit.
2.2: Using Windows ®® HyperTerminal with the Substation Multiplexor n Windows® HyperTerminal is just one type of communications program you may use to configure the Substation Multiplexor. 1. Refer to Chapter 1 for installation and communication instructions. 2. From the Windows® Start Menu, select Programs, Accessories, Communications, HyperTerminal. 3. Double-click on the HYPERTRM.exe icon. The following screen appears: 4. Type a name for the location, such as “Multiplexor”, and choose an icon.
5. Make a selection from the “Connect Using” menu. Different screens will appear, depending on your selection. All of the screens will take you to the Multiplexor Properties and ASCII Setup screens: To make a modem connection: Enter the Country code, Area Code and Phone Number. In the “Connect using” field, select the type of modem connected to your computer. Proceed to step 6.
• Click on the Modify button; click on the Settings tab. The following screen appears. 7. In the “Emulation” field, select ANSI from the pull-down menu. 8. Click on the ASCII Setup button.

The ASCII Setup screen should look like the following: 9. Click OK. You are now ready to dial the Substation Multiplexor. Proceed to section 2.5.
2.3: Using EIG’s Futura Communicator with the Substation Multiplexor n Put the Substation Multiplexor into Command Mode first so a data string can be recognized by the Substation Multiplexor. The data string tells the Substation Multiplexor what Slave Port you would like to use and then instructs it to enter Throughput Mode so data transmission may begin. 1. Before connecting to the Substation Multiplexor, click on Futura Communicator’s Phone Book button to call up the Phone Book Screen: 2.
2.4: Using EIG’s Nexus Communicator with the Substation Multiplexor n Put the Substation Multiplexor into Command Mode first so a data string can be recognized by the Substation Multiplexor. The data string tells the Substation Multiplexor what Slave Port to use and then instructs it to enter Throughput Mode so data transmission may begin. v Note: Be sure to configure the Nexus 1250/1252 Monitor port connected to the Multiplexor to speak Modbus ASCII. See the Nexus Communicator User Manual for details.
2.5: Command Mode n To enter Command Mode from Throughput Mode, send the following escape string: • • [2-second pause]%%%[2-second pause] (or $$$,###,@@@,!!!) After the last 2-second pause, type H[Enter]. v Note: The “%” keystrokes must be made less than two seconds apart. n BE SURE TO USE ALL CAPITAL LETTERS WHEN SENDING COMMANDS TO THE MULTIPLEXOR; THE UNIT ONLY RECOGNIZES CAPITAL LETTERS. n To begin, type H[Enter].

2.12: Go to Throughput Mode n The GT command puts the Substation Multiplexor in Throughput Mode, allowing the computer to communicate with the device(s) connected to the selected Multiplexor Slave Port. The Substation Multiplexor will not accept commands in Throughput Mode. To return to Command Mode send the escape string detailed in section 2.5. • Type GT[Enter] 2.13: Go to Boot Mode n Boot Mode is used for flash upgrading ONLY, as additional features become available.
n Command Mode Password Protection • Type PWCE[Enter] to enable the password. For this example, 123 will be the password. • Type W123[Enter] (W[Enter]) • Type W123[Enter] again. OK will appear. • Type PW[Enter] to verify the enabled Command Mode Password. Reset the unit or go to Throughput Mode and come back to Command Mode. Type any command; it will be password protected. Type the password to use all commands. • n Type W123. OK will appear. All commands are available.
2.16: Fail Safe Relay for Internal Modem n Substation Multiplexor will check the Internal Modem during power-up and after reset of the unit. If the Fail Safe Relay is enabled, the unit will be de-energized if a problem is found in the Internal Modem. • Type GRE[Enter] - Enable Modem Detect Relay. The following screen appears: • Type GRD[Enter] - Disable Modem Detect Relay to disable the relay. -----------------------------------------------------SUBSTATION MULTIPLEXOR BOOT VERSION : V1.
