Electro Standards Laboratories, Inc. (401) 943-1164 www.electrostandards.com - pg 4 - Pub. 5820-01 INTRODUCTION The PathWay® Model 7105 50-Pin Telco to RJ11 Switch with RS-232 Remote allows the user the capability for the Telco 50-pin, 25 pairs to be switched 2 wires at a time, to the RJ11 connector 1 set at a time with remote access functionality. The Model 7105 is enclosed in a 2U, full rack size, all metal black chassis designed to provide EMI/RFI shielding and fit in a standard 19” rack. The switch may be controlled locally by manually operating the front panel pushbutton or remotely from the DB9 Remote Control port located on the rear of the unit. The DB9 Remote port provides control through RS-232 Serial Commands and allows the user to both control and monitor the switch position remotely. The front panel LED display indicates the switch position and unit power status. Features: • The switch ports are transparent to all data. • Pins 3 and 4 of the RJ11 interface are switched via a break- before-make electromechanical relays. • The unit maintains last set position on power loss and continues to pass data. • Independent control of 25 pairs of 50-Pin Telco switched 2 wires at a time to the RJ11 connector 1 set at a time. • Front panel pushbutton control. • Off-Line position is obtained solely via the RS232 Remote commands. • When in Off-Line position, no channels will be connected and front panel LED’s are turned off. • Once in Off-Line position, the user can return to On-Line position via RS232 commands or the front panel pushbutton. • Remote RS-232 ASCII commands that allow the user to control switch position, including Off-Line position, lock and unlock front panel pushbuttons, and obtain switch status. • Front panel LED’s display present position and power status.

Electro Standards Laboratories, Inc. (401) 943-1164 www.electrostandards.com - pg 6 - Pub. 5820-01 Serial Remote Port Pinout Connect the Remote DB9 (F) Serial Remote Control port located on the rear of the Model 7105 to a serial port located on the back of a computer if Remote Control is required. The name, direction, and pin designation of the signals supported on the Remote Control port are as indicated in Table 1. Remote control port cable supplied on request, call Electro Standards Laboratories phone #: (401) 943-1164. SIGNAL NAME PIN # DIRECTION TRANSMIT DATA (TD) 3 INPUT RECEIVE DATA (RD) 2 OUTPUT SIGNAL GND (SD) 5 -------------- Table 1: Serial Remote Port Pinout DTE and DCE The individual signals on a serial port are unidirectional and when connecting two devices the outputs of one device must be connected to the inputs of the other. Devices are divided into two categories “Data Terminal Equipment” (DTE) and “Data Circuit-terminating Equipment” (DCE). A line that is an output on a DTE device is an input on a DCE device and vice versa, so a DCE device can be connected to a DTE device with a straight wired cable. Conventionally, computers and terminals are DTE, while modems and peripherals are DCE. In this circumstance, the Model 7105 is a DCE device. Computers are typically DTE devices. USB Driver (for USB to DB9 Serial Converter Cables Only) If only USB ports are available on the computer or if a USB port is chosen to be used for any reason, a USB to DB9 serial converter cable will be needed. This cable can be provided by ESL under part number 528693. If a converter cable is being used for control and the computer is not communicating with the unit, download and install the USB driver from http://www.ftdichip.com/Drivers/VCP.htm. You need to download and install the appropriate latest driver version for the operating system and processor architecture in use on the computer. Please note Microsoft has ended support for Windows XP and Windows Vista. The latest drivers are not Microsoft certified for those operating systems, but the drivers will still work.

Electro Standards Laboratories, Inc. (401) 943-1164 www.electrostandards.com - pg 9 - Pub. 5820-01 Remote Control Setup Remote switching of the unit is accomplished through the RS-232 (DB9 Female) Serial Remote Control port located on the rear of the Model 7105. This port may be connected to the RS-232 port on a computer or any other device capable of sending ASCII characters. (See installation section for cable information.) Use a Windows-compatible terminal emulation software, such as Hyperterminal, with the following configuration to connect to the Model 7105: Parameter Value Baud rate 9600 Data bits 8 Parity None Stop bits 1 Flow control None Table 3: Serial Communication Configuration Remote Control Commands All commands are ASCII CONTROL commands. A CONTROL command is created by pressing and holding the [CTRL] key and the designated character key simultaneously. For example, to create the CTRL-A command, simply press the [CTRL] and [A] keys on the keyboard simultaneously then release both. Do not press the Enter key at the end of a command. See Table 3 for details. All responses are terminated with a carriage return (‘\r’) followed by a new line feed (‘\n’). A note to those programming their own systems to control this switch automatically: The ASCII Control commands are represented as the decimal equivalent of the numerical position of that letter in the alphabet, which can then be translated to hex. For example, CTRL-A translates to ‘1’ in decimal or 0x01 in hex, since A is the 1st letter of the alphabet. CTRL-V, on the other hand, translates to ‘22’ in decimal, and 0x16 in hex, since it is the 22nd letter of the alphabet.

Switch Position on Power Down If power to the Model 7105 is lost, the switch will maintain its present position and continue to pass data. Upon power restore, the unit will remain in the position it was in at power down.

Electro Standards Laboratories, Inc. (401) 943-1164 www.electrostandards.com - pg 11 - Pub. 5820-01 TROUBLESHOOTING Described below are some common troubleshooting steps and solutions. If following the troubleshooting guide does not solve the problem, please contact Technical Support for further assistance. Switching Issues Pressing and releasing the front panel pushbutton does not cause the unit to switch. • Check that the unit is properly powered and that the front panel LED’s indicate the present position. • If all LED’s light up while the pushbutton is held, front panel operation is locked out and must be unlocked through the Remote. • For the 50-Pin Telco to RJ11 Custom Pins Switched Chart, see Table 2 on page 7. Commanding the unit remotely to switch does not cause the unit to switch. • Check that the Remote Connection is still active. Check if any response to commands is received. If no response is received, troubleshoot the Remote Connection. Remote Issues The switch does not accept Remote commands. • Check that the physical connections and pinouts are correct. Conventionally, PC serial ports are configured as DTE devices, meaning that a straight thru cable should be used, not a null modem cable. • Check that the unit is powered on and ready to operate. • Ensure that the terminal software is configured with the correct parameters. See Table 3 on page 9. The switch accepts commands and can switch, but no response is received. • Check that the transmit line of the unit is connected to the receive line of the communicating device. See Table 1 on page 6 for pinout information. The switch does not operate correctly by Remote and responds with garbled text. • Ensure that the correct baud rate and other serial communication parameters are correct. See Table 3 on page 9.

Electro Standards Laboratories, Inc. (401) 943-1164 www.electrostandards.com - pg 12 - Pub. 5820-01 The commands/responses have changed and no longer work with existing scripts/software. • There is a compatibility mode to support this built into the firmware.
