Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A 1.0 INTRODUCTION Thank you for purchasing an SRX Expandable Routing Switch. Quintech’s SRX series switches are based on the same technology as our popular SRM Series Modular Programmable RF Switches. They were developed to address the increasing need for expandable RF switching in telecommunication network signal processing centers and are equally suitable for audio/video, baseband, data, IF, and RF switching requirements.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A 2.0 MODULES Two types of modules are used to configure an SRX system: an MCP 128 (8x1) controller and a 16x1 switching module. Every SRX system is comprised of one controller and 1 or more switching modules. A minimal SRX switching system consists of a single controller and one switching module.

Each module is 1RU (1.75”) in height and is easily installed in any standard rack, using four screws.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A If you are using a computer to control the SRX, you can use a direct serial connection or a 10BaseT Ethernet connection. For serial control, connect a serial cable (RS-232 or RS-422/485) from the computer to the 9-pin SERIAL port on the rear panel of the controller module. The connector is shared for both RS-232 and RS-422/485. No NULL MODEM or crossover cable is needed when connecting an RS-232 cable.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A 4.0 OPERATION The SRX Series Matrix Switching System can be controlled locally via the front panel keypad/LCD screen or remotely through the serial port or Ethernet port on the rear panel using the software provided with all standard SRX modules. If desired, all three methods can be used simultaneously. Firmware updates can be downloaded via the Serial and Ethernet ports.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A To view the status of an output or input channel, type in the output/input number or use the scroll arrows to scroll up or down respectively. One, two, or three digits may be typed. For example, Output 1 may be represented as 1, 01, or 001. The number will be entered automatically about 1 second after no more digits are entered.

Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A 4.2.2.2 Etheret Configuration The Ethernet configuration screen controls the static IP configuration for Telnet (port 23) and the auxiliary QEC port. The QEC port allows you to send STX/ETX formatted packets to the SRX. Whenever “Ethernet” is selected in the Interface Options menu, you will be able to set the IP configuration (option 1), enable/disable the DHCP server (option 2), and configure the Ethernet port (option 3).
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A DHCP The DHCP Screen enables you to enable or disable the use of a DHCP server for obtaining IP address information. When set to ON, the IP address of the SRX is dynamically assigned by the DHCP server. Note that the IP address assigned in this manner will override any IP address that may have been specified via the IP Configuration Screen.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A Password The Password Screen enables you to reset the QEC port access password to the Quintechspecified default. Press F4 to exit or F1 to reset the password. Reset password F1=Enter to “Quintech” F4=Exit Password Screen 4.3 Ethernet Control The SRX has a 10BaseT Ethernet port and supports TCP/IP. All commands are sent to the configured IP address and port.
Quintech Electronics and Communications Inc. SRX Series Switching System 4.4 Rev. A Serial Port Control The SRX has a standard DB-9 serial input connector on the back panel. This connector is shared for both RS-232 and RS-422/485 interfaces. The serial port parameters are fixed at 9600 baud, 8 data bits, no parity, and 1 stop bit (8N1). No NULL MODEM or crossover cable is required on this port. The command protocol for controlling the switch is provided in Appendix A.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A 5.0 Troubleshooting This section has been written to help eliminate operator error. It does not describe how to repair damaged equipment. The control connections are properly connected, yet the system is not communicating. It is possible that the system needs to be biased or terminated. Refer to Appendix A. The front panel LED/LCD is not lit. This indicates the unit is not receiving power.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A The SRX will not respond to protocol commands on the Serial Port. Make sure that the address in the commands being sent matches the serial address set for the SRX. Check that the serial interface mode (RS-232 or RS-485) is correct and that the serial cable from the computer is connected to the CONTROL IN DB-9 connector port on the back panel.
Quintech Electronics and Communications Inc. SRX Series Switching System Rev. A I am a qualified technician and would like to try to fix a problem myself. A warranty covers all units. QEC, or a representative of QEC, should make the required repairs. Removing any part of the chassis will void the warranty. Additionally, attempting to repair a unit could be dangerous. There is a lot of crosstalk between the signals. It may be necessary to “balance” your signal levels.

Quintech Electronics and Communications Inc. SRX Series Protocol Protocol Version 2.15 1 Quintech SRX Series Protocol v2.15 8/18/2003 Rev A This document specifies a common command protocol that can be used to control a Quintech SRX controller from a computer. Command Summary This list gives the commands defined in Protocol 2.15. C Check Change Flag / Unit Status. This flag will be set if a crosspoint has been changed since the last polling or if any alarms are present. E Ethernet.
Quintech Electronics and Communications Inc. SRX Series Protocol Protocol Version 2.15 2 Protocol Message Structure Commands packets can be sent over the Ethernet and serial ports (if available) and use a standard STX/ETX protocol wrapper. Each packet includes a header byte, a two-byte address field, a command byte, necessary data bytes, end byte, and a checksum byte. The bytes are transmitted using an 8-bit word, with 1 stop bit and no parity.
Quintech Electronics and Communications Inc. SRX Series Protocol Protocol Version 2.15 3 Address FF is a serial broadcast address. Any unit will respond to a command with an address of FF regardless of the actual serial address set for the unit. Commands being sent to units over Ethernet must contain an address of FF for proper operation. Otherwise a nonmatching serial address could cause the command to be rejected even though the IP address was correct.
Quintech Electronics and Communications Inc. SRX Series Protocol Protocol Version 2.15 4 Command Descriptions C: Check Change Flag/Unit Status The change flag tells the user if any crosspoint changes are in the queue. The queue will store up to eight changes made from the local front panel keypad control. This command can be sent periodically to check if any local changes have been made or if any alarms have occurred. The change flag is cleared only when the queue is empty.
