Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Overview 2.1 Quick Start This Quick start chart summarizes the basic setup and operation steps: 3 Overview The Kramer PL-8 is a high performance relay controller. It can connect to up to eight devices. The PL-8 is intended to be used for the simplified and centralized control of room functions (such as lighting, closing blinds, and so on).
Your PL-8 Low Voltage Relay Controller • Can be controlled by Kramer SummitView™ control units such as the SV-551, RC-62 and RC-63 • Can be upgraded via RS-232 • Is housed in a Kramer TOOLS enclosure and is 12V DC fed Achieving the best performance means: • Connecting only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables) • Avoiding interference from neighboring electrical ap

Firmware Upgrade 6 Firmware Upgrade The PL-8 firmware is located in FLASH memory, which lets you upgrade to the latest Kramer firmware version in minutes! The process involves: • Downloading from the Internet (see section 6.1) • Connecting the PC to the RS-232 port (see section 6.2) • Upgrading Firmware (see section 6.3) 6.1 Downloading from the Internet You can download the up-to-date file 1 from the Internet. To do so: 1. Go to our Web site at www.kramerelectronics.
Firmware Upgrade Figure 6: Splash Screen 2. After a few seconds, the Splash screen is replaced by the “Atmel – Flip” window: Figure 7: Atmel – Flip Window 3. Press the keyboard shortcut key F2 (or select the “Select” command from the Device menu, or press the integrated circuit icon in the upper right corner of the window).
Firmware Upgrade Figure 8: Device Selection Window 4. Click the button next to the name of the device and select from the list: AT89C51RD2: AT89C51RD2 T89C51RD2 Figure 9: Device Selection window 5. Click OK and select “Load Hex” from the File menu.
Firmware Upgrade Figure 10: Loading the Hex 6. The Open File window opens. Select the correct HEX file that contains the updated version of the firmware for PL-8 (for example 44M_V1p2.hex) and click Open. 7. Press the keyboard shortcut key F3 (or select the “Communication / RS232” command from the Settings menu, or press the keys: Alt SCR). The “RS232” window appears.
Firmware Upgrade 8. Click Connect. In the “Atmel – Flip” window, in the Operations Flow column, the Run button is active, and the name of the chip appears as the name of the third column: AT89C51RD2. Verify that in the Buffer Information column, the “HEX File: PL8.hex” appears. Figure 12: Atmel – Flip Window (Connected) 9. Click Run. After each stage of the operation is completed, the check-box for that 1 stage becomes colored green .
Kramer Protocol15F Figure 13: Atmel – Flip Window (Operation Completed) 10. Close the “Atmel – Flip” window. 11. Disconnect the power on the PL-8. 12. If required, disconnect the RS-232 terminal block connector on the PL-8 unit from the Null-modem adapter. 13. Slide the underside PROGRAM switch back to normal. 14. Connect the power to the PL-8. 7 Kramer Protocol 1 By default, the PL-8 is set to protocol 3000 (see section 7.1) but is also compatible with Kramer’s Protocol 2000 (see section 7.2).

Kramer Protocol 7.2 PL-8 Commands in Protocol 3000 This RS-232/RS-485 communication protocol 1 lets you control the machine from any standard terminal software (for example, Windows® HyperTerminal Application) and uses a data rate of 115200 baud, with no parity, 8 data bits, and 1 stop bit. This section describes all commands sent to the PL-8. For an explanation of the syntax and use of Protocol 3000, see section 7.2.4. 7.2.
Kramer Protocol Note: * Command required Admin login. * New ID will done only after device resetting * Connecting 2 devices with same ID over one KNET network could cause unexpected behavior. 7.3 Protocol 3000 Syntax Protocol 3000 is used to control the PL-8 via an RS-232 connection using a PC, touch screen, other serial controller or RC type controller. 7.3.1 Host Message Format Start Address (optional) Body Delimiter # Destination_id@ Message CR 7.3.1.
Kramer Protocol 7.3.2 Command Terms Command A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-'). Command and parameters must be separated by at least one space. Parameters A sequence of alphameric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special characters for specific commands). Parameters are separated by commas. Message string Every command entered as part of a message string begins with a message starting character and ends with a message closing character.
Technical Specifications 7.3.4 Command Forms Some commands have short name syntax in addition to long name syntax to allow faster typing. The response is always in long syntax. 7.3.5 Command Chaining Multiple commands can be chained in the same string. Each command is delimited by a pipe character ( '|' ). When chaining commands, enter the message starting character and the message closing character only once, at the beginning of the string and at the end.
