Pickering Interfaces strives to fulfil all relevant environmental laws and regulations and reduce wastes and releases to the environment. Pickering Interfaces aims to design and operate products in a way that protects the environment and the health and safety of its employees, customers and the public. Pickering Interfaces endeavours to develop and manufacture products that can be produced, distributed, used and recycled, or disposed of, in a safe and environmentally friendly manner.
SECTION 1 - INTRODUCTION Pickering Interfaces Series 1000 SIM Reed Relay Cards offer a choice of switching configurations using low cost industry standard SIM connectors. They free the designer from the detail of routing complex switching circuits, you may select from a wide range of cards using the built in RS-232 and I C interfaces.
SECTION 1 - INTRODUCTION pickering Accessories (Carrier Cards and Control Interfaces) Carrier cards are available that support either one or three SIM cards. For applications where more than one SIM relay card is supported, each card can be I C controlled and an optional RS232 to I converter used to provide overall RS232 control.

SECTION 3 - INSTALLATION AND OPERATION pickering SECTION 3 - INSTALLATION & OPERATION WARNING - DANGER OF ELECTRIC SHOCK BEFORE REMOVING THE MODULE FROM THE MOTHER BOARD ENSURE THAT ALL CONNECTIONS TO THE MODULE ARE REMOVED CAUTION Electrostatic discharge can damage the components on the module. To avoid such damage in handling the board, touch the anti-static bag to a metal part of the chassis before removing the board from the bag.

SECTION 3 - INSTALLATION AND OPERATION pickering Constructing Large Switching Networks with RS-232 or I The SIM Relay Card may be operated by RS-232 or I C in the ways shown in the diagrams below. For a description and wiring diagram for interconnecting multiple SIMRC modules in a daisy-chain configuration, please refer to Section 6.

SECTION 4 - PROGRAMMING pickering C-bus Operation The protocol for I C-bus operation is modelled on IEEE488.2, which is a well-proven and reliable standard. The use of command and query mnemonics, and the facility for obtaining extended response data from the unit are features intended to allow it’s use in more complex devices.

SECTION 4 - PROGRAMMING pickering The number of data bytes required by the SB command depends on the number of outputs available on the particular module: a 32-output module requires 4 bytes, a 16-output module requires 2 bytes. Data bytes received are interpreted in descending order of significance;...
SECTION 4 - PROGRAMMING pickering RS-232 Operation Communication Standard and Handshaking Communication settings are fixed at 9600 baud, 8N1. Neither hardware (CTS/RTS) nor software (XON/XOFF) handshaking is employed bySIMRCs. Data input is line buffered, full duplex, supporting backspace-and-delete. Input line terminator is <CR>; output lines are terminated with <CR + LF>.

SECTION 4 - PROGRAMMING pickering TY query: Module identification string, eg. “SW160001” “SW” = module type “16” = module dimension (X) “00” = module dimension (Y), or special features code “01” = firmware release number WH query: Module introductory message, including firmware revision and I C address setting.

SECTION 4 - PROGRAMMING pickering Programming examples A good way to become familiar with operation is to use a serial terminal or Terminal Emulator program (such as Windows HyperTerminal) to communicate with a unit via it’s RS-232 port. 16-channel switch module - get type info (typical response “SW160001”)
C-bus operations and can be used for communication with any I C device. A further set of commands are specific to Pickering SIM Relay Cards. RS-232 operation is fixed at 9600 baud, 8N1; neither hardware (eg. CTS/RTS) or software (XON/XOFF) handshaking is supported.

SECTION 4 - PROGRAMMING pickering Typical SIMRC operating times Single switch operation: 25ms approx. Programmatic Operation All commands related to I C-bus activity generate a single-line response (either “OK” or a data value, or an error message). The converter can therefore be operated programmatically using the following handshake protocol:...
SECTION 5 - PIN OUTS pickering C/RS232 Connector The SIM Relay Card has a configurable I C/RS-232 port (9600 baud, 8 bit, no parity, no handshaking). This is provided on a 4 pin Molex type connector as shown in Figure 5.3. (a jumper on the PCB selects RS-232 or I C use for this port see Figure 5.4).

SECTION 6 - GENERAL DESCRIPTION pickering Daisy-Chaining Modules The I C ports of the SIMRC modules can be daisy-chained together to allow multiple cards to be programmed by one host controller. To do this the cards should be set with different addresses and the 72-pin connector wired as shown in Figure 6.2.
Single SIM Small Outline Carrier Card Pickering Interfaces have produced a small PCB to allow users to work with SIMRC cards - product code 1091-001. It comprises a SIM Socket fitted to a PCB with terminals suitable for solder connection. Two holes are provided for mounting the PCB, as shown in Figure 6.3.
