SDTest

Introduction

The SDTEST IOCs allow us to set up communications with an arbitrary device on-the-fly. This often happens if an instrument acquires a bit of equipment to achieve a short term goal. We should try and ensure that if a device is to be used long-term that we find out about it early enough to provide a dedicated IOC, or deliver it as soon as practical.

Macros

Each SDTest IOC supports communication with 8 separate devices on 8 ports. Macros should be suffixed by the device number in the range 1 to 8 inclusive (e.g. PORT1):

• PORT: Communications port (e.g. COM1)
• BAUD: Baud rate (default: 9600)
• BITS: Message bits (default: 8)
• PARITY: Message parity (default: none)
• STOP: Number of stop bits (default: 1)
• CLOCAL: Output flow control using DSR signal (Y/N, default: Y)
• CRTSCTS: Hardware flow control (Y/N, default: N)
• IXON: Software flow control for output (Y/N, default: N)
• IXOFF: Software flow control for input (Y/N, default: N)
• OEOS: Output terminator (default: \r\n)
• IEOS: Input terminator (default: \r\n)
• NAME: Name of the device
• SCAN: Scan rate
• GETOUT: Command for getting the readback
• GETIN: Format of the readback
• SETOUTA: Command for setpoint
• SETOUTB: Secondary setpoint value
• SETOUTC: Tertiary setpoint value
• SETIN: Format of the setpoint
• INITOUT: Initialisation command
• INITIN: Format of init response
• INITP: Send an initialisation command (default: NO)
• PROTO: Path to custom protocol file, (default: SDTEST-default.proto)
