Serial IO MKII

The Serial IO MKII is a telemetry unit targeted at railway applications.

It is suited to the following applications:

• Protocol conversion. The Serial IO MKII supports a number of protocols commonly used in the railway industry and it supports a number of different carriers. It is designed to be very flexible in converting between different protocols and mapping control/indication bits in different scenarios allowing for a solution in almost any situation.
• Remote digital input/output. The Serial IO MKII supports 32 opto-isolated digital inputs. It also has 32 relay contact closure outputs capable of driving track relays directly.
• Remote analogue level sensing. The Serial IO MKII optionally supports 8 isolated analogue inputs. These inputs can measure 4-20mA current loops, ie for track temperature sensors, they can also measure 0-60 Vdc, ie for battery voltage level monitoring. Alarm thresholds can be set to trigger bit indications, or the full reading can be retrieved.

The Serial IO MKII has the following key features:

• Protocol support. The Serial IO MKII supports the following protocols.
  • S2 protocol, master and slave. Multiple slave addresses supported.
  • Genisys protocol, master and slave. Multiple slave addresses supported.
  • Host protocol, master and slave. Multiple slave addresses supported.
  • UCE protocol, master and slave.
  • NTP protocol, client, to synchronise the internal real time clock.
• Carrier support. The Serial IO MKII supports the following carriers.
  • Asynchronous RS232, 600 to 115200 baud.
  • Synchronous RS232, 600 to 9600 baud.
  • Ethernet TCP/IP master or slave.
  • Ethernet UDP/IP master or slave.
  • VF modem with 600 ohm interface, supporting V.21, V.22, V.23, Bel103 & Bell202.
• Digital IO support. The Serial IO MKII digital IO has the following features.
  • 32 digital, opto-isolated inputs which can be driven from a large range of voltages.
  • 32 digital, relay contact closure outputs, which are capable of driving railway industry standard Q-series relays directly.
  • The digital IO connectors match, and are compatible with, the commonly used EDMI RailMaster Compact.
• Analogue IO support (optional). The Serial IO MKII analogue IO has the following features.
  • 4 isolated 12 bit analogue to digital converters (ADC) inputs.
  • Each ADC input capable of reading 0-44v (10mV resolution) and 0-20mA (5uA resolution).
  • 4 digital, relay contact closure outputs, with both normally open (NO) and normally closed (NC) contacts accessible.
  • 4 digital, opto-isolator outputs.
• All external connections are electrically isolated from each other.
• Remote monitoring, configuration and even firmware update.
• Multi-level SD card and/or remote logging with full time stamp.
• Configuration load from SD card for easy deployment.
• Low power operation, running from an 8 to 28 Vdc supply.
• New Australian design, using new technology, fully supported with customisation available.
• Regulatory Compliance Mark (RCM/C-Tick), ASNZS CISPR22/A.

Any control/indication bits can be mapped between any supported protocol and/or digital IO. Any protocol can run over any supported carrier. This makes the HASCOM Serial IO MKII well suited to resolve your protocol incompatibility issues.
