+===== - OVERVIEW =====
 ==== - Introduction ====
 The MTB-etc (enhance temperature control) is a new class of instrument that extends the temperature range for K thermocouples to 1100.0°C (2012.0°F) and the J thermocouples to 860°C (1150°F).   All MTB-etc units are factory calibrated to +/- 1.0°C accuracy.  Floating point displayed values are shown in tenths of a degree.  See section 4.3 for more information how to setup the MTB-etc and the thermocouples to ensure the highest degree of accuracy.  The MTB-etc is an RS-485, MODBUS RTU slave board capable of reading 33 channels. The first 30 channels can be any combination of digital inputs (N/O or N/C), thermocouples (J or K), pressure inputs, 4-20mA inputs, or read any sensor within the range of 0-5VDC. Channels 31 and 32 can only be used for digital inputs (N/O or N/C). There is also a pickup input. Additionally, there are 8 digital outputs which are capable of sinking 60V at 500mA. Each could drive a relay, horn, or other related device. There are also two 4-20mA outputs. All the outputs are directly controlled by Modbus commands. The Modbus Terminal Board is CSA-certified for CLASS I, DIVISION 2, GROUPS C and D areas, when mounted in a suitable enclosure.
