is the left-most pin on the TB. TB pins are numbered in
sequential order, beginning with pin 1.
8.6 Reset
Upon module reset, all power outputs switch to 1.25 volts out.
A 2612 module will experience a module reset in response to
any of the following conditions:
• Module power-up.
• Watchdog time-out due to soft or hard fault.
• SoftReset or HardReset action request from the client.
• Communication time-out, which will occur if the client
fails to communicate with the 2612 module within a
programmable communication watchdog interval.
8.7 Actions
This section describes the programmable actions that are
supported exclusively by 2612 modules. These actions may be
employed, in any sequence or combination, in MCmd action
lists. In addition to the actions listed here, the 2612 module
also supports all of the common actions that are universally
supported by all IOMs.
Note: Model 2612 has a maximum MRsp size of 26 bytes.
8.7.1 SetMode
Function Programs the conversion mode of one analog
input channel.
Opcode 0x00
Command (Chan),(Mode<7:0>),(Mode<15:8>),
(Mode<23:16>),(Mode<31:24>)
Mode: bits 31 to 20 specify the oversample ratio
(OSR), as shown in the following table. See
Section 8.2.1 for details. Bit 19 specifies the
speed multiplier mode. Bits 18 to 0 must be set to
zero.
Response none
8.7.2 GetInputs
Function Returns the digitized values of all analog input
channels.
Opcode 0x01
Command none

1,8 Shld This may be connected to a
cable shield, but the shield
conductor must be
unconnected at the remote
end of the cable in order to
avoid ground loops.
