Reset and Registers

Following power-on or a *RST command, the registers are put into the following states:

–The Manufacturer ID and Device ID Registers remain unaffected.

–The Channel Mode Register (base + 1A16) is set to voltage output for all channels (FFFF16) or is set to the state set by the V/I jumper (described on page 31) if the P/J jumper is in the jumper selectable position.

–The Channel Program Jumper Register (base + 1616) is set to program selectable for all channels (FFFF16) or to the position of the P/J jumper (described on page 31).

–The Channel Relay Control Register (base + 1C16) is set to open all channel relays (FFFF16).

–The Isolation Status Register (base + 1416) reflects the isolated/ non-isolated configuration of each channel.

–The Calibration Control Register (base +0816) is set to calibrate voltage with the cal mux disabled (200016).

–Channel Trigger Register (base + 1816) is set to 000016 if the module is a 16-channel configuration or FF0016 if an 8-channel configuration.

Note The upper 8-bits of all channel related registers are set to 1’s (FF 16) for 8-channel configurations.
