MGR10 A/B/C - Revision : I (for 7.0 software revision) 61PPU Parallel Poll UnconfigureParallel Poll is not implemented. This command is ignored.SPE Serial Poll EnableThis establishes serial poll mode for all responding talker devices on the bus. When they areaddressed to talk, each responding device will return a single 8-bit byte of status from eachdevice. Devices which recognise this command must have Talker interface capabilities to allowthe device to output the status-byte.SPD Serial Poll DisableThis terminates serial poll mode for all responding devices, returning the devices to theirnormal talker state when they output device-dependent data rather than status information.MLA My Listen AddressThis is sent by a controller to indicate to all other bus devices that it has become a listener.UNL UnlistenThis unaddresses all current listeners on the bus. Single listeners cannot be unaddressed withoutunaddressing all listeners. It is necessary that this command be used to guarantee that onlydesired listeners are addressed. The ‘Lstn’ legend is turned off. (Device address 31 is illegal andis the address sent by UNL to unaddress the device).MTA My Talk AddressThis is sent by a controller to indicate that it will be the talker from now on. All other busdevices must “un-talk” on receiving this command.UNT UntalkThis unaddresses the current talker. Sending an unused talk address would accomplish the samething. This command is provided for convenience since addressing one talker automaticallyunaddresses another. (Device address 31 is illegal and is the address sent by UNT to unaddressthe device). The ‘Talk’ legend is turned off.PPE Parallel Poll EnableParallel Poll is not implemented. This command is ignored.PPD Parallel Poll DisableParallel Poll is not implemented. This command is ignored.
