The corner station PEM model, h1pemcs is supposed to have all the DAC channels on the 18-bit DAC in the h1oaf0 computer. These had been stolen some time ago by a "compact BRS" model. Checking with Jenne, this was decommissioned some time ago, so I reconnected the 0, 1, 2, 3 DAC channels back to h1pemcs. I restarted the model, did not require daqd restart.

Now these channels can be used for whatever injections, connecting to the 18-bit DAC in the PEM rack. Channels such as H1:PEM-CS_GDS_<#>_EXC, where # can be 0 thru 6, as labeled on the front of the chassis.
