What is a BLN1203? It looks like it can perform System Timer functions as well as other things... Is it a first-gen AIMI card?
Can someone give me the DIP switch and jumper settings for this card? Ideally I'd like to use it as a System Timer only...
Thanks!

If it is an AIMI board(MOL says Master Control Board)
The dip switches on a AIMI set the address like any normal CEB card.
Normally this is set to 5F but it doesnt matter.
The AIMI always supports one full-duplex T1 or E1 link to the AEB. In addition, for a CEB collocated with the AEB, a unidirectional Manchester link carrying audio from the AEB to the collocated CEB accompanies each E1 link. For remote CEBs, a similar option exists which allows a second T1 or E1 link to be connected between the AEB and CEB if more audio resources from the AEB to the CEB are required. TDM bus timing and data
bus arbitration is performed by the System Timer section of the AIMI. This section of the AIMI replaces the CEB System Timer module which is normally used in non-Embassy CEBs. In addition to these primary functions, the AIMI supports system data communication with all other CEB modules.
The second major function of the AIMI provides CEB TDM bus timing and data bus arbitration signals. In an Embassy system, the TDM buses in the CEBs must be synchronized with the AEB. In order to accomplish this, the AEB uses a master clock which is used to transmit bits onto all its links. The link interface circuit of each AIMI recovers this clock and passes it to its System Timer section for generation of the TDM bit rate clock. In this manner, the CEB TDM buses operate at the same nominal rate as the AEB TDM buses. The AIMI System Timer also uses this clock to generate other systemtiming signals including signals which arbitrate usage of the system data bus
so maybe not but give it a try

Yeah, hence the reason I get no audio. I spoke with the Console Group about this today, and they confirmed it is an obsolete, first-gen AIMI, and cannot be used standalone as a system timer. Oh well.
By chance Bruce, are you familiar with setting up DCCM (Digital Channel Control Modules) on B&L consoles?
I'm running II+ TOMI v3.96 and my OP's have 1988 firmware in them, and I am trying to set up the display DCCM's so they display the channel name... I set the DCCM up in the Series2 RSS, I set up the alias and associate the alias with the BID code of the BIM that the DCCM is set to control, but I still get a blank display no matter what I do.
Am I missing something, or is my firmware too old, or what?

1.At the operator position where the default assignments are
to be entered or modified, simultaneously press and release
the Shift () and Assign keys on the MCP.
2. On the DCCM whose default assignments you wish to
modify, press the Select switch.
3. Assign a talkgroup to that DCCM using either the scroll or
keypad method. The DEFault LED temporarily lights to
confirm that the default assignment is being changed.
4. Exit the assign mode by pressing the Assign switch.
