- Only a BA-11L can drive mopre than one LTC load. So cut R63 on all DL-11Ws
- except the one you enable as 'clock'.
-
- The switch setting for a DL-11W are:
-
- Bus address S5 1=off, 0=on , order (msb) 3 2 1 4 5 6 8 7 (lsb)
-
- Vector S2 1=on, 0=off 8 7 5 3 6 4
-
- Baud rates Xmit
-
- S4-10 S3-1 S3-4
- 110 on on on
- 150 off on on
- 300 on off off
- 600 on off on
- 1200 on on off
- 2400 off off off
- 4800 off off on
- 9600 off on off

- Yeah, the inverse of Xmit...
-
- 20mA stuff...
-
- Xmit Active: s1-1, s1-2, s1-7 on; s1-3,s1-6 off
- xmit passive, invert above
-
- Rec active: s3-6, s3-8, s3-10 on; s3-7, s3-9 off
- Rec passive, invert
-
- Reader Run active: s1-4, s1-8, s1-10 on; s1-5, s1-9 off

- Data bits

- s4-4 s4-3
- 5 on on
- 6 on off
- 7 off on
- 8 off off
-
- Stop bits
-
- 1 s4-5 on
- 1.5/2 s4-5 off
-
- Parity, s4-6 on to enable, s4-2 on for even, off for odd
-
- Break bit S4-1 on to enable
-
- Error enable s4-7 on
-
- RTC S5-9 S5-10
- On off on
- off on off
- only on on *** if RTC only is used. No SLU. Addr == 77754X!!

- Fun, fun board to sett up...
