5.87 Switches 2,3, and 4 select the data speed for 
synchronous transmission only. 
Switch 2 = 2400 bps 
Switch 3 = 4800 bps 
Switch 4 = 9600 bps 
5.88 If asynchronous operation is used, the 
switches will have no effect and the data speed will 
self-adjust to a maximum speed of 19.2 kbps or 
less. 
5.89 A power ON/OFFswitch that appears on some 
early DDIU-MAT models controls power to the 
DDIU-MAT from the power supply. If the switch is...

2) Carefully separate the two halves of the DDIU- 
MA to expose the S2 and S3 (DTE/MODEM) 
switches (Figure 4-41) in the upper left corner 
of the DIUB PCB. 
3) If the DDIU-MA is to be connected to a DTE, 
both switches must be in the DTE position. If 
it will be connected to a DCE, both switches 
must be in the MODEM position. 
4) Reassemble the DDIU-MA.
