2-CHANNEL ASYNC TDM
3. Installation
Installation of the 2-Channel Async TDM is simple
and straightforward.
Refer to Table 1-1 for the factory setting. If the
factory setting does not suit your requirements,
you can change it as follows:
Remove the cover by pressing the four markings
on the sides.
Strapping information for individual straps is
printed on the PCB of the TDM.
1. Determine the data rate, which should be the
same for both channels, and strap DATA RATE
to the speed appropriate for your equipment.
The setting represents the rate of the sub-
channel.
2. Select the parity, even or odd, for each
channel, by strapping PARITY SELECT
(SW1 and SW2) to the appropriate position.
If no parity, select either even or odd.
3. Select the number of stop bits for each
channel by strapping STOP BITS (SW3
and SW4) to the appropriate position.
