Async Comms Channel Settings Definitions:
Each channel of the Async module has its own settings page. The following is a list of the available
settings:
Baud Rate
Used to select the Asynchronous baud rate of the channel. Available options are 38400, 19200, 9600,
4800, 2400, 1200, and 600 baud.
timeslot start bit
Sets the least significant bit of the timeslot on which the data is placed. 0-7 may be chosen. Time slot
is transmitted MSB (most significant bit) first, which is bit 7. The amount of bits used is determined
automatically from the baud rate (see table below). Time slot sharing is only allowed between the two
channels of a single Async module, not between two modules. For example with 19200 baud and 4 as
the timeslot start bit, bits 4 through 7 are used for this channel.
***Users of Nokia brand multiplexers should note that Nokia documentation considers the most
significant bit as bit 1 and least significant bit as bit 8. So in the above example using bits 4 through
7, Nokia configuration should be bits 1 through 4 or a bitmask of 11110000.
Table 7-1. Timeslot Baud Rate
bits per char (incl. start and stop)
Sets the number of bits per character, including start, data, parity, and stop bits. 9, 10, and 11 are the
available options. Possible character formats are listed on the following page:
