Serial Data and Self-test
Serial characters are received with data formatted as a 10-bit word. The command set is structured to
allow transmission of 8 data bits. The data rate is fixed at 9600 baud. The level is EIA-232C.

Self-test is a very useful feature and can be activated by sending 1F-40 (HEX). The test may be
terminated by sending 1B-40 (HEX). Characters from 20 (HEX) to F4 (HEX) will be displayed advancing
through the characters at approximately 2.0 characters per second. This self-test capability can be used to
speed up both in-field fault isolation and incoming receiving inspection.
