processing equipment.
B. Specifications
• RS232-C compatible Data Signal
• 7 data bits
• Odd Parity
• 9600 Baud Rate (+0.1%)
• Two Stop Bits
• US-ASCII Character Set
• Mark = -3 to -15V
• Space = + 3 to +15V
• Maximum distance of 50 cable-feet
• Connector (at end of the attached cable)
DB9 Female for connection to a PC serial port
C. Character Frame
Characters are transmitted in an ASCII format at 9600 baud (+ 0.1%). The receiver
must be capable of a tolerance of 9600 (+/- 2.5%) baud to allow for line losses and
frequency skew. Character frame consists of one start bit, 7-bit character length, odd
