7-4 Programming Considerations
Table 7.2. Standard LPT-10 and FTT-10 Channel Definition for both Bus and Free
Topologies
Variable FT-10 Standard Transceiver Type
Comm Mode Single-ended (see note 3)
Comm Rate 78.13kbps
Min Clock Rate 5MHz
Num Priorities 4
Osc Accuracy 200ppm
Osc Wakeup 0µsec
Avg Packet Size 15 bytes
Collision Detect No
CD terminate after preamble No
CD through packet end No
Bit Sync Threshold 4.0 bits
Rcv Start Delay 9.0 bits (see note 1)
Rcv End Delay 0.0 bits
Indeterm Time 24.0 bits
Min Interpacket Time 0.0 bits
Turnaround 0 µsec
Missed Pream 4.0 bits (see note 2)
Use Raw Data? No
Notes:
1. For N repeaters in a packet path: Rcv Start Delay = 4.5 * (N + 1) bits
2. For N repeaters in a packet path: Missed Pream = 2.0 * (N + 1)) bits
3. Use Differential mode when emulating an FT-10 channel on the LonBuilder backplane
