Input
A20 A14 Phase A pulse input
EIA Standard RS-422-A Line receiver
(AM26C32 (manufactured by Texas
Instruments Incorporated) or equivalent)
The line receiver specifications are as follows:
• VIT + Differential input on voltage
(H level threshold voltage) 0.2V
• VIT - Differential input off voltage
(L level threshold voltage) - 0.2V
• Vhys hysteresis voltage (VIT +- VIT -) 60mV
(Current type line driver cannot be used.)
