6. GPIO (Inputs and outputs)
6.1 Overview
All input and output signals pass through the GPIO (General Purpose Input and Output) module.
The GPIO module consists of a Look-Up Table (LUT – Cross-Point Switch), 2 Pulse Generators
and a 12-bit counter. In the LUT, the relationship between inputs, counters and outputs is
governed by internal register set-up.
Fig.7 GPIO interface
In the BM-500GE and BB-500GE, the relation for the external interface is fixed as below.
Line Signal Connector
Line 1 TTL Out 1 D Sub 9P pin #4
Line 2 TTL Out 2 D Sub 9P pin #8
Line 3 Optical Out 1 Hirose 12P pin # 7/8
Line 4 Optical Out 2 Hirose 12P pin # 9/10
Line 5 Optical In 1 Hirose 12P pin # 5/6
