3. Configuration 3.1 PB-SIO4A Address Map and ID Byte The PB-SIO4A is addressed (odd byte access) by using the carrier board base address and one of the following offsets for the piggyback location: Piggyback location A ( the upper position on the carrier board)
Configuration 3.3 Jumper Settings The jumper positions B53 to B69 are located on the rear side of the PB-SIO4A and are solder bridges. Jumpers B51 and B52 are located on the front side of the PB-SIO4A and if installed are wire bridges. They are set at the factory as required and should not be changed.
3.4 Pinouts 3.4.1 PB-SIO4A/Carrier Board Connector ST101 This is a thirty pin, dual row male header connector which provides interfacing between the PB-SIO4A and CPU side of the carrier board. Table 3-2: Pinout of Connector ST101 Signal Signal +5V (Vcc)
Configuration 3.4.2 PB-SIO4A/Carrier Board Connector ST102 This is a twenty-six pin, dual row male header connector which provides interfacing between the PB-SIO4A and the application side of the carrier board. Table 3-3: Pinout of Connector ST102 Signal Signal +RxD D...
