2.Using a clean cloth, dry the contacts by wiping from their inside to outside edge. This prevents particles from building up on the contact edges.
Do not use erasers to clean the edge connectors. They cause microscopic damage to the contact surface, removing the thin gold plating and exposing the nickel underplating, which eventually corrodes. Erasers also leave a film on the contact and generate static electricity.
Do not use paper of any kind to clean the edge connector contacts. Paper or lint particles left on the edge contact surface can cause intermittent electrical connections.
Do not touch contact or trace surfaces with bare hands. Always handle the board by its edges.
HP-IB Address Selection
The HP-IB address for the HP 8566B is preset at the factory by means of a five-segment binary switch located on the Al5 Controller Assembly. This switch is set to the binary number 11111 which corresponds to a decimal equivalent of 31. The number 31 is a special instruction code that commands the instrument to use the last input address stored in memory. This stored HP-IB address is ASCII 2R (decimal 18) and determines the address to be used on “power up.”
The HP-IB address may be changed to any of the addresses listed in Table 2 by resetting the HP-IB address switch to correspond to the binary equivalent of the desired ASCII character or decimal value as indicated in the table. The five-segment switch is illustrated in Figure 1 and is shown in its preset position (decimal 31).
