Installing the 87130A Attenuator/Switch Driver

Connecting Switch Drivers to Switches and Attenuators

Using External Drivers A standard switch driver can control up to seven external 84940A driver cards.

Each driver card has 31 4-pin black output connectors numbered J1 to J31 (silkscreened on the circuit side of the PCA) which connect to relays.

Each relay is referred to as a channel by the switch driver. Therefore, there are a total of 248 relays (channels) that can be driven from a single switch driver.

Each card must have a unique address. (Refer to Figure 2-10). The internal driver card is set to card 1. On card 1, J1 to J31 correspond to channels 100 to 130 on your switch driver channel menu. Card 2 would correspond to channels 200 to 230; card 3, 300 to 330, and so forth up to card 8, 800 to 830. All of these channels are set with the drive enabled.
