● Provides a user-definable, 40-line parallel interface with bit, byte, pulse and string data transfer capabilities. Fully configurable to the user's needs by bus commands. ● Pull up resistors on all inputs for switches and CMOS signals. Handles TTL/CMOS signals and contact closures. ● Monitors up to 15 input lines for level changes. Automatic event and status change detection. ● Fast RS-232/RS-485 interface operates up to 115.2 Kbaud. Also supports network protocol. ● IEEE-488.2 Compliant with SCPI Commands. GPIB functionality over a serial link. ● Interchangeable with ICS's 4803 GPIB and 8003 Ethernet Interfaces. Convert from Serial to GPIB or Ethernet (LAN) interfaces replacing a card. ● Support includes a menu driven configuration program and SERkybd program. Easy configuration and serial command generation.
Model 2303 Serial <-> Digital Interface Board provides 40 programmable bi-directional data lines for controlling devices, for transferring digital data or for monitoring digital signals. The 2303's serial interface provides all of the functionality of a GPIB interface but allows for control of the digital signals over an RS-232 link or over an RS-485 network. A user setable address lets multiple 2303s be operated on a RS-485 network with other RS-485 devices.
Provides RS-232 full duplex and RS-485 (RS-422) half duplex asynchronous serial interfaces. Unit automatically responds to the serial interface that receives the command.
