Table 1. Connector J1 Detailed Description (UART Communication) UART Interface PIN SIGNAL DESCRIPTION The MAX3232PMB1 peripheral module can interface to Clear to send. This pin carries the clear- the host by plugging directly into a Pmod-compatible 1 CTS-H to-send signal from the connected DTE port (configured for UART) through connector J1. to the Pmod system. J1 provides connection of the module to the Pmod host. The pin functions and pin assignments adhere to the Host transmit. This pin carries the Pmod UART Type 4 standard recommended by Digilent. transmit data from the Pmod system 2 TXD-H See Table 1. UART transmitter to a connected DTE receiver. This J2 connector is meant to interface to a data terminal (DTE) through a standard RS-232 cable or a DCE device Host receive. This pin carries the receive through a null-modem RS-232 cable. See Table 2. 3 RXD-H data from the connected DTE transmitter to the Pmod systems UART receiver. Jumper JP1 (CTS/RTS) This jumper port allows CTS and RTS to be passed Ready to send. This pin carries the ready through, looped back, or disconnected from the local 4 RTS-H to send signal from the Pmod system to a connected DTE. and remote system. In most applications, these jumpers should be set in pass-through mode with pins 1-2 and 5 GND Ground 3-4 shorted. 6 VCC Power supply Maxim Integrated Products 2
