1746-BAS | BASIC MODULE

The 1746-BAS is a SLC 500 SLC BASIC Module. This SLC BASIC Module has RS-232/423, -422, -485, and DH-485 Communication Ports for connection to modems, printers, Human Machine Interface and other devices. It also has a 24KB battery backed-up RAM and for data and user program storageThe 1746-BAS module features communications ports such as PRT1, PRT2 and DH485 communication interfaces. PRT 1 is exclusive used for interfacing the BAS module to user devices via transmission speeds of 300, 600, 1200, 2400, 4800, 9600 and 19200 Baud Rate in full duplex mode. This port may be configured for RS232,423 / 422, 485 modes. PRT 2 may also be used with user devices and also for interfacing modem using DF1 protocol. It is also capable of RS232 / 423, RS422 / 485 communication modes with same Baud Rates as PRT1. The DH485 communication terminal is used for DH485 network. It is a non-isolated port and requires the use of 1747-AIC to connect the port to DH485 network. It is important to remember that when PRT2 is configured as DF1 or used for interfacing to a modem, the DH485 communication port is disabled
