Equustek's DL3500 comes in 4 models. The DL3500-Modbus/DH+ and DH-485 become Modbus Masters for devices on A-B's DH+ or DH-485 networks. The DL3500-Modbus/DH+ and DH-485 become Modbus Slave devices for access to PLCs on A-B's DH+ or DH-485 networks. Master mode is used when a device on the DH+ network is going to initiate all communications with one or many Modbus slave devices. Slave mode is used when a device on the Modbus network is going to initiate all communications with one or many SLCs, PLCs or other DH+ devices. The DL3500-Modbus/DH+ or DH-485 is a two port device that bridges your Modicon Modbus devices to A-B DH+ network. The Modbus model can either be used as Modbus Master or Slave as well as having both Modbus ASCII and RTU protocols.
The DL3500 has two communication ports. Channel A is designed to
connect to you industrial network, either A-B's DH+ or DH-485 networks.

depends on which flavor (model) of the DL3500 you have ordered. Channel B
has the capabilities of RS232C, RS422, RS485 and USB 2.0. CHA can be configured for DH-485 at 4800, 9600 or 19.2 Kbaud, or DH+ of 57.6, 115.2 and 230.4 KBaud. CHB has full RS232C, as well as both RS422 4 wire and RS485 2 wire modes. CHB has the ability of being configured with
asynchronous speeds upto 230.4 KBaud as well as the new Plug and Play Windows USB Interface. Both CRC 16 and BCC error checking can be implemented; custom error checking can be added at the customer's request. See the Equustek website for spec sheets on all four device models.
