Features
The MODBUSCARD provides UPS systems with the functionality of communication with PCs through MODBUS protocol:
• Implements MODBUS RTU protocol
• Provides MODBUS functions including Read Coils, Discrete Inputs, Holding Registers, Input Registers, Write Single Coil and Single Register
• Provides RS-422/485 and RS-232 interfaces (PC communicates with UPS via RS-422/485 or RS-232 or both at the same time)
The MODBUSCARD should be installed in the accessory slot intended for Tripp Lite’s SNMPWEBCARD.
Remove your UPS system’s SNMPWEBCARD from its accessory slot. Align the MODBUSCARD with the guides in the accessory slot and push the card
into the slot until the ports are nearly even with the rear surface of the UPS.
If your UPS system does not have an SNMPWEBCARD installed, use a screwdriver to remove the accessory slot cover from the UPS. While the UPS is
turned on, align the MODBUSCARD with the guides in the accessory slot and push the card into the slot until the ports are nearly even with the rear surface
of the UPS.
Important Installation Note: Be sure to fully congure all your MODBUSCARD’s switches to match your conguration before installation.
