PROSCEND 850G-12PI Industrial Ethernet Switches

Connecting Power
The 850G Series Industrial Ethernet Switch can be powered from two power supplies (input range 12 ~ 58 VDC for non-PoE Series, 54 ~ 58 VDC for PoE Series). Two power supplies are on the top panel of the switch. Insert the positive and negative wires (AWG 14-26) into V+ and V- contacts on the terminal block respectively and tighten the wire-clamp screws to prevent the wires from being loosened.
- Non-PoE Series

- PoE Series

WARNING
The DC power should be connected to a well-fused power supply.
Alarm Relay and Ground
- The alarm relay output contacts are in the middle of the DC terminal block connector as shown in the figure below.
- The alarm relay out is “Normal Open”, and it will be closed when it is detecting any predefined failure such as power failures or Ethernet link failures.
- The relay output with current carrying capacity of 0.5A @ 24 VDC.
- The switch must be properly grounded for optimum system performance.

Console Connection

The console port on the top panel is for local management by using a terminal emulator or a computer with terminal emulation software.
- DB9 connector connect to computer COM port
- Baud rate: 115200bps
- 8 data bits, 1 stop bit
- None Priority
- None flow control
To connect the host PC to the console port, a RJ45 (male)
connector-to-RS232 DB9 (female) connector cable is used (not included in package). The RJ45 connector of the cable is connected to the console port of the switch; the DB9 connector of the cable is connected to the PC COM port. The pin assignment of the console cable is shown below:
DIN-rail Mounting
STEP 1: Use the screws to install the DIN-rail kit to attach at the rear side of the switch.
STEP 2: Hook the unit onto the DIN-rail.
STEP 3: Push the bottom of the unit towards the DIN-rail until it locks in place.
NOTE: For all switches (Non-PoE Series, PoE Series), the operation of DIN-rail mounting is the same.
Wall Mounting
Use the screws to install the wall-mounting kit to attach at the rear side of the switch.
NOTE: For all switches (Non-PoE Series, PoE Series), the operation of wall mounting is the same.
