Hardware Overview
Ethernet Port Connector
The Ethernet Port connector is a standard RJ-45 receptacle that allows the serial server to be connected to an Ethernet network. It also carries Power over Ethernet (PoE) based on the IEEE 802.3af standard.
On the PES1A/ PESV1A two indicator LEDs are built into the RJ-45 connector.
Serial Port Connector
The Serial Port Connector is a DB-9 male connector (configured as a DTE) supporting RS-232 serial communications including TD, RD, TRS, CTS, DTR, DCD, DSR and GND signal lines. Use a standard serial cable if connecting to a DCE; use a null modem (crossover) cable if connecting to a DTE.
Refer to Appendices D, E and F for connection pin-outs.
Power Connector
Power is supplied to the PES1A/PESV1A by PoE (Power over Ethernet) via the RJ-45 Ethernet receptacle. Power over Ethernet may be delivered via un- used pairs in the CAT-5 cable, or via a simplexed power technique. Both options are supported by the PES1A and PESV1A. PoE power consumption for the PES1A and PESV1A are rated Class 3.
Refer to Appendix E for Ethernet connection pin-outs and additional information on PoE.
Output Power Connector (PESV1A only)
The output power connector (on the PESV1A only) is a two position removable terminal block that provides a DC power supply voltage output (derived from the PoE input power) in three selectable ranges: 5 VDC, 9 VDC and 12 VDC. Maximum output power is 4 watts.
