Sep 05, 2014 You need to connect to the RJ-45 style serial port on the UPS. That is the correct port since yes, only AP9630/31 Network Management Cards have the console port directly on them. I don't know about the markings on the cable you mentioned but the molded DB-9 connector should have one of those part numbers on it if it is the APC cable.

APC Smart UPS DB9 cable pinout. APC Part# 940-0024C, # 940-0024B, # 940-0024D or 940-1524 (black cable). Compatible with most APC UPSs that have a DB9 serial port. Should work with APC PowerChute or Apcupsd (UPS Server for Linux) This pinout is associated with 84 compatible devices or models. Serial port: Access internal menus by connecting this port (RJ-11 modular port) to a serial port on your computer, using the supplied serial cable (APC part number 940-0144). The cable 940-0144 on amazon would cost me 95$ with shipping and tax. There is one on ebay a bit cheaper.

RJ45 Ethernet Cable Pinout

Ethernet LAN cables can come in two different types – Crossover or Straight through. Most modern communications equipment can auto-sense which type you are using, but some still need the correct cable pinout. The following are the pinouts for the RJ45 connectors so you can check which one you have or make up your own. It doesn’t matter if you are making up some Cat5e, Cat6, and Cat7 cables. The pinout is always the same for Ethernet cables.

Straight Through LAN Cable Pinout

Straight through LAN cables are the most common, and the pinout is the same if they are Cat5e, Cat6, or Cat 7. The different types of cables (category or cat) offer increasingly faster transmit and receive speeds. This is achieved by increasing the wire twists, better shielding, drain wire, and increased wire diameter.

There are two different pinout standards used worldwide, and depending on your location, you will determine which one you should use. An easy way to remember the two different RJ45 connector pinouts is T568A is used in America and Asia, and the T568B is used in Britain(UK) and Europe. The different pinouts will still work if you mix them up.

• T-568A – Most commonly used in the USA and Asia – Think A for America
• T-568B – Britain (UK) and Europe

RJ45 Pinout for a LAN Cable

• Pin 1 → White and Green (Transmit +) wire
• Pin 2 → Green (Transmit -) wire
• Pin 3 → White and Orange (Receive +) wire
• Pin 4 → Blue wire
• Pin 5 → White and Blue wire
• Pin 6 → Orange (Receive -) wire
• Pin 7 → White and Brown wire
• Pin 8 → Brown wire

Remember that Pin 1 is on the left hand side of the RJ45 connector with the clip at the rear.

Crossover Ethernet Cable

Crossover Ethernet cables are used to connect two devices of the same type. Like you want to connect two routers or two PCs. Most modern IT equipment can auto-detect that a crossover needs to be made and makes changes to the signal. This is called MDI-X. A crossover LAN cable will connect the receive at one end to the transmit at the other. Care must be taken to identify a crossover cable clearly so it is not used by mistake as this may cause network outages. These cables are sometimes made with a cable that has a red outer sheath.

RJ45 Pinout for a Crossover LAN Cable

• Pin 1 ← White and Green wire → Pin 3
• Pin 2 ← Green wire → Pin 6
• Pin 3 ← White and Orange wire → Pin 1
• Pin 4 ← Blue wire → Pin 4
• Pin 5 ← White and blue wire → Pin 5
• Pin 6 ← Orange wire → Pin 2
• Pin 7 ← White and Brown wire → Pin 7
• Pin 8 ← Brown wire → Pin 8

How to Crimp an RJ45 Ethernet Cable

Follow these steps to make sure you make the perfectly crimped RJ45 connector:

1. Trim the outer sheath back about 10mm to expose the inner conductors.
2. Trim off any nylon strands or wire guides.
3. Straighten the wires.
4. Sort them out to the correct color codes for the pinout.
5. Snip the wires so they are all the same length.
6. Push the wires into the connector.
7. Make sure the outer sheath is inside the RJ45 crimp.
8. Crimp the connector.
9. Test the Ethernet cable.

What is the Maximum Length of an Ethernet Cable?

The recommended maximum length for any structured cabling is 100m. This includes 5m of patch cables at either end of the cable run, so the fixed cabling’s actual distance is 90m. Anything over this distance will start to introduce interference and losses on the cable, which will be seen as errors, dropped traffic packets, and reduced throughput.

Structured Cabling = 90m

LAN Patch Cables = 2 x 5m

It’s good installation practice to keep the cable runs as short as possible and avoid unnecessary excessive service loops of cable.

What pins does Ethernet use?

An Ethernet cable RJ45 connector has 8 pins. Pins 1 & 2 (green) and pins 3 & 6 (orange) are used for data communications while pins 4 & 5 (blue) and pins 7 & 8 (brown) are not used.

How many pins does Ethernet use in a RJ45 connector?

An Ethernet cables uses a RJ45 connector that has 8 pins. Pin 1 is on the left hand side while holding the connector with the tab facing away from you.

What is the maximum length of an Ethernet cable?

The maximum length of any Ethernet cable (Cat 5, Cat 6 or Cat 7) is 100m or 328ft before any loss of traffic occurs. Over 100m the traffic will start to get errors and reduced speeds.

A RG45 connector is commonly used on an Ethernet cable in computer networks. RG45 stands for Registered Jack No.45, has 8 pins and is crimped on to the cable.
