Usually we receive the following questions from customers that are installing a Linear access control system:
What’s the maximum distance you can go with an RS-485 connection?
The RS-485 is limited to a total of 4,000 feet. This is a per-network distance meaning the total length of all cable runs within a network should not exceed 4,000 feet.
How Far can I run an RS-232 (serial) Connection?
40 to 50 feet (12m – 15m) is the practical maximum distance using Enhanced CAT5 cable. Some technicians have made longer runs, but this isn’t recommended.
Although these topics are very useful to do a correct installation, always check with the instruction manual provided with the system and remember that we always recommend hiring a qualified company/installer to do the job.

Question: Albert wanted to know… Can I program a replacement Linear MCT-1 Transmitter / Remote myself? I already have one but I would like to get a backup transmitter. I was wondering how to clone it?
Answer: Good morning Albert, lucky for you that MCT-1 transmitters cannot be cloned. They are meant to be programmed thru the “learn” button on your receiver or entered into a system by their device ID number. This makes them very secure and possibly one of the most widely used transmitters in gated community applications.
Alberts reply… So it looks like I will need to hire someone to program it. We live in a condo so I don’t think I can locate the gate learn button, also the original transmitter does have a 4 digit sticker on it. How would I enter the code ID manually? Does it require special software?
Second answer: Actually Albert, if you have a management company, they are the ones that probably would be in charge of doing that, if not them, I am sure that either, one of the HOA members is doing it or they have hired an access control company to do it for them. Either way, the best way is to ask one of the members of the HOA and they can point you in the right direction.
Question: Michael would like to know… Where is the smart button located on the Linear DRA 1 Channel Receiver for my gate?
Answer: Well Michael, it is not… the Linear DRA receiver is not a “learning” receiver. It is programmed by a set of dip switches inside that need to match the dip switch settings on your remote transmitters. So if you have a programmable “learning” remote, you may want to take a look at a Linear AP-5 receiver which will allow you to program your transmitters.
Question: Donovan asked us… Can I access the Linear RE-1 from another location that is not from inside the house?
Answer: Good evening Donovan, per your recent email inquiry, the answer is yes, the RE-1 when connected to a POT’s line (plain ole’ telephone line) from your local provider, can be programmed to remotely answer your call and allow you to speak and monitor your front gate, open and/or hold open your gate. However it also has an “intercom mode” with this type of connection it will generate its own ringtone, thus it will only allow you access to the system from whichever house phones it is connected to.

Question: Adrian in Texas wanted to know… How do I program my Linear keypad to hold my gate open until I am ready for it to close?
Answer: Well Adrian you will need to program your Linear AK Keypad with a latch code…
To program your keypad into latch mode do the following, enter:
# 9 # 123456 (Master Code)
01 # 1479 # 1479 # 30 #
**# (to save and exit programming mode)
Hope this helps!
