This is from the Viper Website:
“ESP2 is Viper’s exclusive serial communications protocol that allows extra ultra-security, high speed communication between systems and enables many of Viper’s key features.”
Sounds good but what does this actually mean?
First of all, it allows me to program the alarm with a Bit Writer
A Bit-writer is a programming tool that allows an installer to customise any Viper (Or any Directed Electronics alarm) that has an ESP2 plug.
Without a Bit-writer programming is limited to some simple options. With the Bit-writer, I am able to program different functions to each remote programmed to the alarm.
For example, remote #1 could be programmed for silent arming, and remote #2 could be programmed for arm/disarm chirps to be turned on.
This Video gives a quick taster:
Programming options vary between system. There are a heap of fine-tuning options to play with. For example, I can adjust how long the siren sounds for when the alarm is triggered. Be it 30 seconds, 31 seconds or much longer. I can also change the functions on the auxiliary outputs.
The Bit Writer allows me to lock the alarm form program access. So without a Bit Writer new remote controls cannot be added. This helps to prevent remote cloning.

The ESP2 plug can also be used to add a 1502T digital battery back-up siren to selected alarms.
