‘Azebān (Ott. Sing. ‘azeb), which were mostly deployed to the castles along with the rivers and seas, were one of the most important components of the Ottoman fortresses. They constituted the flotilla forces in the castles situated by rivers or seas. The commanders, also known as kapudān/captain, were responsible for commanding these flotilla groups for various purposes.
...
‘Azeb units were divided into three groups with regard to their sub-professions. The first division was made up of the ‘azebān-i piyāde, which served on foot. These soldiers made up the largest portion of all the ‘azebān forces in the fortresses. In the year 1491, while the total number of ‘azebs in the fortress of Semendire reached 850, 733 of them were infantry. The second ‘azeb group consisted of soldiers who served as mounted cavalry. They were either called ‘ulūfeciyān-i süvārī or fārisān. Lastly, the third category was ‘azebān-i kāyık or ‘azebān-i kāyıkhā-yi hassa whose members were assigned to protect or operate the boats in the castles located by the sea or river.
...
‘Ulūfeciyān-i süvārī means mounted soldiers who paid in cash and fārisān also means mounted soldier. These terms were used interchangeably in the documents. For instance, the roll-call list of the ‘azebān units in the Semendire Fortress from the year 1488 listed 100 mounted ‘azebāns as fārisān. See: KK.d. 4725, fol 109a. However, the same mounted ‘azebāns were written as ‘ulūfeciyān-i süvārī in the roll-call list which was registered in 1491. See: MAD 15334, p. 89.
Насколько понимаю - конные азапы могли быть отмечены в документах и просто как azebān-i süvari.
Конные азапы упомянуты в Щит и меч султана. Армия Османского государства в конце XVI - начале XVIII в. среди расквартированных на Крите войск. Сообщения об азапах и фарисах - на страницах 142-145, бешли - 155.

Fārisan or ulufeciyan-ı süvari were cavalry units. They were mostly responsible for the organizing raids in the enemy lands and preventing enemy raids around the fortresses. Therefore their duties was not in the fortress. Due to their role in raids, Fārisan troops were generally assigned to the fortresses in the border region. In the 16th and the 17th centuries, prevailed in fortresses as cavalry units. Some members of this group were tımar holders, while other members were salaried troops. There were two possibilities that were discussed for the identity of fārisan troops in the frontier regions. As the first possibility, it is claimed that fārisan troops were the mounted ʿazeb troops. As the second possibility, it is said that levends who served under the household of a high ranked official were the fārisan troops. Any record of any type of fārisan troops in the Eastern frontier could not be found in the payroll registers belongs to the beginning of the 17th century.

In the fortresses of the Hungarian frontier, the biggest groups were ʿazebans, fārisans, müstahfizans, and gönüllüyans. In the East, gılmān, gönüllü, ʿazeban and müstahfizan troops were the largest groups. Also, as it was mentioned above, some types of troops can only be found in one frontier. These are gılmān, fārisan, and martolosan. It is not possible to encounter with the name of gılmān in the payroll registers of the Hungarian garrisons. ... Moreover, the name of fārisan troops only can be found in the registers of the Hungarian garrisons, their absence could be explained in a similar way just like gılmān troops, inaccessibility of the registers for the period.

The farisan (sing. faris, from Arabic) were salaried cavalry troops and were considered provincial troops, like the azeban. These troops were neither part of the kapıkulu cavalry units nor were they timar-holding sipahi cavalry. Several other terms were used to refer to mounted troops in garrisons, including atlı ulufeli, mounted salaried, ulufeciyan-i süvari, salaried riders, and beşlu, or “fiver,” which alluded to their earning five akçe per day. This latter term continued in use even after the troopers’ salary increased. By the seventeenth century the term faris is the one most frequently used in documents.
P.S. И это только азапы на жаловании. =/
