Frequently Asked Questions

What types of encoded media (badges) can be used with Synel terminals?

Synel terminals can be used with barcode, proximity, magnetic stripe, and Weigand (e.g., HID, Indala) badges.

Are there any limitations on the number of employees or locations for SYNEL terminals?

Synel terminals are scalable, to grow with your company. When using the internal memory, the terminal can accommodate thousands of employees, and by using the host database directly, its capacity is limited only by the type of database. SYNEL terminals can accommodate multiple locations operating anywhere around the world.

Can SYNEL terminals be used on their own or do they require a host computer?

SYNEL SY-XXX series terminals have the ability to collect validate and store transactions as an off-line, or ‘stand-alone’ unit, provided they are equipped with batteries. These terminals can perform in on-line mode (with host validation), off-line mode (batch processing), and/or a combination of both.

In the off-line mode, if the terminal cannot communicate with the host, it automatically validates and stores transactions internally. When a transaction cannot be validated locally it will request validation directly from the host database, and reject the request if the host is not available.

When host communications are re-established, the terminal can be configured to automatically send the stored transactions to the host.

In an on-line mode, all transactions performed at the SY-XXX series terminals will be sent immediately to the host for validation, processing, and return messaging.

What communication cabling can be used with Synel terminals, and what are the maximum terminal distances from the host computer?

SYNEL provides multiple communication options to suit the distance requirements and cabling of each implementation. SYNEL communicates via RS-232, RS-485, modem, and Ethernet.

Type of Cable Type of Communication Recommended Maximum Distance Configuration/
number of terminals
RS-232 Point to point 50 feet Maximum of one terminal per host, via serial connection.
RS-485 Direct 6,000 feet Facilitates communication with up to 32 terminals per serial port.
Modem 1200, 2400 or
14,000 baud rate
n/a Standard analog telephone line (often can be shared with fax or data line); automatic transfer of transactions to host may be scheduled.
(Cat 5)
Wired or wireless TBD by network configuration Terminals are assigned an IP address and connect to existing Ethernet. This connection can be established via Ethernet cabling or wirelessly with Synel’s 802.11 or Blue Tooth technologies.


What are the recommended cabling, cable installation and mounting guidelines for SYNEL terminals?

Communication cabling guidelines:

1. Always use the cable recommended by Synel.
2. Thread communication and power cables a safe distance away from high voltage power supply cables.
3. When using shielded cable, make sure the ground wire is properly attached.
4. For longer-range cabling, use at least 22AWG shielded cable, or consult Synel’s Technical Support team
5. For RS232/485/422 cable, use shielded twisted-pair cable.
6. For aerial installation, use NYY-shielded cable.
7. If the SY-65 converter is required (for multiple terminals or long distances) place the converter no more than 15 yards from the host PC, using 22AWG cable with RS-232 communication.
Guidelines for the installation of communication cables:
1. Install the cable away from sources of EMI (electromagnetic interference) such as:

  • Motors, generators, alternators, and transformers
  • Air conditioners, elevators
  • Radio/television transmitters, signal generators and internal communication networks
2. Cables should be installed at least:

  • 1 foot (30 cm) away from 5 KVA power lines.
  • 2 feet (60 cm) away from 5-10 KVA power lines.
  • 5 feet (1.5 meters) away from power lines exceeding 10 KVA.
3. Cables may run parallel to power lines for a maximum of 50 feet (15 meters).
4. Ideally, use a single, continuous cable for the communication line. If this is not possible, the cable should have only one indoor connection, with two connectors with appropriate shielding and covers, inside a connection box.
Mounting Guidelines:
For the user’s convenience, mount the terminal at a height of approximately 4-1/2 feet, or about 1.4 meters (measured from the top of the terminal to the floor), at a distance of 6″ or 15 cm. from a wall or other obstruction on the right side (closer to the sensor).

How are IP addresses assigned to the Ethernet terminal?

A Network Administrator assigns the IP address, subnet mask and port designation either at the terminal keypad in ‘Setup’ mode, or via the host. SYNEL Ethernet terminals work with both static IP addresses (assigned by your network administrator when your server and terminal device is configured) and dynamic IP addresses (randomly assigned from a pool of addresses each time you logon to your network).

Are SYNEL Ethernet terminals compatible with Microsoft and Novell networks?

Because the TCP/IP protocol is the same for virtually all network operating systems, Synel Ethernet terminals work with both Microsoft and Novell networks.
